▼ Metsien kiertoajan muuttaminen on yksi Kyoton Artiklan 3.4 mukainen metsien hiilinielua lisäävä toimenpide. Kustannustehokkaiden keinojen löytäminen ilmastonmuutoksen hillitsemiseksi on ilmasto- ja ympäristöpolitiikan näkökulmasta tärkeää.
Tässä tutkimuksessa selvitettiin, miten kiertoajan pidentäminen ja hiilensidonta vaikuttavat metsänkasvatuksen kannattavuuteen. Metsänomistajan taloudellista optimikasvatusta verrattiin kiertoajaltaan 10 ja 20 vuotta pidempiin kiertoaikoihin niin, että niillä saavutetusta hiilensidonnan lisistä maksettiin korvausta. Metsänomistajalle aiheutuvia kustannuksia hiilensidonnasta selvitettiin ja vertailtiin saataviin tuottoihin.
Tutkimuksen metsikkökoealoiksi valittiin 5 männikköä ja 5 kuusikkoa Itä-Suomesta, ja niiden kehitystä simuloitiin Motti-metsikkösimulaattorin avulla.
Tutkimuksen tuloksista kävi ilmi, että metsät sitoivat enemmän hiiltä pidemmillä kiertoajoilla, mutta hidastuvasti. Kiertoajan pidentämisestä aiheutuvat hiilidioksiditonnin yksikkökustannukset olivat välillä 2,3 – 18,1 (€/tCO2) kuusille, ja 0,2 – 15,9 männyille. Hiilensidonta oli kuitenkin keskimäärin voimakkaampaa ja kustannustehokkaampaa kuusikoissa kuin männiköissä. Metsänomistajan tulojen nettonykyarvot kasvoivat lähes jokaisessa tapauksessa, joka osoittaa että hiilensidonta metsien kiertoaikoja pidentämällä on kustannustehokasta oikeissa olosuhteissa.
Hiilinielukaupan keskeneräisyys on esteenä kaupalliselle metsien hiilinielukaupalle. Vastaisuudessa tarvitaan lisätutkimuksia sille, miten nämä ja toimintamallit saadaan täytäntöön ja uusia kehitettyä.
Cost-effective mitigation of climate change is essential for climate policy. Forest rotation age is a silvicultural measure by which forest carbon stocks can be influenced with in accordance with the Kyoto Protocol, Article 3.4.
The purpose of this study was to evaluate how lengthening the forest rotation periods would affect the profitability of forestry and carbon sequestration. The discounted net revenues of the forest owner’s economical optimal (Faustmann’s rotation model) were compared with 10 and 20 years longer rotation periods, where the additional carbon dioxide sequestrated was compensated with prices 20 € and 50 € per ton of CO2. All calculations were made with a 2 % and a 4 % interest rate.
Ten test sites were selected from a list of forest stands in Eastern-Finland, 5 of which were Norway spruce stands and 5 were Scots pine stands. The forest growth of these stands was simulated with Motti-simulator, a software developed by Metsäntutkimuslaitos (METLA) to estimate tree growth at forest stand levels.
The results indicate, that lengthening the rotation period increases the carbon stocks of forests. The additional carbon dioxide sequestrated obeys the rule of decreasing marginal utility, so that the increment is greater for the first 10 years than the following 10 years lengthening of lengthening. The unit costs for carbon sequestration were between 2.3 – 18.1 (€/ton of CO2) for Norway spruce and 0.2 – 15.9 for Scots pine. However, the carbon…

▼ Urban and industrial settings represent potential
areas for increased
carbon (C)
sequestration and storage through
intensified tree growth. Consisting of an estimated 1270 ha of land
once entirely forested, Burnside Industrial Park (BIP) in
Dartmouth, Nova Scotia. Our study examines the degree to which
intensified urban tree planting within the BIP ecosystem could
enhance C
sequestration and storage. This was achieved by
conducting a geospatial analysis in combination with construction
of a C model. Three scenarios urban
forest development were
examined. If all potential planting spots are filled with trees by
2020, an estimated 26,368 tC, at a
sequestration rate of 635 tC/yr,
could be achieved by 2050. Next, we explored the challenges and
opportunities associated with pursuing C offset markets as a means
for funding urban
forest development within BIP. A basic framework
from which a community?based C offset market could potentially be
established was recommended.

▼ The objective of this research is to evaluate the long-term effects of wood harvesting and
sustainable
forest timbering practices on
forest biomass and
carbon sequestration in West
Virginia. Although several
forest management and
carbon models have been coupled for scenario
analysis, this integrated modeling approach is novel as it predicts timbering events, disturbance
events, and
forest stand growth as endogenous processes operating at multiple scales (tree, stand,
region, and state). This approach allowed for simulating a number of key micro-scale, cross-scale
feedback mechanisms, including the long-term interaction between
forest stand volume
dynamics, growth, timbering event frequency, and disturbance event frequency at multiple scales.
The results of the logistic regression analyses indicated that timber stand value density, tree
prices, and plot ownership were key drivers in predicting timber stand and tree selection for
commercial timber removal events. Beyond the direct effect of timbering events (i.e., removal of
forest biomass), timbering events in West Virginia did not have a statistically significant indirect
effect on net annual
forest stand growth rates, landscape level disturbances, regeneration rates,
nor mortality rates. Overall, the integrated model estimated that the average net annual growth
rate for West Virginia in 2000 for the validation dataset was 1.38% (1.33% was the 5 year
average), which was within 1% of the observed rate of 1.40%. From 2000 to 2050, aboveground
biomass and
carbon stocks in West Virginia forests are projected to continue to increase, despite
increased timbering activity, with nearly half of the state
forest acreage being classified in an
advanced stage of recovery from past timbering by 2050 (up from 28% in 2000). However, the
rate of annual increase in
forest carbon and biomass decelerates over time. This deceleration is
due to a projected doubling of the timber removal rates toward mid-century (due to increases in
timber prices and stand density), increases in landscape scale disturbances, and declining stand
net annual growth, which are all due to increases in stand density.
Forest stands with steeper
slopes, lower annual average precipitation, and greater stand volume density were more likely to
experience a landscape disturbance event, resulting in a net negative growth rate for the stand.
Overall, these disturbance events are projected to increase in frequency by approximately 50%
from 2000 to 2050, as
forest stands increase in stand biomass density. Application of sustainable
timbering techniques was found to significantly enhance long-term projections of biomass,
carbon, net annual growth (50% higher than status quo), and system carrying capacity.

▼ Afforestation does not only establish new forests on treeless lands, but also changes many other aspects of the ecosystem, including the fauna, ground vegetation and soil properties. One of the most important ecosystem changes is the influence on the ecosystem carbon (C) stocks in different aboveground and belowground C pools. If afforestation is to be used as a method to sequester atmospheric carbon dioxide (CO2), to mitigate climate warming, it is important not only to consider changes in aboveground tree biomass, but also in the other four major ecosystem pools (dead wood, ground vegetation, litter layer and soil organic carbon (SOC)). The true CO2 mitigating potential of afforestation is the net change in all those five pools, but especially the last two pools have often been neglected in prior studies.
Here I present a study of three afforestation sites in SW Iceland named Heiðmörk, Nesjavellir and Ölfusvatn forests. Heiðmörk is the largest site, planted with different coniferous tree species since ca. 1950 and also contains large naturally regenerated (self-seeded) areas of the native downy birch (Betula pubesecens). The Nesjavellir and Ölfusvatn forests are younger, since ca. 1997, and the former has planted stands of both birch or conifers and also some naturally regenerated areas self-seeded from local birch forest remnant, while the latter only has planted stands of either birch or conifers.
To examine the influences of afforestation: i) between sites, ii) between different forest types and iii) with respect to increasing forest age, the present study compared different ecosystem properties of adjacent treeless control sites with afforested areas. The ecosystem properties included: i) ground vegetation cover, composition and biomass, ii) soil physical properties (bulk density stoniness, soil and litter depths as well as soil and litter dry mass), iii) soil chemical properties (pH, SOC and N concentration in different soil layers, C/N ratio in both soils and litter) and iv) ecosystem C stocks (soils, litter, fine roots, ground vegetation and standing trees biomass). Another aim of the present study was to test if ecosystem C-stocks could be validated using minimum number of measurement plots in individual forests.
On average across all sites, forest types and forest ages, the soils of the forest sites had 12% larger SOC stocks compared to the treeless sites in 2017. Significant differences in the SOC stocks appeared mainly in the upper top soils (0-10 cm) depth. Litter C, necromass and thickness were also found to be significantly higher in the afforested sites, while ground vegetation was significantly reduced, but these properties also differed between forest types and with age of the forest. Soil bulk density, pH and C/N ratio were found to remain similar across all sites and species. Soils under conifer tree species were not found to become acidic contrary to what was hypothesized.
On average, pure coniferous plots contained somewhat higher SOC stock (10,991 g C m-2) than birch plots (10,340 g C…

▼ This explorative study provides a characterisation of
forest gain processes and related
carbon sequestration in Indonesia from 1990-2015. Satellite imagery and biomass datasets are analysed to characterise
forest gain and related
carbon sequestration. Global
forest resource assessments from the Food and Agricultural Organisation (FAO, 2010), the Joint Research Centre (JRC, 2014) and Hansen et al. (2013) are compared. The identified areas of
forest gain are visually interpreted using satellite imagery to validate whether gain occurred and to characterise for relevant attributes such as origin, former coverage, tree canopy cover density and dispersion pattern. The characterised gain is used to quantify related
carbon sequestration using biomass data from Langner et al. (2014) and IPCC (2006). The results reveal significant discrepancies between the existing datasets. Dissimilarities are found in the magnitude and the location of
forest gain and related
carbon sequestration. Compared to all Indonesian territory, the proportions of
forest gain are 0.4% for FAO, 0.6% for JRC and 3.1% for Hansen.
Carbon sequestration due to
forest gain is estimated at 698.6 tons C per km² per year for FAO. For JRC and Hansen this is 600.8 and 883.5 tons C per km² per year respectively. The origin of
forest gain is predominantly natural gain. For FAO natural
carbon sequestration is estimated at 5.2 times planted
carbon sequestration. For JRC this ratio is 2.2 to 1.

▼ This study explores the biophysical potential and economic attractiveness of black spruce (Picea mariana) regeneration in eastern Canada under future climate changes. It integrates process-based ecosystem model simulated forest productivities from three major global climate models (GCMs), growth and yield formulations specific to black spruce and economic analyses to determine the overall investment value of black spruce, both including and excluding carbon sequestration benefits. Net present value (NPV) was estimated to represent the financial attractiveness of long-rotation forest plantations through time. It was assumed that stands would not be harvested at volumes less than 80 m3 ha-1. The price of stumpage was set to 20 m-3, stand establishment cost was set to 500 ha-1, and the discount rate was considered at 4%, with sensitivity analyses conducted around these assumptions. The growth and yield of black spruce was simulated for an extreme future climate scenario – IPCC-RCP 8.5. The results suggested a general North-South gradient in forest productivity where gross merchantable wood volumes increased with decreasing latitudes. This pattern was also observed in NPVs, with higher values projected for the southern portion of the study area. Based on the base economic assumptions and sensitivity analyses, study results suggested that black spruce plantations are not economically attractive, unless carbon sequestration benefits of at least 5 ton-1 CO2 are realized. Further sensitivity analyses showed that discount rate plays a significant role in determining the optimal harvest age and value. Furthermore, the optimal harvest rotation age increases with increasing carbon price by approximately 9 to 18 years.

▼ Black
carbon (BC), a stable form of organic
carbon (OC), is a byproduct of the incomplete combustion of biomass, biofuels, and fossil fuel. The main objectives of this research are to examine the spatial distribution of OC and BC in urban soil and determine the influence of tree canopy cover and landscape maintenance on soil
carbon accumulation. Soil sampling was conducted at 29 sites throughout the City of Denton, Texas, in May 2019. Samples were collected from underneath post oak canopies and in adjacent open areas and were analyzed for total
carbon (TC), total organic
carbon (TOC), total N (TN), C:N ratio, and BC. Although maintenance levels had no significant effect, TOC was greater underneath trees (5.47%, 5.30 kg/m2) than lawns (3.58%, 4.84 kg/m2) at the surface 0-10 cm. Total nitrogen concentration was also greater underneath trees (0.43%) than lawns (0.31%) at the surface 0-10 cm. Preliminary results for BC were closely correlated to TOC. The lack of difference in C:N ratio between cover types indicates that leaf litter quality may not be the primary driving factor in soil C and N accumulation. Instead, differences in soil properties may be best explained by manual C inputs and greater atmospheric deposition of C and N to soils with tree canopy cover. Identifying patterns and potential drivers of soil OC and BC accumulation is important because soil
carbon sequestration not only reduces atmospheric CO2, but also may provide additional pollution mitigation benefits, thereby contributing to a more sustainable urban environment.

▼ Limited information is available on
carbon(C)sequestered in frigid Appalachian
forest soils. However,the cool moist forests of the high elevations probably hold more C than any other mineral soils in Virginia.
The objectives of the study were to determine the amount and variability of soil C across aspect and slope classes in a frigid temperature regime area of Tazewell County, VA.
Soils were sampled to characterize two aspect classes, N(340-90º) and S (160-270º), and three slope classes, 7-15%, 15-35%, 35-55%. Organic (L,F,H) and mineral layers and horizons (upper 5cm, A, B) were sampled at each site. Whole soil (including organic and mineral horizons) C contents on N aspects (135 Mg/ ha) were greater than on south aspects (107 Mg/ha). Average whole soil C across all sites was 112 Mg ha-1. The A horizons on N aspects (13cm) were deeper than those of the S aspects (8 cm), while average leaf litter weights were greater on the S aspects (25 Mg/ ha) versus the N (17 Mg/ ha). B horizon C was greater than 1.5 % and made up more than half of the total soil C.
Carbon increased with slope on N aspects, but did not increase with slope on S aspects, because estimated solar insolation potential decreases with increasing slope on N aspects and has no trend on S-facing slopes. Total C appears to be greatest on steep N-facing slopes because cooler and moister conditions promote better mixing of organic material into the mineral soil.

▼ Forest carbon sequestration is regarded as a viable and cost effective option for reducing global greenhouse gas emissions. Several research studies analyzed the effects of joint management of carbon and timber under different even-aged forest management scenarios, and concluded that carbon benefits can alter forest management schedules significantly. However, research specifically focused on the inclusion of carbon sequestration benefits into uneven-aged management has received little attention. This study determined the optimum joint management regime of timber and carbon in uneven-aged loblolly pine stands in Louisiana, and assessed management and financial effects resulting from the integration of carbon benefits into uneven-aged management. The USDA Forest Vegetation Simulator (FVS) –Southern (SN) variant was used to generate both growth and carbon data of uneven-aged loblolly pine stands. The generalized Faustmann model for uneven-aged management was applied to calculate the land expectation value (LEV) at every level of residual basal area and cutting cycle. In order to analyze the effects of changes in interest rate, stumpage prices, and future land values, comparative static analyses were carried out at three different interest rates, stumpage prices and future land values. This study determined the residual BA of 60 ft2/acre and cutting cycle of 18 years as the optimum timber management regime of uneven-aged loblolly pine stands at the interest rate of 4% and 2010 stumpage prices in Louisiana. Changes in interest rates and stumpage prices altered the optimum management schedules significantly, but effects of changes in future land value were minimal. In the joint optimization of timber production and carbon sequestration, carbon benefits were found influential in both financial and management perspectives. At every level of interest rates, the joint management of timber and carbon increased the LEV, extended the cutting cycle, and shifted the residual stocking to higher level. The joint management of timber and carbon under uneven-aged management is profitable, and the carbon offset would provide an important additional income source to landowners in the southern USA.

▼ Managing planted forests for carbon sequestration and biodiversity maintenance
has become increasingly important in times of rapid climate change and the loss
of biodiversity worldwide. The objectives of this study are to find out private and
socially optimal management strategies for planted forests, and suggest an
appropriate policy for promoting multiple-use forests.
The research attempts: (1) to identify the harvesting strategies of forest stands that
can maximise the benefits from timber production and carbon sequestration; (2) to
identify the patterns that can balance economic gain and biodiversity
maintenance; (3) to examine the actual management strategies and biodiversity
conservation attitudes of forest owners; and (4) to recommend policy tools that
can be used to align private with socially optimal decisions.
The Faustmann model is extended to include carbon sequestration, biodiversity
conservation, multiple forest stands and spatial arrangements among forest stands.
The Safe Minimum Standard Approach is employed to model biodiversity
conservation. The number of birds is used as a biodiversity indicator. A direct
search algorithm is used to determine optimal sets of harvesting strategies. The
models are applied to planted forests in Yen Bai province, Vietnam. To get
primary data, 291 household forest owners and 4 state enterprises, growing
Eucalyptus urophylla and Acacia mangium were surveyed.
The results show that the actual cutting ages are 5 and 7 years for household and
enterprise forests, respectively. Both the optimal timber and carbon rotation ages
are between 9 and 11 years for two species. The value of carbon uptake makes the
optimal rotation age slightly shorter. The incorporation of spatial arrangements
has little impact on the optimal rotation age, but significantly increases the net
present value. The inclusion of biodiversity conservation lengthens the rotation
age and significantly reduces the profitability of forest owners. Policy
implications are that payment for carbon sequestration services of planted forests
in Vietnam is feasible. Merging small forest stands of several forest households
should be encouraged. Direct payments are an appropriate policy tool to
encourage household forest owners to lengthen rotation ages in order to enhance
biodiversity.

▼ Timber and bioenergy production and forest carbon sequestration are intrinsically interrelated with one another. Consisting of four papers, this thesis addresses their interactions from different perspectives in Sweden. The motivation for the thesis is triggered by two of the national environmental quality objectives, Reduced Climate Impact and Sustainable Forests. The overall goal of the thesis is to increase understanding of the potential trade-offs and synergies between timber production, bioenergy, and forest carbon sequestration.
To achieve the goal of the study, a partial equilibrium (PE) model of Swedish timber market is calibrated in paper I and developed in paper II to paper IV. Respectively, in paper I the model is extended to include non-timber benefits and then the model is calibrated by finding a proper level of the non-timber benefits. By examining the interaction between timber production and forest sequestration under alternative hypothetical carbon prices, paper II estimates the cost of enhancing forest carbon sequestration. Paper III focuses on the impacts of increasing fuelwood demand on the Swedish forest sector. The interactions between three major timber products and forest resources are examined. Besides fuelwood, paper IV encompasses a wider range of biomass feedstock for bioenergy. The complex interdependence between bioenergy, timber production, and forest carbon are addressed explicitly. In addition, carbon balance associated with bioenergy expansion is projected over time to reveal the complex dynamics involved in forest-based carbon mitigation.
The results of these papers show that the inclusion of non-timber benefits in the forest sector modeling framework can more accurately reflect the objectives of forest owners. Promoting forest carbon sequestration in Sweden to mitigate climate change can be a relatively low-cost option, and it is more effective in the short term. The potential expansion of bioenergy will change the optimal mix of timber and non-timber products and services, causing competition between timber markets and affecting forest carbon. It is worth noting that the climate benefits of using bioenergy compared to fossil fuels are time dependent. The findings of this thesis will contribute to informing policymakers of the potential impacts of the different policy instruments, assisting them in handling trade- offs between sometimes conflicting policy goals.

▼ Objetivando estudar o seqüestro de carbono em sistemas de restauração florestal e discutir suas potencialidades e entraves perante MDL florestal, este trabalho teve dois objetivos principais: i) quantificar taxas iniciais de seqüestro de carbono nos compartimentos aéreo, radicular, solo e serapilheira, de plantios de restauração da Mata Atlântica, com 20 espécies (10 pioneiras, 10 não pioneiras), submetidos a manejos contrastantes (usual e intensivo), instalados sobre pastagem de Brachiaria no espaçamento de 3 m x 2 m; e ii) comparar os estoques de carbono destes sistemas, ao final do sexto ano, com valores determinados em fragmento de floresta madura vizinho ao ensaio. Ambos localizados em Anhembi/SP (Estação Experimental de Anhembi/USP e Mata do Barreiro Rico). O tratamento usual consistiu em adubação de base e capina mecânica na linha de plantio até dois anos, e, o intensivo teve adubações complementares e capina química em área total até dois anos. Foram desenvolvidos modelos alométricos de estimativa da biomassa através de amostragem destrutiva de 80 árvores, sendo quatro indivíduos por espécie, selecionados por classes de área seccional. Determinaram-se massa seca e teor de C, para os compartimentos copa, lenho e raízes. Através das equações, do inventário ao sexto ano e dos teores de carbono, foram calculados os estoques de carbono por compartimento, nos dois tratamentos. Determinaram-se os estoques de carbono na biomassa herbácea, serapilheira e solo. Foi calculada a variação de carbono por compartimento nos dois tratamentos. Os estoques de carbono na floresta madura foram quantificados utilizando dados de 10 parcelas de inventário, aplicados em modelo alométrico adequado para Mata Atlântica. A densidade da madeira variou até 3 vezes entre espécies (0,22 a 0,70 gcm-3), o teor de C foi pouco variável (46,5%). Foram adequadamente ajustadas equações de biomassa lenhosa, raiz e copa com base na área seccional, altura e densidade da madeira. A porcentagem de raízes é expressiva (30%) na biomassa total, mas as espécies não pioneiras mostraram maior razão raiz:parte aérea (0,32) que as pioneiras (0,28). A silvicultura intensiva elevou o crescimento do compartimento lenhoso em 250% (1,85 para 6,45Mg ha-1ano-1), devido a maior eficiência da copa e alocação de C no tronco. O carbono no solo embora representativo, não propiciou seqüestro em 6 anos, dada alta variabilidade espacial. O tratamento intensivo obteve maior seqüestro de C, atingindo 4,22Mg C ha-1 ano-1 (64% no tronco e galhos, e 20% nas raízes). Os estoques de C no solo e serapilheira foram próximos entre o sistema intensivo de restauração e floresta madura, sendo os estoques no tronco, galhos e raízes, o diferencial entre os sistemas. Com base no crescimento médio das árvores e estoque de C nas restaurações até sexto ano (7 e 21kg árvore-1 e 5,2 e 18,2Mg C ha-1, respectivamente no sistema usual e intensivo), e no tamanho médio das árvores e estoque de C na floresta madura (204kg árvore-1 e 138Mg C ha-1) estimou-se cerca de 50 anos para o sistema intensivo…

▼ Brasilian rannikkosademetsistä on enää jäljellä alle 12 % ja on siten yksi maailman uhanalaisimmista biotoopeista. Lisäksi monet rannikkosademetsän ennallistamisprojektit ovat epäonnistuneet puutteellisten metsänhoitomenetelmien takia. Samaan aikaan eukalyptus- ja mäntyplantaasien puuntuotanto Brasiliassa on kasvanut jopa nelinkertaiseksi intensiivisten metsänhoitomenetelmien (maanmuokkaus, lannoitus, ruohojen torjunta) ansiosta. Tällä tutkimuksella selvitetään näiden menetelmien vaikutusta rannikkosademetsän ennallistamiseen koskien puiden kasvua ja hiilensidontaa.
Kaksi koealaa perustettiin 2004 Brasilian itärannikolle leveysasteille 11°E ja 23°E, joissa tutkitaan intensiivisten metsähoitomenetelmien, istutustiheyden ja puulajikoostumuksen vaikutusta 20:n paikallisen puulajin kehitykseen. Tämä tutkimus keskittyy pohjoiseen koealaan, joka sijaitsee Bahian osavaltiossa 200 km Salvadorista pohjoiseen ja jossa vallitsee tyypillinen trooppinen ilmasto ja maaperä. Koeasetelmana on faktorikoe, jossa on kolme faktoria, joilla on kullakin kaksi tasoa (yhteensä 8 yhdistelmää). Faktorit ja niiden tasot ovat 1) metsänhoito; intensiivinen sekä perinteinen, 2) istutustiheys; 1667 puuta ha-1 ja 3333 puuta ha-1 ja 3) puulajikoostumus; 50:50- ja 67:33-suhteet pioneereja:ei-pioneereja. 8 vuotta istuttamisen jälkeen määritettiin puulajien selviytymisprosentti, maanpäällinen biomassa ja lehtialaindeksi, jotta saatiin selville eri faktoreiden vaikutus puulajien kehitykseen ja hiilensidontaan.
Tämän tutkimuksen päätulokset ovat: 1) Intensiiviset metsänhoitomenetelmät vähensivät kuolleisuutta ja lisäsivät puulajien varhaista kasvua 2) Harvempi istutustiheys (1667 puuta ha-1) sai parhaan hyödyn intensiivisestä metsänhoitomenetelmästä lehtialaindeksiin, puuntuotantoon ja maanpäälliseen hiilensidontaan liittyen 3) Intensiivinen metsänhoito lisäsi merkittävästi 19 puulajin kasvua 20:sta. 4) Ei-pioneeri -puulajit hyötyivät intensiivisestä menetelmistä suhteellisesti eniten 5) Perinteisten metsän ennallistamismenetelmien kanssa 67:33-suhde pioneereja:ei-pioneereja ja suurempi istutustiheys on suositeltava, jos halutaan saavuttaa mahdollisimman suuri puuntuotanto 8 vuoden iässä. Tehokkaan metsänhoidon kanssa suositellaan puolestaan 50:50-puulajisuhdetta ja harvaa istutustiheyttä.
Johtopäätöksenä voidaan todeta intensiivisten metsänhoitomenetelmien parantavan rannikkosademetsän ennallistamisen alkuvaiheen onnistumista lisäämällä monimuotoisuutta, parantamalla ei-pioneerien selviytymisprosenttia ja turvaamalla latvuston sulkeutumisen. Intensiiviset metsänhoitomenetelmät lisäsivät maanpäällisen hiilensidonnan kolminkertaiseksi 8 vuotta istuttamisen jälkeen verrattuna perinteisiin ennallistamismenetelmiin ja ovat siten hyvä menetelmä kun pyritään lisäämään hiilensidonnasta saatavaa hyötyä, kuten ilmastonmuutoksen vaikutusten lieventämienen.

▼ An understanding of ecosystem-level
carbon (C)
sequestration, or net ecosystem production (NEP), requires the separation of heterotrophic, microbial respiration (RH) from autotrophic, root-derived respiration (RA) as the components of RS (i.e., NEP = NPP - RH). However, separating these two sources in situ has been problematic since they are closely coupled. This study utilizes two similarly aged Pinus taeda L. stands, 8 and 9 years-old, aimed at quantifying these two respiration components through in-situ root severing. In order to use root-severing treatments to separate RS into RH and RA components, confirmation of carbohydrate depletion coupled to RA decline is crucial. This study evaluated the changes in CO2 flux rates and carbohydrate supply upon root severing in Pinus taeda L. using a controlled laboratory validating a two-part field study. The first field study used root-severing cores to test in-situ if respiration components can be attained based on the depletion of carbohydrate supply. The second field study was aimed at how future changes in climate might affect the ability of forests to store C and how modern forestry practices might affect changes and was conducted over the course of two installations, spring and summer 2012. In this study we examined the effects of fertilization (0 and 100.9 kg N ha-1 ) and throughfall reduction (0 and -30%) on total soil respiration (RS) as well as the heterotrophic contribution to RS, in a fully replicated (n=4), 2x2 factorial design. In the controlled lab experiment RS and RA declined by 86% and 95% respectively by the end of an 86 day trial and NSC carbohydrates declined by 60% for soluble, 29% for insoluble, and 43% for total (soluble + insoluble). The decline of RA was highly correlated to with the decline of NSC’s at 0.90, 0.69 and 0.93 for soluble, insoluble and total, respectively. The companion field study revealed a mean decrease 21±0.5% of over the final three dates when severed root respiration stabilized. In the second study, testing throughfall reduction and fertilization levels there were no fertilization by throughfall reduction interactions on the contribution of RH to RS in either the spring or summer; however, the main effect of throughfall reduction was significant in the spring. During the spring, the mean contribution of RH to RS for ambient throughfall plots was 96±6.4%, while the mean contribution under throughfall reduction was 68±1.9%. During the summer, there were no differences among treatments and the overall contribution of RH to RS was 78±1.6%. Collectively, both of these studies revealed that the severing of roots from their primary energy source and the subsequent depletion of stored NSC that the use of in-situ methods allows for the quantification of soil respiration components RA and RH. Using these estimates to model NEP in the short-term can be variable by season, however, long-term monitoring may simplify future NEP modeling scenarios

▼ Tämän tutkielman ideana on ymmärtää, kuinka metsiä voidaan hyödyntää ilmastonmuutoksen hillitsemiseksi. Tämä tutkielma esittelee käytännöllisiä metsänkäsittelymenetelmiä, jotka lisäävät hiilinielua Suomen metsissä. Näkökulma on markkinapohjainen ja perustuu vapaaehtoisuuteen.
Tutkimusmenetelmä oli simuloida kahta metsätilaa eri puolilta Suomea. Toinen metsätiloista sijaitsee Itä-Suomessa ja toinen Länsi-Suomessa. Molemmat metsät ovat mäntyvaltaisia, mutta Länsi-Suomessa sijaitsevassa metsätilassa on myös paljon kuusta. Itä-Suomessa sijaitseva metsätila on kasvupaikaltaan kuivahko kangas (VT) ja Länsi-Suomessa sijaitseva metsätila on tuore kangas (MT).
Kasvun, hakkuiden, puuston, hiilinielun ja hiilinielun kustannuksen muutokset analysoitiin vertaamalla eri skenaarioita. Tapion hyvän metsänhoidon suosituksia käytettiin perusskenaariona, johon kahta eri hiiliskenaariota verrattiin. Molemmille metsätiloille laskettiin nämä kolme eri skenaariota. Skenaarioissa muutettiin metsänkäsittelyä muuttamalla kiertoaikaa ja harvennusten määrää, ajoitusta sekä volyymiä. Hiiliskenaarioiden luomisessa ei käytetty esimerkiksi lannoitusta eikä istutustiheyden muutosta.
Tuloksena on, että metsien hiilensidontaa on mahdollista lisätä. Verrattuna perusskenaarioon, kokonaishakkuumäärä kasvoi 80-vuoden analyysiperiodin aikana, mutta muutokset puutavaralajijakaumassa olivat huomattavat. Kiertoajat olivat lyhyemmät, mikä johti pienempään tukkipuusaantoon ja suurempaan kuitupuusaantoon.
Hiilimetsänhoidon hyödyt alkavat näkyä vasta kymmenien vuosien päästä, mikä on pitkä aika sitoutua. Tulokset riippuvat metsän tilasta, eli kehitys- ja ikäluokkajakaumasta. Koska tämä tutkielma vertailee eri skenaarioiden eroja, yleispitäviä metsänhoito-ohjeita ei voida näiden tulosten perusteella johtaa. Tulisi tutkia tarkemmin, miten tämän tutkimuksen tulokset muuttuvat erityyppisissä metsissä. Hiilimetsänhoidon kustannus riippuu maksutavasta, mutta näillä metsätiloilla oli mah-dollista päästä kohtuullisiin kustannuksiin, eli alle 50 euroon.
Olennaisin johtopäätös on se, että hiilinielua on mahdollista lisätä kustannustehokkaasti Suomessa. Hyödyt alkavat kuitenkin näkyä vasta kymmenien vuosien päästä, mikä on pitkä aika sitoutua. Globaalilla tasolla on havaittavissa markkinamekanismeja hiilinielujen kasvattamiseksi, mutta se ei näy vielä Pohjoismaissa. Muutamat yksityiset yritykset ovat kuitenkin tehneet vapaaehtoisia toimia ilmastonmuutoksen hillitsemiseksi.
The purpose of this study is to understand how to utilize forests as a climate change mitigation method. This thesis introduces practical forest management methods that increase the carbon sink of forests in Finland. The perspective of this thesis is market-based and voluntary-based.
The research method of this thesis was to simulate two forest estates from different regions of Finland. The forest estate data consisted of two forests, one of which is located in Eastern Finland and the other in Western Finland. Both forests are pine dominated, although the one in Western Finland contains quite…

▼ Forests have the ability to alleviate the impact of global warming through
carbon sequestration. Six
forest management scenarios for a 27,000 acre study area are modeled to determine the impact of
forest management on
carbon sequestration.
Forest management determines annual harvested volume and end-use disposition category of wood products, and inventory volume. Shorter rotations tend to produce short-lived wood products, while longer rotations produce long-lived wood products. Thinning removes pulpwood, which increases the average diameter of the stand and increases the proportion of sawtimber products. Changing
forest management complicates accounting for changes in future C storage.
Understanding the distinction between pre- and post-regulation harvest volume and C storage is essential to understand the effects of
forest regulation. Plotting harvested volume and C storage volume over time shows distinctive pre- and post-regulation characteristics. The pre-regulation curves exhibit irregularities and varying thinned volume due to the uneven area in the existing age classes. Post-regulation curves are level because a constant area is annually thinned and clearcut.
Carbon storage is the amount of C that is sequestered into a C pool, which for the purposes of this study is either inventory volume or residual wood product volume. Converting volume flows to C storage involves tracking the accumulation of wood products and standing volume over time then converting volume to a measure of C. Once the
forest is regulated, C stored in the inventory pool remains constant from year to year, while the C stored in wood products continually increases. Longer rotations store more
carbon than shorter rotations because they have larger inventory pools. Wood products are a substantial
carbon pool: at the end of 50 years; the ratio of incremental C in the wood products
carbon pool to incremental C in the inventory pool ranges from 6 to 122 for the modeled scenarios.
Three accounting periods are evaluated to examine the importance of C
sequestration timing to determine if a market for C can influence
forest management. Long rotations meet the objectives of maximizing C
sequestration and NPV for the modeled regimes regardless of the accounting period considered, or if the
forest is regulated or un-regulated.
Model sensitivity to decomposition rate, discount rate and timber prices is assessed to determine the effects of uncertainty (measurement error and future trends) on the results of the model. Short rotations are most sensitive to decomposition assumptions and stumpage prices because they produce a large amount of fast-decaying wood products. Long rotations are most affected by discount rate.
Carbon storage of all scenarios increases substantially when the pulpwood decomposition rate equals the sawtimber decomposition rate to reflect a potential future increase in composite lumber production.

▼ ENGLISH ABSTRACT: Kiaat trees in Namibia are threatened by unsustainable harvesting practice. This study’s aim was to estimate the total value of an average Kiaat tree selected for harvesting with a focus on current timber use value, value of an optimally utilised tree, carbon value, and alternative uses of Kiaat trees. To accomplish this aim, the following specific objectives were set: (1) to estimate the total tree volume and optimum utilisable timber volume of an average Kiaat tree; (2) to estimate the amount and value of carbon stored in the above-ground parts of an average Kiaat tree; (3) to determine timber utilisation levels; and (4) to identify alternative use options to reduce timber losses of Kiaat trees. Previous studies on Kiaat in Namibia and elsewhere focused on growth, development and socio-economical aspects of Kiaat trees.
A combination of a socio-economic survey and tree volumes and biomass determination was used to collect data. The survey entailed Kiaat products assessment and face-to-face personal interviews with known key-informants in and around Rundu. Loggers with permits to harvest Kiaat trees were asked to harvest 40 Kiaat trees and data collected from each tree before and after felling included: lower-stem diameter, diameter at breast height (DBH), upper-stem diameter, stem length, stump height, recovered merchantable logs lengths and lower-and-upper diameters and lengths of branches greater than 10 cm in diameter. All canopy parts smaller than 10 cm in diameter were directly weighed, sampled and oven-dried at 105°C until constant weight. Volume of different tree parts was calculated and in combination with basic wood density used to calculate the biomass. It was established that a typically harvested Kiaat tree had an above-ground dry volume of 1.63 m3, of which 1.34 m3 (82%) was utilisable timber volume but that only 0.37 m3 (23%) was used and 0.97 m3 (59%) was left behind in the field. Merchantable logs were mainly cut into planks from which finished products - beds, chairs, doors and tables - were made. An average of 10.7 planks were cut per trunk and the local price of planks was N45.26 at the time of the study. More income is generated from finished products compared to selling loose planks. Canopy parts were mainly cut into woodcrafts – bowls, music drums, and walking sticks. Current timber use value (N484.73) surpasses carbon value (N123.74).
A further result of the study was that a significantly higher income could be earned for local livelihoods from Kiaat trees in the Kavango Region if trees were optimally used. Carbon trading is a noble conservation initiative, particularly when trees unsuitable for timber are considered. Use of timber trees exclusively for carbon trading is, however, not a viable option in respect of supporting local people’s livelihoods.

▼ This study focused on assessing the condition and creating a carbon inventory of forests in the Matiwane area of the Transkei. This entailed the use of aerial photography in tracing forest cover change from 1942 to 2007 coupled with ground-truthing to assess whether the forests have in any way endured degradation over the years with a potential reduction in carbon stocks as a result. This study revealed both the loss and gain of biomass in the area with a general trend of forests being continuously converted to agricultural fields resulting in reduced forest area, stem density, tree density and carbon loss in different pools of the forests, reflecting that these forests are degraded. The conversion has resulted in the reduction in the number of species from a mean of 11±0.57 species/200m² in intact forests to 1±0.23species/200m² plot in degraded forests. It was also revealed that approximately 5.2 % (791 hectares) of 15 352 hectares of forest area was lost as a result of the conversion of forest land to agricultural fields from 1942 to 2007 with 99 % of the clearing occurring in the last 33 years (1974-2007) and of which 60 % ( 4 77 hectares) occurred from 1995 to 2007, indicating that forest degradation in these forests is on the increase. The assessment also revealed some areas that were nonforest in 1942 that have accumulated woody biomass (BAA), composed mainly of Acacia sp accounting for 51.18 MgC.ha⁻¹ (Megagrams of carbon per hectare) and total carbon stocks of 0.02 TgC (Teragrams of carbon). The degradation of these forests induced a reduction in carbon stocks from 311.68±23.69 MgC.ha⁻¹ (to a soil depth 0-50 cm) in intact forest to 73.46±12.34 MgC.ha⁻¹ in degraded forests. The total carbon stocks in the degraded forests were approximated at 0.06 TgC and the BAA areas 0.02 TgC with 4.7 TgC in intact forests. The degradation of these forests has resulted in the net carbon loss of 0.19 TgC between 1942 and 2007 but 4.76 TgC is still locked in these forests. The large difference in carbon stocks between intact and degraded forests indicated the need to reduce the degradation of these forests to prevent further carbon loss and reduction of the carbon sequestration potential of these forests.

▼ Managing forests solely for
carbon sequestration and timber production objectives might have negative effects on the provision of water due to high losses from evapotranspiration. Therefore, information on the interactions among these three ecosystems services and how they are spatiallybundled can provide useful insights for land management decision making. This study used a US
Forest Services inventory data set and computed leaf area index (LAI)to quantify levels of provision and service bundles of
carbon sequestration,timber volume and water yield for slash pine sites in North Florida. Moreover,using a ranking classification approach, we determined spatially-explicit interactions among the services as well as the effect of drivers such as standage, site productivity, silvicultural treatments, ownership, and disturbance regime on individual ecosystem services and on the interactions (i.e., trade-off/synergy). Results indicated that growth in biomass reduced water yield during the study period. Nevertheless, this trade-off varied across space, as revealed by the lack of correlation in the model of water yield as function of net
carbon sequestration or timber volume. Specific areas of synergy among the 3 ecosystem services were found. Also, the results indicated that, although the effect of some drivers was not statistically significant on individual services, all the drivers analyzed affected the interaction among the services,with stand age, silvicultural treatment and site quality, the most significant.Finally, the framework developed in this study can be used to assess and manage natural ecosystems for multiple and optimal provision of services to people.

▼ The use of forests to reduce greenhouse gasses (GHG) hasbeen promoted as a cost-effective tool to deal with global warming. Thisdissertation uses one of the most comprehensive lists of Florida non-industrialprivate
forest landowners to examine the role of forests within a
carbon marketframework. First, it discusses the opportunities of Florida landowners toparticipate in existing
carbon markets. Followed by a description of theState’s forests and their
carbon capturing potential. Next, it describes theimplementation of two different conjoint choice tasks (best worst choice anddiscrete choice experimentation), which offer multiple options to estimateattitudes of landowners towards different
carbon programs, as well as variousavenues to estimate willingness to accept. Lastly, it simulates theimplementation of a
carbon-offset program to estimate the supply of
carbon inthe Northeast, Northwest, and Central areas of Florida.
Carbon markets often encourage
forest landowners tocapture
carbon in exchange for compensation, by using different platforms thatvary in terms of contract length, penalties for withdrawal, etc. Thesedifferences in available
carbon programs send signals to both consumers, andpotential producers of
carbon credits, which often cause confusion, pricevariations, and potential barriers to participation. This study examines thesebarriers and attitudes, to identify the
carbon market institutional componentsthat are best suited to engage Florida’s
forest landowners. Florida’s forests cover almost 50 percent of the State’sland area. These lands can play a key role in reducing GHS by approximatelycapturing 9.5 million tones of
carbon per year[1]. Despite the fact the majority (65%) offorests are owned by non-industrial private
forest (NIPF) landowners[2],no previous research has been done to assess their institutional preferencesregarding
carbon-offset markets. The results of indicate that landowners wouldneed between 20 to 30 acre-per-year to be positively affected by revenue,while the inclusion of penalty for early withdrawal increases cost ofparticipation by approximately 4.45 to 10.41 acre-per-year. This dissertation therefore investigates barriers toparticipate in
forest carbon markets in Florida, and estimates the supply ofoffsets for the most promising institutional arrangements. [1] See Mulkeyet al. (2008) [2]Florida 2010

▼ Forest carbon sequestration and storage is increasingly being considered as an attractive climate change mitigation strategy across the Northeast, the United States and the world. Recent research indicates that a significant percentage of U.S. reductions in
carbon emissions could be achieved through improved
forest management at costs competitive to other mitigation strategies and technologies. Given that the majority of forestland throughout the country is owned by many diverse private
forest landowners, the success or failure of
forest carbon management programs may depend on the willingness of these landowners to participate in voluntary
carbon offset programs. The goal of this thesis is to provide a better understanding of future landowner participation in
forest management programs specifically targeting
carbon benefits. Using a mail survey of 1,200 landowners in the Catskills region of New York State, a landowner's willingness to accept incentive payments in return for improved
forest management is determined using a contingent valuation approach. The landowner's utility-maximizing participation decision is estimated using a logit econometric model. Results of this study indicate that there is a strong interest among a broad spectrum of landowners for
forest management, especially among those concerned with climate change issues. Participation rates ranged from 30 percent at relatively low incentive payment offers to 85 percent at high incentive payment offers. The median incentive payment necessary to induce participation is between 14 and 19 per acre, per year. The participation decision is influenced by the amount of incentive payment offered, property size, different ownership objectives, attitudes towards climate change issues and political orientation. These results indicate that
forest management could be an efficient and effective climate change mitigation policy in the Catskills region of New York State, and possibly beyond.

▼ O presente estudo teve como objetivos predizer a produção volumétrica e o estoque de carbono nos fustes das árvores em povoamentos de eucalipto, por meio do ajuste de modelos de crescimento e produção, e avaliar economicamente a inclusão dos créditos de carbono nos projetos florestais, mediante o uso de critérios quantitativos. Para isso, utilizaram-se dados de povoamentos de Eucalyptus grandis localizados no município de Guanhães Minas Gerais. De posse das equações de volume e carbono para o fuste das árvores individuais e de 95 parcelas permanentes, ajustou-se o modelo de crescimento e produção de Clutter (1963) para projeção da produção volumétrica e do estoque de carbono. A classificação da capacidade produtiva foi obtida por meio dos índices de local, pelo método da curva-guia. A determinação das idades técnicas de colheita (ITC), considerando três classes de produtividade e os estoques volumétrico e de carbono por hectare, foi feita com base nos máximos incrementos médios anuais (IMA). A avaliação econômica e a determinação da rotação econômica foram realizadas, utilizando critérios quantitativos: valor anual equivalente, valor presente líquido, taxa interna de retorno, razão benefício/custo e valor esperado da terra e uma taxa de desconto de 10% ao ano. Após as análises, verificou-se que: o modelo de crescimento e produção proposto por Clutter (1963) foi adequado para predizer a produção futura volumétrica e do estoque de carbono, mantendo a coerência entre as idades técnicas de colheita e as capacidades produtivas; as idades técnicas de colheita (ITCs) foram praticamente iguais para o estoque volumétrico e para o estoque de carbono; há relação direta, na ordem de 86,15%, entre a produção de madeira, em m/ha, e o estoque de carbono, em tonelada de CO2/ha; os certificados de emissões reduzidas (CERs) contribuem positivamente para a viabilidade econômica de projetos florestais em locais de baixa produtividade; e, na análise de sensibilidade, a variação do preço da madeira foi o item que mais afetou a viabilidade econômica dos projetos. Por outro lado, os CERs influenciaram muito pouco.
The objective of this study was to predict the volumetric production and carbon stock in tree stems in Eucalypt stands, by adjusting the growth and production models as well as to economically evaluate the inclusion of carbon credits in forest projects by using quantitative criteria. Thus, data from Eucalyptus grandis stands, located in Guanhães-Minas Gerais, were used. Based on the volume and carbon equations for the stems of individual trees and for 95 permanent plots, the Clutter growth and production model (1963) was adjusted for volumetric production and carbon stock projection. Productive capacity classification was obtained by means of the local indexes, by the guide-curve method. Determination of the technical age of cutting (ITC s), considering three productivity classes and volumetric and carbon stocks per hectare, was carried out based on mean maximum annual increments (MAI). Economic evaluation and economic rotation…

▼ Individual tree detection and modelling forest parameters using Airborne Laser Scanner data (Light Detection and Ranging (LiDAR) is becoming increasingly important for the monitoring and sustainable management of forests. Remote sensing has been a useful tool for individual tree analysis in the past decade, although inadequate spatial resolution from satellites means that only airborne systems have sufficient spatial resolution to conduct individual tree analysis. Moreover, recent advances in airborne LiDAR now provide high horizontal resolution as well as information in the vertical dimension. However, it is challenging to fully exploit and utilize small-footprint LiDAR data for detailed tree analysis. Procedures for forest biomass quantification and forest attributes measurement using LiDAR data have improved at a rapid pace as more robust and sophisticated modelling used to improve the studies. This thesis contains an evaluation of three approaches of utilizing LiDAR data for individual tree forest measurement. The first explores the relationship between LiDAR metrics and field reference to assess the correlation between LiDAR and field data at the individual-tree level. The intention was not to detect trees automatically, but to develop a LiDAR-AGB model based on trees that were mapped in the field so as to evaluate the relationships between LiDAR-type metrics under controlled conditions for the study sites, and field-derived AGB. A non-linear AGB model based on field data and LiDAR data was developed and LiDAR height percentile h80 and crown width measurement (CW) was found to best fit the data as evidenced by and Adj-R2 value of 0.63, the root mean squared error of the model of 14.8% and analysis of the residuals. This paper provides the foundation for a predictive LiDAR-AGB model at tree level over two study sites, Pasoh Forest Reserve and FRIM Forest Reserve. The second part of the thesis then takes this AGB-LiDAR relationship and combines it with individual tree crown delineation. This chapter shows the contribution of performing an automatic individual tree crown delineation over the wider forest areas. The individual tree crown delineation is composed of a five-step framework, which is unique in its automated determination of dominant crown sizes in a forest area and its adaption of the LiDAR-AGB model developed for the purpose of validation the method. This framework correctly delineated 84% and 88% of the tree crowns in the two forest study areas which is mostly dominated with lowland dipterocarp trees. Thirdly, parametric and non-parametric modelling approaches are proposed for modelling forest structural attributes. Selected modelling methods are compared for predicting 4 forest attributes, volume (V), basal area (BA), height (Ht) and aboveground biomass (AGB) at the species level. The AGB modelling in this paper is extracted using the LiDAR derived variables from the automated individual tree crown delineation, in contrast to the earlier AGB modelling where it is derived based on the trees that were…

▼ With unprecedented changes in climate and land-use patterns, a decrease in global biodiversity and ecosystem services has been occurring at an alarming rate. This has resulted in a widespread damage to the life-support systems upon which every living organism depends on. Reforestation of degraded
forest ecosystems is now globally recognized as one of the best natural capital investment options, owing its contribution to biodiversity conservation, climate change mitigation and adaptation, and ecosystem services provision. The aim of this study was (1) to unravel confusions caused by the inconsistent use of terminologies describing different reforestation initiatives; (2) to investigate motivations behind recent reforestation initiatives; (3) to demonstrate the use of a restoration decision-making tool, Robust offsetting (RobOff); (4) to investigate the influence of climatic and edaphic factors on reforestation initiative, (5) to assess reforestation initiative success, and (6) to assess the impact of drought on reforestation initiative. A comprehensive review was conducted to unravel the confusion caused by the inconsistent use terminologies describing different reforestation initiatives, and to gain insight into motivations behind reforestation initiatives in recent literature (2000 to 2016). The results showed that there are 10 most common terminologies used to describe different reforestation initiatives. These terminologies were categorized into five groups based on their motivations, namely, (1) Creation or Fabrication, Reallocation and Replacement, (2) Ecological engineering, (3) Ecological restoration, (4) Reclamation, Reconstruction, Remediation, Renewal or Redemption, and (5) Rehabilitation. The recent reforestation initiatives were motivated by the need to reinstate resilient and more functional
forest ecosystems (through planting of a higher diversity of native tree species). This is because species diverse forests are more resilient and functional with significant contributions to biodiversity conservation (fauna and flora), climate change mitigation (
carbon storage) and adaptation (e.g., flood control) and ecosystem services that sustain society (e.g., food) and economy (e.g., employment opportunities). Using the Buffelsdraai Landfill Site Community Reforestation Project (BLSCRP) as a case study, RobOff, was employed to plan a complex large-scale reforestation. The complexity was caused by a mosaic of habitats (‗extant forest‘ and ‗former sugarcane fields‘) with varying levels of degradation, diverse reforestation actions (natural regeneration, current action,
carbon action and biodiversity action), a limited budget and multiple goals (biodiversity,
carbon stock and employment). RobOff results showed that investing in the restoration of ‗former sugarcane fields‘ through biodiversity action is preferable, because it achieved the highest biodiversity,
carbon stock and employment opportunities. Field trials were conducted at the Buffelsdraai Landfill Site to assess the influence of microtopographic…

▼ In order to fully understand the magnitude of the benefits that forests provide, it is crucial to understand the full suite of ecosystem services that they offer. A southern Appalachian red spruce-Fraser fir
forest was intensively analyzed using a variety of methodologies to determine the nature and quantity of some of these services. Many hypotheses exist regarding the future of these spruce-fir forests, which were heavily disturbed by the non-native balsam wooly adelgid during the 1980s. Direct measurements over the course of a decade assessed these hypotheses and indicate that this
forest is recovering structure and function. The
forest is accruing overstory biomass, with vegetation composition on a trajectory towards historic conditions. By using a total
forest inventory of all vegetation from overstory trees to understory mosses, rates of productivity and nutrient cycling were determined. Productivity of this
forest at low elevations has returned to pre-adelgid levels, while at high elevations productivity is approaching these levels. In the absence of an intact overstory,
forest understory vegetation can compensate by disproportionately cycling and retaining nutrients such as nitrogen that would otherwise leach offsite. The understory of this
forest provides an important service in nutrient cycling. Our ability to actively manage forests in order to manipulate levels and rates of
carbon sequestration was assessed using stand data and the
Forest Vegetation Simulator Growth and Yield Model. Silvicultural intervention proved effective at sequestering additional
carbon over a no action alternative by the end of our simulation period. This
forest provides a variety of ecosystem services and has retained its ability to recover their function after catastrophic disturbance.

▼ Increases in atmospheric C have resulted in concerns about global warming and interest in finding means to sequester atmospheric C through land management strategies. The purpose of this study was to (i) compare changes in mineral soil C after a 30-year interval and (ii) examine the role of inorganic-N, soil texture, and topography in these changes. Soil samples were collected at permanently identified points on the Camp Branch Watershed, a second growth oak
forest on the Cumberland Plateau in central Tennessee, in July of 1976 and archived. These points were re-sampled in July of 2006 and both archived and new samples of the 0 to 10 cm increment of the mineral soil were analyzed for C and N using the same procedures. Paired comparisons revealed changes in C and N were distinct to each of the 8 soil series. Comparison of 2006 samples to 1976 samples indicated changes in C concentration ranged from -13.1% to +12.0%. Changes in C mass ranged from -11.3% to +8.3%. Increases in C were most closely associated with increases in the C/total-N ratio. C was positively correlated to exchangeable inorganic-N in 1976 (r2 = 0.387) and 2006 (r2 = 0.107). Regression analysis revealed C increased with increasing azimuth and decreasing elevation in 1976 (r2 = 0.140). C was predicted only by clay content in 2006 (r2 = 0.079) and exhibited a negative relationship. Since topography was no longer a predictor of mineral soil C in 2006, we speculate that changes in
forest cover also influenced changes in mineral soil C.

▼ Forests can contribute to the reduction of carbon emissions by storing carbon in standing biomass or in products made of wood. Alternatively, harvested biomass can be used as bioenergy and replace fossil fuels. This thesis analyses the cost-efficiency of introducing forest carbon sequestration (FCS) into EU climate policy. Quantification of the potential and cost of FCS is important from a policy perspective, since this abatement method is being considered for inclusion in future EU climate policy.
The quantification in this thesis is based on a mathematical optimisation model that aims to find the least costly combination of abatement strategies to reach a specific carbon emission target. The model covers the EU-27 member states and can be applied in static and stochastic form (paper I) or dynamic form (paper II-IV). The main research questions investigated in the four separate studies are: i) The cost-efficiency and equity of including FCS in EU climate policy to 2020; ii) whether it is worth increasing FCS at the expense of bioenergy and forest products; iii) whether renewable energy forms (wind, hydro and photovoltaics) can compete with FCS as abatement methods; and iv) what the effects of climate change in terms of increased/reduced FCS will be during the current century and the accompanying implications on the cost of EU climate policy.
The results, which can be useful for policy making, demonstrate cost efficiency in using FCS as an abatement method. However, this may be at the expense of reduced equity among EU member states, since forests are distributed unequally throughout the EU. Furthermore, FCS seems to be a more cost-efficient option in terms of carbon abatement than bioenergy and, to some extent, forest products. This is also the case when comparing the cost-efficiency with that of renewables, even on modelling renewables with endogenous technological change in the form of learning-by-doing. The results provide indications of increasing FCS during the current century due to climate change, in particular in northern Europe, where warmer seasons and more precipitation are expected. This would have a positive effect on the cost of reaching the emissions target, meaning that the overall abatement cost would be reduced.

▼ Anthropogenic activities have globally increased nitrogen (N) deposition and carbon dioxide (CO₂) gas emissions. It is proposed that anthropogenic N deposition may increase the size of boreal forest CO₂ sink, because boreal ecosystems are N limited. Despite studies that have helped to clarify the magnitude by which N deposition enhances carbon (C) sequestration in the vegetation, there remains a paucity of studies evaluating how soils respond. This thesis aims to clarify the magnitude to which C sequestration in boreal forests responds to N enrichments, including rates that realistically simulated N deposition (≤ 12.5 kg N ha⁻¹ yr⁻¹). This work was conducted in two long-term experiments in northern Sweden. The N treatments consisted of ambient, low N addition (3-12.5 kg N ha⁻¹ yr⁻¹) and high N addition (50 kg N ha⁻¹ yr⁻¹) rates, in a Norway spruce and a Scots pine forest, maintained since 1996 and 2004, respectively. The organic soil C pool positively responded to N enrichment, especially at the high N addition level. This increase corresponded to a relationship between C sequestration and N addition of 10 kg C kg⁻¹ N. Further, low N addition treatments had no effect on microbial biomass and soil respiration (i.e. soil C outputs, microbial activity), while high N addition decreased total microbial, ectomycorrhizal fungal biomasses and soil respiration. The actinomycetes were the only microbes showing an increase with N addition. Annual litter production showed a minor impact on aboveground litter C inputs. Only mosses were the only major litter component showing significant quantitative and qualitative changes in response to N additions. Further, litter quality mediated by N enrichment was not the main driver of litter decomposition, while shifts in soil microbes strongly influence the early stages of litter decomposition. Low N addition rates had little effect on litter and humus decomposition, whereas high N addition rates impeded the early stage of decomposition of both substrates. The decline of litter decomposition appeared to be mediated by shifts in the abundance or community structure of saprophytic organisms, while the decrease of humus decomposition was likely the result of reduced ectomycorrhizal fungi. Altogether, the results of this thesis show that long-term N inputs simulating current atmospheric N deposition in the boreal region are likely to have subtle effects on the soil C balance and therefore on soil C accumulation.

▼ The studies presented in this thesis aim to increase our understanding of the long-term effects of anthropogenic nitrogen (N) input via fertilization or atmospheric N deposition on tree growth and forest understory in boreal forest.
Firstly, I studied the effects of low annual N addition simulating atmospheric N deposition on tree growth and variables linked to site fertility in two different forest ecosystems, i.e. on one Norway spruce (Picea abies [L.] H. Karst.) dominated site and on one Scots pine (Pinus sylvestris L.) dominated site (Paper I and II). On the P. abies dominated site tree growth and needle N concentration were higher on plots treated with 12.5 and 50 kg N ha⁻¹ year⁻¹ than on control plots, which only received background N deposition (1 to 2 kg N ha⁻¹ year⁻¹). P. abies growth increased linearly with 1.2% for every kg of N added, which corresponded to a net tree carbon (C) sequestration of approximately 19 kg C per kg N (Paper II). On the P. sylvestris dominated site tree growth increased linearly with 1.6% per kg N added.
Secondly, I studied carry-over effects of forest fertilization (150 kg N ha⁻¹) between tree generations. Growth of 10 years old trees on sites fertilized during the previous tree generation was measured (Paper III). On sites that were previously fertilized twice (25 and 33 years prior to my study), the young P. abies and P. sylvestris trees were on average 24% taller than trees on sites that had never been fertilized. Furthermore, the soil N mineralization rates were nearly four times higher and the amount of plant available soil-N two times higher on sites that were previously fertilized twice than on the other sites.
Thirdly, I studied the interaction effects between N form and N dose on tree growth, mycorrhizal fungi and on forest floor vegetation in a c. 50 year old pine forest (Paper IV). Five years after adding 50 and 150 kg N ha⁻¹ tree growth responded similarly on plots treated with the amino acid arginine (ARG) and on plots treated with ammonium-nitrate (AN). The basal area growth was c. 40% higher on the N addition plots than on control plots. The abundance of sporocarps (fruit bodies) of mycorrhizal fungi was significantly reduced in AN treated plots compared to ARG treated plots and the control. Both ARG and AN affected the forest floor vegetation, there was rapid increase of wavy hair-grass (Avenella flexuosa [L.] Parl.) following N addition, which remained throughout the study period. Also, at the end of the study period there was a decrease in lingonberry shrub (Vaccinium vitis-idaea L.) abundance on N treated plots.
In conclusion, I found linear relationships between N addition, up to 50 kg N ha⁻¹ year⁻¹, and P. abies and P. sylvestris growth. Also, I present data suggesting that the mechanisms affecting tree growth, on an ecosystem level, can be changed in the long-term by repeated N fertilization with 150 kg N ha⁻¹ occasion⁻¹. That is, N addition can promote a positive long-term effect on an ecosystem’s nutritional status. In addition, I show that…

▼ Le rôle joué par les forêts tropicales dans le cycle du carbone à l'échelle planétaire est majeur. Tant par les énormes quantités stockées sous forme de bois, que par les flux de CO2 séquestrées annuellement dans les troncs et le sol. Plusieurs études mettent en évidence des changements structuraux au sein des forêts pantropicales durant les 20 dernières années, notamment une augmentation de la dynamique (recrutement et mortalité) (Lewis et al. 2004b; Phillips et al. 2004b) et de la biomasse aérienne ligneuse en forêt Amazonienne (Baker et al. 2004a). Ces changements de dynamique ont été mis en relation avec une disponibilité accrue en ressources auparavant limitantes (azote et CO2) et donc liés aux changements climatiques globaux. Cependant, les processus de régénération après perturbation dans un peuplement forestier génèrent, eux aussi, une réelle accumulation de biomasse. Des perturbations endogènes (chablis, glissements de terrains) ou exogènes (sécheresses, tempêtes ou actions anthropiques) pourraient être à l'origine de ces fluctuations de dynamique forestière. Sans une connaissance approfondie de l'état initial des forêts étudiées, il semble difficile de distinguer, localement, une accumulation de biomasse liée à un effet de régénération de celle liée à un forge climatique. La présente thèse cherche à investiguer s'il existe des stades de régénération au sein d'un même massif forestier, qui illustreraient différentes perturbations asynchrones. Ces stades sont déterminés sur la base de la structure forestière (densité, diamètre quadratique moyen) et au travers de l'architecture des arbres. Après avoir estimé les flux, stocks et bilans de biomasse sur le site d'étude, ceux-ci sont mis en relation avec des stades de régénération, pour montrer que les parcelles sont formées d'une majorité de stades en croissance et que cela engendre une accumulation nette de carbone durant la période de suivi (1991-2009).
As living trees constitute one of the major stocks of carbon in tropical forests, assessing the role of these ecosystems in the carbon cycle received an increasing scientific and political interest. A better understanding of variations in the dynamics and structure of tropical forests is necessary to predict the potential of these ecosystems to lose or store carbon, and to understand how they recover from disturbances. Recent findings showed an increase of the turn-over in pantropical forests (Phillips et al. 2004a) and an increase of above-ground biomass in neotropical forests (Baker et al. 2004a). These results were attributed to an increasing availability of abiotic ressources (CO2, nitrogen) enhancing forest dynamics. Nevertheless, these findings were controversial and some scientists pointed out statistical and methodological errors (Lewis et al. 2006a; Wright 2006).The present project is based on a very different point-of-view and makes a nother interpretation of these results. The main hypothesis of this study is that the observed changes in forest dynamics around the Amazonian basin and in French…
