Harvest of plant products from the wild are an important source of livelihood to millions of people who live near forests. The impact of harvesting occurs at many levels to the ecology of the species. Harvesters are guided by their traditional ecological knowledge that also aids in reducing the impact of the harvest. I use the case study of Canarium strictum Roxb, (Burseraceae) a semi-evergreen tree harvested for resin by several indigenous communities in the Indian subcontinent. Resin is used locally for rituals and healing purposes and traded widely for industrial uses. I investigated the effects of resin harvesting on the ecology and phenology of the species on 89 trees in three regions of the Nilgiri Biopshere Reserve, Western Ghats, for two years. Seed germination experiments with seeds from harvested and not harvested trees were also undertaken. Through focus group discussions with harvesters, and using a fuzzy logic approach I documented their perceptions on the ecology of resin harvest and trees. I found that harvesting practices, size of the tree along with the characteristic of the tree flush colour were significant predictors of resin harvest. My results show that harvesting of resin has no negative effect on the growth rate, and fruit production. However harvested trees flowered at different times from not harvested trees and showed increased fruit production and seed germination rates. I found that resin harvesting was a prevalent practice among the indigenous people of the region and many of the factors perceived by the harvesters to influence resin quality and status of resin tree numbers in the forest coincided with factors observed in the ecological studies. Overall my results suggest that harvesting of resin has relatively low impact on the ecology of C. strictum and harvesters of resin make decisions on resin harvest based on a number of ecological factors. My results illustrate some of the detailed knowledge that harvesters have with regard to a lesser studied species like C. strictum, and community based monitoring programs that build on this knowledge can ensure strategies that allow for sustainable use while meeting the goals of conservation.

▼ Habitat fragmentation is one of the most pervasive threats affecting wildlife populations around the world. The resulting fragments are often small and isolated, increasing a population’s risk of extinction. Demographic variation, such as fluctuation in birth or death rates, can cause a small population’s numbers to plunge so low that recovery is impossible. Due to lack of gene flow, small, isolated populations eventually lose genetic diversity, become inbred, and suffer from inbreeding depression. These threats, however, can be reduced if there is some movement of animals, and gene flow, between populations. Unfortunately, movement of individuals between populations is restricted due to often unsuitable or even hostile environments separating the populations. Improving connectivity in these cases is vital for long term population persistence and viability. Therefore it is critical for conservation planning to include strategies that promote gene flow and metapopulation management strategies. The path to creating these successful plans begins with an understanding of the population’s status and the factors that affect movement in a fragmented landscape. The golden lion tamarin (Leontopithecus rosalia; GLT), an endangered primate native to the Atlantic Coastal forest in Brazil, lives in a landscape that is highly fragmented providing a perfect platform to investigate the effects of fragmentation and isolation on genetic status, movement, and long-term population viability. Currently around 1,600 GLTs are divided among at least 7 isolated populations (management units). The first study in this dissertation evaluates the genetic status of the reintroduced population of golden lion tamarins and determines if future reintroductions from captivity could further contribute to the wild population’s genetic diversity. Results indicate that the overall genetic status of the reintroduced GLT population is favorable; the population is currently maintaining relatively high levels of genetic diversity. However, this population is small and fragmented and is still at risk. Further reintroductions could enhance the genetic diversity and carefully selected translocations could help increase the genetic diversity of the isolated management units. This study demonstrates the power of using pedigree analysis for assessing wild populations and further using this information to make management recommendations for the conservation of the species. The second study investigates the level of connectivity in the GLT reintroduced population as well as factors that affect movement by examining the movements that occurred between groups and populations. This study demonstrates that distance is the most important factor that will affect movement in this fragmented population. Additionally, movement within seemingly connected habitats can actually be quite limited such that within a single management unit, there may be functional units that do not have movement between them despite their…

▼ Mammalian carnivores are a vital component of many ecosystems and can be particularly sensitive to human disturbance, even within protected areas (PAs). Our objective was to understand how human disturbance affects carnivore communities in southern Arizona, U.S.A., by studying habitat occupancy based on data collected using non-invasive methods in three PAs with different levels of human disturbance. We examined the impacts of human disturbance variables and disturbance level on carnivore occupancy, co-occurrence, temporal activity, and habitat associations. Carnivore occupancy varied based on human disturbance variables (i.e., roads, trails, etc.). Edges of PAs appeared to negatively impact occupancy of nearly all carnivore species. We also found that the presence of roads and trails, and not necessarily how much they are used, had a significant negative impact on the occupancy of most carnivore species. Furthermore, the overall level of disturbance within a PA influenced how sensitive carnivores were to human disturbance variables. Carnivores were more sensitive in PAs with higher levels of disturbance and were relatively unaffected by disturbance variables in a PA with low base levels of disturbance. In areas with low levels of disturbance, we found that many carnivore species have lower than expected levels of co-occurrence, which suggests spatial partitioning. As disturbance within an area increased, spatial partitioning became less prominent, and carnivores exhibited higher levels of temporal partitioning within these areas. We found that habitat associations varied among carnivore species, and associations were often different across different scales. We also found evidence of different habitat preferences in protected areas with higher levels of disturbance (e.g., avoidance of water sources). Information on the impacts of human disturbance is important when developing conservation plans, which is especially true for protected areas, given their important role in carnivore conservation, particularly as they are experiencing ever increasing rates of visitation.

▼ The bog turtle (Glyptemys muhlenbergii) is listed as threatened under the U.S. Endangered Species Act primarily because of the loss and degradation of its specialized wetland habitat. Adequate nesting habitat may be a limiting factor for bog turtle recovery, and nesting habitat creation or expansion may be an effective conservation tool but only if managers understand nesting behaviors, habitat requirements, and threats to nest success. The objective of this study was to understand the nesting ecology of the bog turtle and to use this information to suggest improvements to bog turtle management. I used radio telemetry to locate nesting females. I then used nest location and maternal genetic microsatellite data to investigate nest-site fidelity and natal homing. I collected microhabitat data at each nest and random points in both spring and fall at three spatial scales to understand nest-site selection. I also studied nest success with and without predator excluder cages to determine if predator excluders reduced predation or altered nest conditions. I found evidence that females display nest-site fidelity to nest-site areas but no evidence for natal homing. Bog turtles nested in relatively small patches of habitat in close proximity to water or saturated soil with low densities of woody stems and low percent cover of woody vegetation, forbs, and ferns. Predator excluders reduced predation by ∼40% while having no effect on nest temperatures, incubation periods, or underlying (disregarding predation) nest success. Given the results of this research, I conclude that the creation of new nesting areas could be a viable conservation tool, as females do not always return to the same nest-site area. Managers should create or maintain small patches of open-canopy habitat with reduced woody vegetation in areas that have consistent moisture from spring to fall. Increasing the availability of nesting areas may eventually lead to increases in recruitment, but if predation pressures are high, managers should also deploy predator excluders. This is the first study to examine the behavioral drivers of bog turtle nest-site selection and the efficacy of predator excluders on bog turtle nests.

▼ ENGLISH ABSTRACT: Apis mellifera, the honeybee, is regarded as the most crucial insect pollinator to South African agriculture as it is the only managed pollinator used in the pollination of commercial agricultural crops. Essential to sustaining managed honeybees is the supply of adequate and sustainable forage resources upon which managed honeybee colonies can forage throughout the year. In most instances agricultural pollination services are only required for a brief period of the year, and consequently managed honeybee colonies need to be sustained on a variety of alternate forage resources for the remaining months of the year. As an essential resource in maintaining managed honeybee colonies, honeybee forage can subsequently be linked to the maintenance of agricultural crop pollination. Exotic honeybee forage species have always been an important part of managed honeybee foraging patterns, however recent pressure to control exotic plant species in South Africa has put this type of honeybee forage under threat. This studies’ first aim was focused on identifying the historic honeybee forage use pattern in South Africa, thereby identifying which forage species have maintained managed beekeeping up until this point. A comprehensive literature review of the South African Bee Journal, dating back to the journals first publication in the 1910’s documented both the exotic and indigenous forage species that have sustained the beekeeper industry in the past. Significance ratings of individual species were determined according to the number of times a species was cited in the literature throughout the review period. Although indigenous species where cited in the literature, the predominately used forage species was found to be exotic, highlighting the role these species played in the development of South African beekeeping. Secondly, this study identifies and highlights the current honeybee forage usage pattern in South Africa. By means of a country wide honeybee forage questionnaire, honeybee forage usage patterns were determined based on forage species usage by beekeepers in different provincial regions. Important forage species were highlighted in each region on the basis of number of colonies using individual forage species. In addition to identifying current forage usage, this questionnaire was able to help estimate the number of managed honeybee colonies in South Africa at present, given that census data is not yet available. Even though there is currently a greater awareness and usage of indigenous forage species, it remains that the predominantly used forage source are exotic forage species. Whilst there appears to be a movement and awareness towards the use of indigenous forage species across South Africa, forage species usage patterns have not shift dramatically in the last century. In order to fulfill their foraging requirements, managed honeybee colonies remain heavily dependent on exotic species, especially that of Eucalyptus and certain agricultural crop species. The removal of Eucalyptus should thus just be… Advisors/Committee Members: Veldtman, Ruan, Collville, Jonathan, Allsopp, Mike, Stellenbosch University. Faculty of AgriSciences.

▼ ENGLISH ABSTRACT: Declines in natural capital, such as the degradation of ecosystems and loss of species, are the result of threats created by anthropogenic activities. The concept of sustainable development encompasses the economic and social growth of societies, with limited impacts on the natural environment. Sustainable development initiatives are being implemented in an attempt to mitigate the global decline in natural capital. Biosphere reserves, which are designated by the United Nations Educational, Scientific and Cultural Organisation’s (UNESCO) Man and the Biosphere Programme, aim to be landscape-scale examples of sustainable development. UNESCO requires biosphere reserves to submit a periodic review every ten years to ensure they are meeting their goals. This requires that that they monitor and evaluate their progress towards their sustainable development goals. Sustainability indicators are tools used to assess progress towards ecological, social and economic goals, and can thus be useful tools for biosphere reserves to ensure they are achieving their goals. The Kogelberg and Cape West Coast Biosphere Reserves are both situated within the Cape Floristic Region (CFR). The CFR, located in the South-West of South Africa, has been identified as a biodiversity hotspot owing to its high plant diversity. About a fifth of the CFR is formally protected, while about three quarters has been transformed, mainly by cultivated lands, urban areas and alien vegetation. The socio-economic dimensions of the region are also diverse. A high percentage of its inhabitants have low incomes and live in informal settlements, while a smaller percentage have high incomes and live in middle to upper-class urban areas. Biosphere reserves aim to encourage their diverse stakeholders to collaboratively develop and work towards sustainable development goals. This research project applied an action research approach. The research objectives were achieved through collaboration with biosphere reserve stakeholders. The first objective was to develop sustainability indicator sets for the Kogelberg and Cape West Coast Biosphere Reserves. Following the introduction to the research provided in Chapter 1, Chapters 2, 3 and 4 of this thesis describe the stages of the research process undertaken to achieve this objective. With the aim of investigating monitoring and evaluation within biosphere reserves, Chapter 2 presents a systematic review of the peer-reviewed and grey literature and Chapter 3 presents the results of interviews with managers of South African biosphere reserves and a web-based survey of the World Network of Biosphere Reserves. Chapter 4 describes the collaborative process of conducting local stakeholder workshops and specialist focus groups to develop sets of sustainability indicators; one set each for the Kogelberg and Cape West Coast Biosphere Reserves. The second objective was to formulate a national protocol for the development of sustainability indicators for South African biosphere reserves. This was developed through a… Advisors/Committee Members: Knight, Andrew T., Esler, Karen J., Allsopp, Nicky, Stellenbosch University. Faculty of AgriSciences.

▼ ENGLISH ABSTRACT: Reductionism, an approach to understanding complex systems based on reducing the system to its individual components and the interactions between these components, is the linear and rigid approach to traditional management and research that allows us to understand complicated systems. Yet its application to complex systems has likely added to the degradation of social-ecological systems. In recognition of this, there is currently a shift to holism: the concept that a system is greater than the sum of its components and that the system has emergent properties that are only present through the complex interactions of the whole system. The inclusion of this natural complexity within social-ecological systems is thought to promote resilience – the ability of a system to absorb shock and thus promote sustainability. However, these concepts are largely theoretical and few examples exist that demonstrate ways of transferring them to pragmatic land management. Holistic ManagementTM (HM) could potentially be such a working example. It is a decision-making framework that provides a holistic context for the adaptive management of natural resources. However, limited peer-reviewed research has been applied to this potential to promote sustainability. Thus the current study aimed to address this apparent gap by determining if HM land managers were a distinct group from non-HM (NHM) land managers in regards to their management practices and if HM land managers had a greater adaptive capacity (the management of resilience) than non-HM land managers. The study was conducted in a community of livestock farmers in the arid rangelands of the Karoo, South Africa. Data were mainly gathered through face-to-face interviews with land managers – including 20 self-defined HM land managers and 20 self-defined NHM land managers. To compare the reported management approaches of land managers, two scoring systems were developed. The HM Adoption Index measured the extent to which participants were aligned with key principles and practices of HM (including having a holistic goal, testing decisions, applying the Holistic Planned Grazing, demonstrating continuous learning and innovation). The Adaptive Capacity Index measured the extent to which participants demonstrated key traits of adaptive capacity as identified from the literature. In addition, participants were also asked to describe the strategies they apply to deal with local livestock farming challenges including parasite control, predation management and drought management. A significant difference was found between HM and NHM land managers for both the HM Adoption Index and Adaptive Capacity Index (p<0.01). The majority of HM land managers adopted ―true holistic and ―adaptive management practices (80%) while NHM land managers were mostly ―semi holistic and ―coping (65%). HM land managers also notably tended to report more innovative and environmentally aware methods in dealing with farming challenges and were more likely to be part of study groups which build social… Advisors/Committee Members: Esler, Karen J., Knight, Andrew T., Stellenbosch University.

▼ ENGLISH ABSTRACT: Soil respiration (Rs) is a major component of CO2 emissions and the global carbon balance. In the context of global change it of interest to understand seasonal patterns of RS in fynbos riparian ecosystems, particularly in invaded-riparian ecotones of these Mediterranean type ecosystems (MTE's) in the Western Cape, South Africa. Riparian ecotones are three dimensional transitional zones that provide multiple ecosystem services and functions and they act as the linkage between terrestrial and aquatic ecosystems where key ecological and geomorphological processes occur. Riparian ecotones are highly prone to disturbance, and because of this reason are also vulnerable to invasion by invasive alien plants (IAPs), notably Acacia species. Invasion by IAPs is considered one of the major threats to global change and biodiversity causing extensive ecological, economical, and social impacts. In south-western Cape, more than two thirds of the riparian environment is invaded to some extent, IAPs replacing the well adapted native species along river systems. In particular, impact of IAPs on soil respiration (Rs) may be relevant, with consequences for ecosystem function and services. Clearing of invaded riparian zones initiated by the Working for Water program has been a successful in eradicating alien plants within riparian areas even though recovery after alien clearing is lagging at many sites, and knowledge on repair of ecosystem function is lacking. Various studies have generated knowledge on carbon cycling and Rs in forests, savanna, grasslands, tundra and Mediterranean shrublands, but little is known about Rs in riparian zones, and even less about soil CO2 efflux in invaded riparian fynbos riparian ecotones. The objective of this study was to contribute to a better understanding and quantifying the effect and impact of IAPs on carbon cycling between and across riparian ecotones with different invasion status: natural, invaded, and cleared. The study areas were located in the south-western Cape and measurements of Rs, soil temperature, soil moisture, root mass, litter mass, and soil properties were carried out in riparian soils of the mountain and transitional stream longitudinal river sections, and uplands fynbos areas of six different perennial river systems. In each site, four to five transects were laid out with one sampling site of each landscape position (wet bank, dry bank, and terrestrial areas) giving a total of 12 to 15 samples per site. Soil respiration measurements were taken over a period of two years, and were done seasonally. Results from this study showed that Rs was different among seasons with highest soil respiration rates in summer. Soil CO2 efflux increased in response to warm and dry conditions during summer, while seasonal soil CO2 efflux declined in autumn and winter in response to wet and cold soil conditions. The large increase in soil CO2 efflux response to warm and dry periods when temperature was 25 to 30 °C over all riparian sites and was highest in invaded sites compared to… Advisors/Committee Members: Jacobs, Shayne M., Mantlana, Brian K., Stellenbosch University.

▼ ENGLISH ABSTRACT: Ecosystem service research has grown significantly in recent years, highlighting links between ecosystem services and human well-being. Few studies are however, geared towards providing user-friendly, user-useful and user-relevant information suitable for implementing effective local management of areas that deliver ecosystem services, resulting in a gap between ecosystem service research and management. In response to this challenge, it has been argued that in order to safeguard the benefit flows provided by ecosystems, the concept of ecosystem services should be mainstreamed into land-use (and water-use) planning and management processes. As the conservation of ecosystem services is ultimately a social process operating in a social context, understanding the complexity of the research-management interface demands input from a range of stakeholders. Thus, mainstreaming the environment into decision making requires multi-stakeholder engagement processes that facilitate the co-production and exchange of knowledge. Accordingly, through the use of a transdisciplinary, mixed method approach, this dissertation contributes to a better understanding of some of the opportunities and challenges for mainstreaming ecosystem services in development planning at a local level, using a case study in the Eden District (Eden) of South Africa. Through an extensive stakeholder engagement process which explored what the information needs, responsibilities and capacities of decision makers in Eden are, both opportunities that facilitate the integration of ecosystem service information in decision making, and challenges impeding integration, have been identified. This research found that despite a history of ecosystem service research in Eden, there has been limited integration of the concept of ecosystem services into decision-making processes driving development. Insufficient capacity, limited resources, minimal proactive planning, a weak regulatory environment, entrenched disciplinary thinking and insufficient communication amongst diverse stakeholders on the benefits of using an ecosystem-based approach remain as challenges for the mainstreaming of ecosystem services in decision making. However, strategic opportunities for mainstreaming ecosystem services into decisions regarding current and future development trajectories were also found. It was found that the development, and nurturing of transdisciplinary learning networks that are problem driven, and action oriented, using a communities of practice model of engagement, can facilitate legitimate knowledge exchange processes. In this regard, the role of individual and institutional knowledge brokers was found to be critical. It was also found that the concept of risk was useful as a mainstreaming tool in bridging the gaps between different disciplines, and between science, policy and practice. A frame of risk enabled different disciplinary and knowledge communities to participate in joint activities and discussions during which information was co-produced and… Advisors/Committee Members: Reyers, Belinda, Esler, Karen, Prozesky, Heidi E., Stellenbosch University.

▼ Soil and water conservation activities are widely practiced in all rural kebele of Raya Azebo woreda. However, little is known about the effectiveness of these practices in Raya Azebo woreda. The main purpose of this study was to assess the challenge and effectiveness of soil and water conservation in Raya Azebo woreda of Tigray. To realize this purpose for the research questions regarding the extent of implementation of the SWC practices, to document the most widely used SWC technologies to put in to practices, the effectiveness of the conservation measures in the agricultural activity of the farmers, the challenges and limitations and strength of the conservation technologies were asked. To address these questions descriptive survey method was employed. Accordingly, three rural kebele were selected using purposive sampling techniques, while 120 household head farmers selected by randomly sampling techniques, three DAs and one SWC experts and three community leaders were selected by available sampling to interview. And 15 farmers and three elders were selected randomly to employ focus group discussion and interview. To collect primary data, questionnaire with close-ended and few open-ended questions and interview were employed. The questionnaire was used to collect data from farmers, DAs and SWC experts. The informal interview, field observation and focus group discussion were conducted to cross check the information obtained through questionnaires. The data obtained quantitative were first edited, organized and tabulated and then analyzed using frequency counts and percentage. The qualitative data were first organized in to meaning full information and data were described both as expressed in the interviewees and as understood by the researcher. The result of the data analysis and interpretation indicated that the most widely SWC measures are soil bund, diversion ditch contour ploughing, grass, live fence (cactus) and other indigenous vegetation. Beside, result of the study shows that lack of commitment or motivation, lack of reliable support, lack of follow up, lack of knowledge and lack of experience of DAs and SWC experts on how to implement the soil water conservation measures are the major technical related factors which affect the implementation of SWC practices. Likewise, scarcity of facility and material to effectively implement the conservation technology, high labor requirement, more time consuming and lack of finance to construct the technology are also the other major socio-economic problems that significantly affect the soil and water conservation practices. All these are factors have their own impact on the implementation of the practices and therefore it would be difficult to achieve the expected out comes from the practices at the end. Finally, to alleviate this problem creating training, follow up, organizational support and creating awareness on the issue were suggested Advisors/Committee Members: Dessalegn Wana (PhD) (advisor).

▼ Soil and water conservation in Ethiopia was not only closely related to the improvement and conservation of ecological environment, but also to the sustainable development of its agricultural sectors and its economy at large. In the study field survey, questionnaire an interviews were conducted to collect the necessary data from 122 sample households; which were selected via simple random sampling and purposively from four kebeles of Bole Becho, Bosoke Jate, Iluna-egu-Kura, and Ielu-Iteya. The household survey questionnaire data have tabulated, and summarized by utilizing the basic statistical package for social science (SPSS). The result shows that farmers of the study area were not participating on SWC activities by their interest (voluntary) but by the force of community leader, DAs, and district administrative order they are participate on the practices. The study revealed that factors such as; slope of the area, tenure status, age, gender, education status of households, land size, lack of information, level of contact with DA, lack of awareness, length of food secured months etc; are influence the practices of soil and water conservation structure. The farmer destruct the SWC method because of searching fertile soil, to join their plot of land, for need to avail more land, to destroy hiding places of rodent pests, removing a bund about to collapse etc. They said that when the risers become big, it cover large area that makes the cropland narrower, fertile soil were used for construction, and it allows weeds to cover the farmland. Soil bund, micro basin, improved pit, terraces, water way, cut off drain, drip irrigation and compost are the soil and water conservation structure practiced by farmers and DAs on small farm land to improve the fertility of soil. As the result of the study indicates to decrease the challenges of SWC in the study area of wuchale district, the DAs, and experts of the natural resource of the area advice farmers as it is not important to destroy the terrace bench, soil bunds etc;. They advise, as it would be better to redevelop the existing terraces and supporting them with other soil fertility and SWC methods and train the farmers to change the low awareness they have on SWC practices.

▼ Understanding animal movements is fundamental to ecology and conservation, yet direct measurement of movements of birds is both challenging and costly. Raptor populations are especially difficult to monitor, but movement models can provide information toward this goal. The golden eagle (Aquila chrysaetos canadensis) in eastern North America is a species of regional conservation concern, and little is known about its population ecology, movements, or behavior. Because of their rarity and role as apex predators, improving monitoring of this small population is of great importance. Similar to using movement models to help improve monitoring, developing new methods to estimate the size of wildlife populations is also important to ecology and conservation.;In my first chapter, I simulated autumn migration of golden eagles in Pennsylvania, USA based on regional topography, eagle flight behaviors, estimated uplift, and a principal axis of migration. In total, I modeled 6,094 flight routes, averaging 2,191 (+/- 1,281; +/- SD; range: 3 - 5,373) moves. I found that 71% of my simulations intersected the Ridge and Valley physiographic province of the central Appalachians. Simulations were spatially comparable to historic, flight route data collected via telemetry. In my model, orographic uplift was significantly stronger and more frequently occurring than thermal uplift (Welch's two-sample t = -560.13, df = 43,059,702, p < 0.0001), and uplift values were not correlated with the number of simulated movements (orographic, Pearson's r = -0.015 and thermal, r = 0.003). I used output from my simulations to select sites and collect field data in new areas concentrating golden eagles on migration. This not only preliminarily verified my modeled predictions, but it also allowed me to locate new, potential monitoring sites for migrant golden eagles. I also compared output from my migration model to that of another model, to evaluate the influence of topography, spatial relationships with hawk-count sites, and role of scale in modeling migration.;In my second chapter, I evaluated the utility of hawk-count data for population size estimation of golden eagles migrating in eastern North America. I used my computer model from the first chapter to simulate migratory flights of eagles to assess what proportion of the population is available to be counted at hawk-counts in Pennsylvania, USA. I then conducted a mark-recapture analysis to estimate mean detectability of migrating eagles and mean local abundance along an important migration corridor. Finally, I used estimates of availability and detectability to adjust data from hawk-count sites to derive regional estimates of population size. Mean (+/- SD) availability of golden eagles to hawk-count sites was 0.240 (+/- 0.140; range: 0.040 - 0.440). I estimated mean detectability as 0.073 (+/- 0.010; range: 0.048 - 0.109). Previous estimates of population size for golden eagles in eastern North America were 1000 - 5000.;All of my population estimates far exceeded that of previous… Advisors/Committee Members: Todd E.

▼ Since the passage of the Surface Mining Control and Reclamation Act (SMCRA) in 1977, mined lands have generally been reclaimed to an environment characterized by severely compacted minesoils, a growth medium comprised largely of unweathered materials, and a predominance of aggressive groundcovers that inhibit native species colonization. Under these conditions, succession is arrested. Within landscapes that are fragmented by traditionally reclaimed surface mines, forest patches are smaller and forest cover on the landscape scale is reduced. As a result, forest songbirds that require large, continuous blocks of forest are negatively affected.;Some pre-SMCRA abandoned minelands contain areas of uncompacted minesoils on which hardwood forest has developed in the absence of aggressive groundcovers. Despite potential differences in tree species composition, study of the relationship between habitat structure and the avian assemblage within pre-SMCRA mineland forest could provide insight into the species assemblages that future mineland reforestation efforts might yield. Study of the reproductive success of forest songbirds within pre-SMCRA mineland forest may provide some indication as to whether this habitat is capable of sustaining breeding songbird populations. In chapter two of this thesis, I detail research in which my objectives were to: 1) examine patterns in avian assemblage structure within mineland and reference forest and to link the avian assemblage response to variables describing habitat structure and composition, and 2) contrast nest survival of Red-eyed Vireos (Vireo olivaceus) breeding within mineland and reference forest.;I conducted this research in 2011 within New River Gorge National River in southern West Virginia. I surveyed avian assemblages and sampled stand structure and composition along 28 fixed-width line transects (14 mined and 14 reference) established within four pre-SMCRA abandoned minelands and adjacent, unmined forest. Minelands within these study areas were relatively wide (80-100 m wide on average) and contained mature forest (60-65 years old) that had developed from areas of loose-dumped spoil mounded atop benches and also within outslopes.;Using an information-theoretic approach, I developed a priori models containing habitat and temporal covariates that I hypothesized to influence the nest survival of Red-eyed Vireos. Within the same study area, I monitored vireo nests within three mineland forest plots and three reference forest plots.;Ordination of avian assemblages using non-metric dimensional scaling (NMDS) showed clear discrimination between mineland and reference assemblages. Linear and surface fitting of habitat variables showed strong correlations between the ordination and groundcover gradients, but generally non-significant relationships for gradients describing forest structure. Mineland assemblages were associated with lower levels of litter cover and depth and also had lower abundance of Ovenbirds (Seiurus aurocapillus), a ground-nesting and foraging species.

▼ Several state, federal and non-profit agencies have developed collaborative goals for restoring habitat in New England and New York for a declining rabbit species, the New England cottontail (Sylvilagus transitionalis, NEC). My goal was to evaluate habitat restorations at both the local, or site, scale, and the landscape scale. In order to objectively quantify the suitability of the sites being managed, I developed a Habitat Suitability Index, based on the HSI models designed the U.S. Fish and Wildlife Service. I identified candidate habitat variables for NEC, including types of cover and refuges, and food, and then asked a panel of NEC experts to rank the importance of the candidate variables. I collected data on the most important habitat variables at 60 sites managed for NEC across New England and eastern New York. The NEC experts also ranked the same 60 sites from 1 (unsuitable) to 5 (optimal). The model was optimized to improve agreement with expert opinions for the 60 sites. Specific applications may include determining when a site is suitable for releasing translocated or captive breed rabbits, and identifying habitat features that need modification as forest succession progresses. To evaluate habitat restoration efforts at a larger landscape scale, I created metapopulation models for two management focus areas (Cape Elizabeth and Kittery-Berwick) in Maine for population viability analyses. I ran simulations to compare the relative effects of the two focus areas as well as five management scenarios. I conducted a sensitivity analysis to determine the importance of various model parameters on extinction risk. The Cape Elizabeth focus area, which has more habitat patches that are closer together, had lower extinction risks than Kittery-Berwick. Reintroductions and creating additional habitat appeared especially important in the Kittery-Berwick focus area. The simulation results were sensitive to changes in the standard deviations of the survival and recruitment rates, and the probability of catastrophic mortality, indicating that variation is detrimental to NEC metapopulation growth. Variation in weather caused by climate change may need to be mitigated by monitoring and managing NEC habitat and populations.

▼ Billions of dollars have been invested in land protection as a strategy to conserve biodiversity based on the assumption that protected areas buffer species from processes that drive extinction. Increasingly, protected area expansion and connectivity are being incorporated into climate change adaptation strategies to facilitate anticipated shifts in species ranges in response to predicted changes in temperature and precipitation. However, the effectiveness of protected areas at maintaining biodiversity, either by reducing the risk of extinction or facilitating colonization into new areas, has not been well established. In addition, the growing reliance on multiple-use protected areas that allow resource extraction, such as timber harvest and mineral mining, has raised questions about whether multiple-use protected areas are equally beneficial for long-term biodiversity conservation as more strictly protected areas that limit active resource management. In order to address these questions using repeated Breeding Bird Atlas data, I first had to confront the limitations of existing approaches to account for imperfect detection by developing a novel modelling approach to addresses the gap between requirements of other multi-season occupancy models (i.e. repeated sampling) and existing datasets. I then applied that single-visit dynamic occupancy modelling approach to Atlas data in New York and Pennsylvania for 97 species to quantify drivers of colonization and extinction while accounting for imperfect detection in landscapes that varied by type and amount of land cover and area under protection. In general, protected areas increased colonization and lowered extinction probabilities to an increasing degree as both forest cover and neighborhood protection decreased, with particular benefits for forest breeding birds. Both strict and multiple-use protected areas increased colonization and reduced extinction more for mature forest species than early forest species, with the greatest benefits accruing when forest cover was relatively low. These results provided the most comprehensive evidence to date that protected areas can facilitate species persistence by both reducing the risk of extinction and providing attractive colonization sites as species’ ranges shift and that biodiversity conservation can be compatible with renewable resource extraction.

▼ The aim of this thesis is to examine the nature of the changes that took place within paper conservation, a section of the practice/occupation of material conservation, in the United Kingdom during the period from 1975 to 2005. In the 1970s, conservation emerged as a distinct practice within the museum sector from two sources: semi-skilled cleaners and movers of art objects, and the traditional restorers of cultural objects. From then until the end of the century, it continued to grow and mature. The nature of this growth and the changes that took place within it will be modelled with the objective of enabling future changes within conservation to be evaluated. The evaluation of conservation in this manner will determine its definition as an industry. The changes will be assessed by highlighting their effect on one section of conservation practice, namely paper conservation. This practice concentrates on the conservation of cultural material created using paper, including such categories of artefacts as watercolours, fine art prints, drawings, ephemera, archival materials, books and all paper-based sculpture. During the period between 1970 and 2000, paper conservation developed from being a fledgling practice to becoming an accepted standard within the museum sector. In becoming so, it placed great emphasis on professionalism. This provided paper conservation with a template for change, a process through which it could develop and grow. Paper conservation embraced this process as a means of providing a set of standards to which it could adhere, but also as a means of garnering greater acceptability for its approach within the wider museum sector. Issues relating to the development of a profession and professionalism will be further explored as part of the literature review. Organisational change was also considered to have a relevance to the development of paper conservation, and this, too, will be explored within the literature review. Steps to professionalise conservation and subsequent changes in the wider museum sector were seen to have had the most impact on the structure of conservation. They may also have had relevance for the practice itself. Paper conservation was successful in having its occupational aims accepted throughout the museum sector, and this has further implications for those interested in researching by occupations of the professionalisation process. An understanding of the nature of this change, and how paper conservation reached its goal of acceptance for its values, is indispensable for those involved in decision-making within conservation today, and in the future. The thesis is based on an analysis of documents from the period directly relating to change within the field of conservation. It also includes interviews with personnel who were practising conservators, the providers of conservation education, and officers of the different agencies representing conservation. Research questions were formed from this analysis, and multiple case studies were undertaken to analyse these questions.

▼ Small-scale fisheries are globally ubiquitous, employing more than 99% of the world’s fishers and providing over half of the world’s seafood. However, small-scale fisheries face many management challenges including declining catches, inadequate resources and infrastructure, and overcapacity. Baja California Sur, Mexico (BCS) is a region with diverse small-scale fisheries; these fisheries are intense, poorly regulated, and overlap with foraging hot spots of endangered sea turtles. In partnership with researchers, fishers, managers, and practitioners from Mexico and the United States, I documented bycatch rates of loggerhead turtles at BCS that represent the highest known megafauna bycatch rates worldwide. Concurrently, I conducted a literature review that determined gear modifications were generally more successful than other commonly used fisheries management strategies for mitigating bycatch of vulnerable megafauna including seabirds, marine mammals, and sea turtles. I then applied these results by partnering with researchers, local fishers, and Mexico’s federal fisheries science agency to develop and test two gear modifications (i.e. buoyless and illuminated nets) in operating net fisheries at BCS as potential solutions to reduce bycatch of endangered sea turtles, improve fisheries sustainability, and maintain fisher livelihoods. I found that buoyless nets significantly reduced mean turtle bycatch rates by 68% while maintaining target catch rates and composition. By contrast, illuminated nets did not significantly reduce turtle bycatch rates across day-night periods, although they reduced mean turtle bycatch rates by 50% at night. Illuminated nets, however, significantly reduced mean rates of total bycatch biomass by 34% across day-night periods while maintaining target fish catch and market value. I conclude with a policy analysis of the unilateral identification of Mexico by the U.S. State Department under section 610 of the Magnusson-Stevens Fishery Conservation and Management Act for failure to manage bycatch of loggerhead turtles at BCS. Taken together, the gear modifications developed and tested here represent promising bycatch mitigation solutions with strong potential for commercial adoption, but fleet-wide conversion to more selective and turtle-friendly gear (e.g. hook and line and/or traps) at BCS, coupled with coordinated international conservation action, is ultimately needed to eliminate sea turtle bycatch and further improve fisheries sustainability.

▼ This study aimed at investigating the extent to which Environment Education targeted at local communities implementing wildlife Community Based Natural Resources Management (CBNRM) in South Luangwa National Park had contributed to enhancing local communities" knowledge and understanding of environmental, social and biodiversity issues to help achieve local, national and international development and conservation objectives. A randomly selected sample of 240 respondents comprising 120 Ordinary} and 120 Executive committee members from six Community Resource Boards (CRBs) participated in the study. The sample size was further broken into twenty ordinary and twenty executive committee respondents from each of the six CRBs. Two objective questionnaires were used to measure and assess community environmental and biodiversity knowledge and awareness. In addition, random interviews and focus group discussions with the sample population were used to consult institutional and community stakeholders. Results from the study show that a local community’s entire environmental and biodiversity knowledge, skills and conservation awareness was only confined to wildlife, The study found that knowledge on wildlife value and conservation was generally good and there was no significant difference in performance between Ordinary CRB and Executive Committee members. This result clearly shows that the entire local community’s environmental and biodiversity knowledge and awareness was narrowly focused on wildlife and paid little attention to broader conservation perspectives.Furthermore, the study established that the local community's knowledge and awareness of broader environmental, social and bio-diversity issues had necessarily been limited by the format under which CBNRM had been managed in Zambia and by the differential attention given to wildlife conservation policy to suit ZAWA and Slate objectives. Arising from these findings, the study concludes that generally, the majority of local communities which took part in wildlife-based natural resource management lacked the necessary knowledge and skills of social, environmental and biodiversity issues and policies to enable them adopt environmental friendly behaviour and thereby help increase their capacity to participate in meaningful conservation and achieve sustainable development. What this means is that the CBNRM approaches in practice at the time of this study (2006) did not facilitate learning and change. As this study has shown, key actors (in this case practitioners like Government and ZAWA) generally resisted modifying existing attitudes and behaviours and. instead, sought to control information, usually by resorting to highly constrained discourses and problem definitions that only served the prevailing political system. Interviews with focus groups established that the main cause for this resistance was "denial." which was found to be symptomatic of ZAWA personnel. By "denial" I refer to a situation where ZAWA personnel strongly rejected criticism for any operational errors…

After decades of research on waterbird colony persistence, or the re-occupation of a colony site in successive breeding seasons, many environmental correlates of colony persistence have been identified. However, little is understood about what truly drives waterbird colony persistence at a given site; without identifying causative factors, a full understanding of the form and function of colony site use patterns is impossible. To improve understanding of the biology of colonial waterbirds as well as conservation and management efficiency, greater research attention should be directed towards multivariate analyses of predictors of colony persistence and towards experimentation to test theoretical predictions about mechanisms determining colony site use. The former type of research allows scientists to identify the most important variables among a suite of potential predictors, while the latter is the only legitimate way to determine true causative relationships. A series of decadal surveys of Great Lakes waterbird colonies provides an opportunity to illustrate the method of multivariate analysis to inform biological and conservation understanding. I used a hierarchical occupancy model analyzed within a Bayesian statistical framework to determine the most important predictors of site colonization and colony persistence probabilities for the ten most common species in the U.S. Great Lakes colonial waterbird community. Species varied considerably in their responses to site location, human disturbance, and species richness at colony sites. Sites with large colonies and those not susceptible to flooding were most likely to be reoccupied in the following census period, suggesting that sites with these characteristics should be conservation priorities. However, the most effective conservation strategy will take advantage of knowledge about species-level variation to tailor conservation and management activities to the particular species of interest.

Cottus cognatus and Cottus bairdi are small, benthic, freshwater fish species native to southeastern Minnesota. Current conservation efforts conducted by the Minnesota Department of Natural Resources (MNDNR) have included reintroducing sculpin to rehabilitate the native fish fauna in streams historically impacted by agricultural land-use. These restoration activities have provided diverse opportunities to study aspects of sculpin ecology in southeastern Minnesota. The MNDNR reintroduction plan did not attempt to differentiate between C. cognatus and C. bairdi, in part because the two are morphologically similar and difficult to identify in the field. The two species are known to occur syntopically in some areas, and hybridization between the two has been documented. Fish survey data from the Minnesota Pollution Control Agency along with personal observation were used to identify sites in southeast Minnesota with syntopic populations. Fin clips were taken from fish in syntopic populations and genotyped using three species-specific microsatellite DNA markers. Habitat data were collected from syntopic sites to further understand conditions that allow for species co-occurrence. There was no evidence for hybridization in syntopic C. cognatus and C. bairdi populations in southeastern Minnesota, even though there was no spatial or temporal separation during breeding season. Syntopy occurred only in areas where a 1st- 2nd order spring-fed tributary flowed into a larger stream. Temperatures in syntopic locations were intermediate to temperatures recorded in allopatric locations for both species. The results of this study suggest that differences between the species limit or prevent hybridization in southeastern Minnesota. Sculpin reintroduction efforts should take into account the different preferences of each species to increase success in introduced populations. Currently, the only species used for reintroductions is C. cognatus. Research started in 2005 at the University of Minnesota examined overall ancestry, changes in genetic diversity, and fitness in reintroduced C. cognatus populations up to two generations after stocking. New introductions were conducted to examine the initial dynamics in survival and reproduction and how they affect genetic diversity. Two streams were stocked in the fall of 2007 with an equal mix of individuals from two source strains. Fin clip samples were taken from all individuals stocked into each stream, and samples from their offspring were collected the following fall. Parentage analysis requires highly polymorphic genetic markers, and microsatellite loci developed for other Cottus species were insufficient for the needs of this study. To fulfill this need, thirteen polymorphic microsatellite loci were developed from C. cognatus libraries enriched for tri- and tetranucleotide repeats. These loci had 2 to 22 alleles and observed heterozygosities ranged…

University of Minnesota Master of Science thesis. December 2009. Major: Conservation Biology. Advisor: Susy S. Ziegler. 1 computer file (PDF); vii, 182 pages.

Anthropogenic disturbances have diminished the extent of oak savannas throughout the Midwest and altered what few remnants remain. Although oak savanna restoration is of great interest to the public and reserve managers, scientists do not fully understand the intricate dynamics of the ecotone, leaving land stewards without solid restoration models. This study examined the age structure and historical fire frequency at four remnant savannas in Minnesota. A total of 846 tree cores were used to reveal temporal changes in savanna structure and 42 wedges and cross-sections were cut from oaks to date fire scars. Northern pin oak (Quercus ellipsoidalis) dominated in the southeast, grading to bur oak (Quercus macrocarpa) dominance in the northwest. Oaks were the oldest trees at each site, with relatively recent recruitment of more shadetolerant, fire-intolerant species. Few oaks predated Euro-American settlement. High bur oak establishment during the late 1800s-early 1900s was followed by a period of low oak establishment in the 1930s and 40s. Northern pin oak establishment increased rapidly in the mid-1900s, while bur oak establishment appears to have decreased, displaying a shift from bur oak dominated establishment to northern pin oak dominated establishment over the past 200 years. Whereas bur oak dominated the seedling layer, northern pin oak dominated the sapling size class. Open and healed fire scars from prescribed burns were abundant at all sites, but no fire scars predated settlement. These results suggest that many areas we currently designate as “oak savanna” may not have many (or any) oaks predating European settlement of the area due to previous land-use, climatic conditions, or species specific life history characteristics. Nevertheless, the scarcity or absence of older oaks in these areas (regardless of oak species) does not directly imply that these areas were not pre-settlement oak savanna. Anthropogenic land-use has heavily shaped the savanna community composition and structure since European settlement. Throughout Minnesota in the late 1800s, the implementation of continuous cattle grazing increased bur oak establishment and survival. Periods of logging have reduced the presence of old oaks and heavy grazing reduced oak establishment. Canopy cover has increased at all sites due to fire suppression and the maturation of earlier surges of oak establishment. The most apparent and, perhaps, threatening trend to savanna structure and composition, is the recent shift from bur oak dominated savannas to northern pin oak dominated savannas due to a combination of springtime prescribed burns, fire suppression, increasing deer populations and squirrels. A conclusive pre-settlement average fire return interval for Minnesota oak savannas could not be deduced from the fire history aspect of this study due to an insufficient number of pre-settlement fire scars.…

University of Minnesota M.S. dissertation. October 2011. Major: Conservation biology. Advisor: Dr. Peter Sorensen. 1 computer file (PDF); vii, 81 pages, appendices 1-6.

Recent studies have shown that recruitment of the common carp in many lakes of the Upper Mississippi Basin is limited to areas that experience an ecological disturbance that alters the fish community. It has been hypothesized that recruitment of carp is limited by native predatory fish and that carp are only able to recruit in habitats where these native species have been excluded due to winter hypoxia. We tested this hypothesis by comparing the survival of carp eggs and larvae in the presence and absence of native predatory fishes in three experiments. First, we sampled fish diets and carp egg abundance on a daily basis in lakes where wild carp had spawned to identify fish predators and track carp egg abundance in the environment. We simultaneously estimated the date of carp egg hatching using eggs raised in the lab at water temperatures that represented lake temperatures. We found that the bluegill sunfish was the main predator of carp eggs (94% of egg predators were bluegill sunfish), and that egg abundance declined before the estimated date of hatching in areas where bluegill sunfish were present. In our second experiment, carp egg survival was tested in the presence and absence of bluegill sunfish in the laboratory. Carp eggs were fertilized in the laboratory, placed on artificial vegetation in 70 liter aquaria that contained a bluegill sunfish or no fish, and counted twice daily until hatching. We found that the survival to hatching of carp eggs in aquaria decreased from 74% to 15% in the presence of bluegill sunfish (p-value < 0.001). In our third experiment, carp larval survival was tested in the presence of bluegill and green sunfish in the laboratory. Larval carp were raised from eggs fertilized in the laboratory until they reached their free swimming stage and introduced into 1,600 liter tanks with five individuals of a single species of predatory fish or no fish. Larvae were then sampled twice daily for two days. Both bluegill and green sunfish reduced larval carp survival to zero percent after 34 hours (p-value < 0.001). These results suggest that the bluegill sunfish is a voracious predator of the early life stages of common carp and is likely responsible for reducing the recruitment of common carp through predation on its eggs and larvae.
