▼ Ethiopia is facing rapid deforestation and degradation of land. To overcome this serious problem, the Government of Ethiopia has taken different measures such as policy interventions, conducted studies, and implemented massive soil and water conservation (SWC) and capacity building programs. The study analyzed normalized difference vegetation index as indicator of vegetation restoration/degradation, in South Wollo, Northern Ethiopia. The study analyzed inter-annual normalized difference vegetation index (NDVI) changes using MODIS data. The analysis was based on data from 2000 to 2011, by classifying in to three parts, i.e., from 2000 to 2005, 2006 to 2011, and 2000 to 2011 for the dry seasons. Between 2000 and 2005 degradation was greater than restoration but the rest two section (2006 to 2011 and 2000 to 2011) show general vegetation restoration. The statistical result indicated that in the period the area shows significant restoration and degradation at 90% and 95% confidence interval. The study also shows vegetation dynamics across the slope by using cross tabulation method. Average 2000 NDVI cross tabulation indicated that more vegetation dynamics is shown in lower (0-10) slope interval but little vegetation dynamics in higher slope interval. However, vegetation restoration is slightly greater than degradation in higher slope interval. On the other hand Average 2005 show almost balanced vegetation degradation and restoration between 0 and 10 degree slope but in higher slope interval i.e.40 degree and above vegetation restoration higher than degradation. Average 2011 cross tabulation also the same with earlier but in lower slope area vegetation degradation mach greater than restoration. Generally in higher slope area vegetation restoration greater than degradation that indicates it is not accessible for the expansion of Agriculture. On the other hand in lower slope area vegetation degradation greater than restoration which indicates the area more accessible for the expansion of agriculture.

▼ Sustainable management of river networks is an important topic in hydrology today. Rivers and streams are a significant source of drinking water, as well as energy production and other human valued services. Spatial and temporal patterns of flow regimes have a significant impact on ecological and anthropogenic uses of fresh water within entire river basins. Developing tools for management of streamflows hinges on a deep understanding of the hydrologic form and function at the basin scale, and the interplay between the key driving processes. This study is centered on providing a process-based description of flow regimes and their spatial variability, with the purpose of developing tools for catchment-scale management of streamflows and studying ecologically relevant processes. Simple methods that allow a spatially explicit characterization of flow regimes with limited data and calibration requirements are extremely valuable for efficient management of water resources in data scars regions. In order to meet these research goals, a modeling method was developed in this thesis for the prediction of streamflow regimes, based solely on catchment-scale climatic and morphological features. The method was tested in eleven test catchment distributed evenly in the United States, east of the rocky mountains. Considering the minimal data requirements (rainfall, potential evapotranspiration and digital elevation maps), the method was capable of capturing the patterns of observed streamflows reasonably well in all cases. This method was then expanded and applied point-wise along the river network of a test basin in north eastern Switzerland. A custom geo-database and a Web GIS platform were created for the management of data and model application. Predicted values of relevant flow statistics were validated at six subcatchment outlets, where discharge data was available, with satisfactory results. Strong seasonal signature of rainfall was identified as the dominant driving force of flow regimes. The seasonal variability of the streamflows showed a complex pattern, influenced by climatic gradients and by the increasing variability of hydrologic response observed at larger scales. The modeling method and data management framework presented here offer a novel and robust approach for assessing the spatial patterns of streamflows based on limited information. The spatial and temporal variability of river flows bear important influence on ecological processes at the reach and basin scales. In this thesis, the effect of streamflow dynamics on riparian vegetation growth was studied using a lumped stochastic framework which explicitly incorporates the randomness of exposure and submersion periods implied by the streamflow variability, and links such a randomness to climatic and landscape properties. The framework was applied to the terminal reach of two catchments characterized by contrasting flow regimes. The results illustrated the role of vegetation specific traits and water availability as limiting factors, and flow regime… Advisors/Committee Members: Mario (Dir.), Daniel (Codir.).

▼ Vegetation diversity has long been known to enhance natural pest control at both the local and landscape level. However little is known about the characteristics of this vegetation that promote/shelter more natural enemies and suppress pests. The main aim of this thesis was to examine how characteristics of common non-crop vegetation influence the abundance, diversity and association of natural enemies residing in two different agricultural systems (canola fields and vineyards). These crops were chosen to contrast annual and perennial cropping systems. Canola, grown directly after a pasture phase of a field, is Australia’s most important oilseed crop. Pressure on invertebrates may be greater due to level of disturbance; in contrast, vineyards are often surrounded with various types of vegetation which may enhance invertebrate abundance. To explore this aim, the effect of within crop, non-crop vegetation (grass strips within canola crop) on abundance of pests and natural enemies in the crop was examined. Invertebrates were collected across grass-canola transects in two fields planted to canola with unsown grass strips at intervals. Sampling with pitfall traps and vacuum sampling was completed to collect ground dwelling fauna during two sampling periods: post sowing and post emergence of canola seeds. Invertebrates collected were categorized mainly into two groups: pests and natural enemies. Abundant pests in the canola fields were red legged earth mite, Halotydeus destructor; blue oat mites, Penthaleus spp. and lucerne flea, Sminthurus viridis. Natural enemies considered were spiders (Araneae), predatory mites (Acari), predatory beetles (Coleoptera) and parasitoids (Hymenoptera). In general more predators and parasitoids were found in the unmown grasses of grass strips and more pests in mown sections of the grass strips and overall pests were more abundant in the crops than in grass strips. Vegetation types may have different influences on the biota that reside within them. Thus the effectiveness of different vegetation types in promoting conservation biological control was assessed at vineyards with two types of non-crop habitat: adjacent- grass with and without trees. Invertebrates were sampled in the canopy with sticky traps and on the ground with pitfall traps at 40 sites from six different vineyards at Yarra Valley (Victoria) for five consecutive months from bud burst to harvest (October through February). Collected invertebrates were classified as natural enemies and other invertebrates since none of the invertebrates collected are considered as pests in vineyards. The most abundant natural enemies were generalist predators (spiders and predatory beetles Coleoptera: Carabidae and Staphylinidae) and parasitoids (Hymenoptera), lacewings (Neuroptera), hover flies (Diptera: Syrphidae) and other predatory Diptera (Asilidae, Empididae and Tachinidae), predatory thrips (Thysanoptera), predatory Hemiptera, and ladybird beetles…

▼ Evapotranspiration (ET) is a significant hydrological process. It can be studied and estimated using remote sensing based methods at multiple spatial and temporal scales. Most commonly and widely used remote sensing based methods to estimate actual evapotranspiration (AET) are a) methods based on energy balance equations, b) vegetation coefficient based method and c) contextual methods. These three methods require reflectance and land surface temperature (LST) data measured at optical and thermal portion of the electromagnetic spectrum. However, these data are available only for clear sky conditions and fail to be retrieved under overcast conditions creating gaps in the data, which result in discontinuous of AET product. Moreover, energy balance equation based methods and evaporative fraction (EF) based contextual methods are difficult to apply over overcast conditions. In this context, vegetation coefficient based (Tasumi et al., 2005; Allen et al., 2005) and microwave remote sensing based methods can be applied under cloudy sky conditions (Sun et al., 2012), since microwave radiations can penetrate through clouds, but these data are available at coarse resolution. In the vegetation coefficient method temporal upscaling can be avoided. Therefore in this research vegetation coefficient based method is employed over Cauvery basin to estimate daily AET for clear and cloudy sky conditions. Required critical variables for this method such as reference evapotranspiration (ETo) and vegetation coefficients are obtained using LST and optical vegetation indices for all sky conditions. In this study, all sky conditions refer to both clear and cloudy sky conditions. Most important variable for estimation of ETo using radiation and temperature based models is air temperature (Ta). In this study, for better accuracy of Ta, two satellite based approaches namely, Temperature Vegetation Index (TVX) and Advance Statistical Approaches (ASA) were evaluated. In the TVX approach, in addition to traditional Normalized Difference Vegetation Index (NDVI), other vegetation indices such as Enhanced Vegetation Index (EVI) and Global Vegetation Moisture Index (GVMI) were also examined. In case of ASA, bootstrap technique was used to generate calibration and validation samples and Levenberg Marquardt algorithm was used to find the solution of the models. The better of the Ta results obtained out of these two approaches were employed in the ETo models and are referred as Ta based ETo models. Instead of Ta, processed LST data obtained directly from the satellite (Aqua/Moderate Resolution Imaging Spectroradiometer (MODIS)) was applied in the ETo models and these are referred as LST based ETo models. These Ta and LST based Hargreaves-Samani (H-S), Makkink (Makk) and Penman Monteith Temperature (PMT) models were evaluated by comparing with the FAO56 PM model. Additionally, simple LST based equation (SLBE) proposed by Rivas et al. (2004) was also examined. Required solar radiation (Rs) data for ETo estimation was obtained from Kalpana1/VHRR… Advisors/Committee Members: Nagesh Kumar, D (advisor).

▼ The thesis examines various aspects of vegetation dynamics and change on subantarctic Macquarie Island over the ten years 1980 to 1990. The island is basically an elongated plateau surrounded by steep coastal slopes 100-250 meters in height. The major vegetation type on these slopes consists of tall tussock grassland dominated by the tussock-forming grass Poa foliosa, with the tall herb Stilbocarpa polaris an important accompanying species. The behaviour and distribution of these two species in the coastal slope vegetation under various disturbance conditions through time, forms the major focus of this study. The longitudinal observations of the study (involving longterm re-sampling through time) also allow the testing of an existing model of revegetation patterns on disturbed coastal slope sites which was based on a set of latitudinal observations (once-off "spatial" sampling of time-sequence data from a series of differently aged sites). These latitudinal observations were taken at the beginning of the 1980-1990 study period. The timing of the study coincides with the first ten years after myxomatosis was first introduced into the feral rabbit population in 1978- 79, substantially reducing rabbit numbers. The effects of grazing on the coastal slope vegetation since the introduction of rabbits in the 1850's appears to have been substantial, although until recently little documented. Landslipping is also a common disturbance factor affecting the coastal slope vegetation. Changes in the vegetation of 27 sites on areas affected by landslipping, rabbit grazing or a combination of both, were studied over the 10-year period by monitoring of fixed plots. This study was complemented by a broadscale study of vegetation change over a five kilometer section of the coastal slopes through comparison of aerial photographs taken at the beginning and the end of the study period, and by a study of changes in a series of paired quadrats in relatively undisturbed vegetation over the same period. A study of seasonal growth and dieback patterns of Stilbocarpa polaris over a twelve month period, and analysis of a series of observations on grazing patterns prior to 1980, provided additional insights into behaviour of Stilbocarpa polaris and effects of grazing on the coastal slopes. Through these means, the effects of the various disturbance factors on the vegetation dynamics can be inferred. Since 1980 there has been an overall increase in abundance of Poa foliosa and Stilbocarpa polaris, especially the former, on the coastal slopes. This can be linked to the substantial reduction of rabbit numbers after 1978-79 to a level amenable to control, but not eradication, by myxomatosis. It could also possibly be linked to climatic warming. Vegetation succession on areas disturbed by landslipping or rabbit grazing will eventually progress to a Poa foliosa-dominated vegetation with Stilbocarpa polaris as a co-dominant or subsidiary 4.ominant, in the absence of further grazing disturbance and/ or slope instability. Continuation of selective…

▼ The rate of recovery on barrier islands after hurricanes is not well understood, because the majority of studies have focused on the geomorphic impact of storms on barrier islands. Dune vegetation recovery is a vital component of barrier island recovery because it promotes the deposition of the sand required for dune stabilization. Despite a paucity of studies that quantitatively characterize vegetation recovery following hurricanes, Escambia County, Florida, was advised to spend nearly half a million dollars on revegetation efforts following relatively minor damage during the 1998 hurricane cycle. This research seeks to better understand that process by quantifying changes in vegetation extent between 1994 and 2010 on Santa Rosa Island, Florida following Hurricanes Opal and Ivan. Multispectral airborne imagery is used to analyze vegetation patterns and recovery. If no vegetation is present, sediment will not be deposited consistently. The clumps of plants collect sand in their wind shadows that grow and merge to create dunes. Changing patterns of vegetation distribution over time are examined in a geographic information system. The Verhulst logistic growth model is used to describe post-hurricane vegetation recovery. The logistic growth models results indicate that given twenty-five years of observed data, vegetation recovery occurs in approximately ten years on the Fort Pickens portion of the island and after fifteen years on the Santa Rosa Island portion of the island. The Verhulst model reveals that vegetation growth rates (r) are higher in the overwashed transects. This is most likely the result of variations in the plant species found in an overwashed transect. The transects in which vegetation spread to a greater portion of the transect (K) were more commonly collision dominated. This was probably because greater portions of these transects were less vulnerable to disturbance from run-up. Results suggest that there is a time lag between beach recovery and dune recovery that can be explained by vegetation recovery. This scale dependence will be affected by high-magnitude, high-frequency disturbances because it increases the chance that the vegetation will not have recovered before the next disturbance event thereby changing the dominant geomorphic regime. Fourier transformation reveals that there was an alongshore variation in the vegetation coverage before and after Hurricanes Opal and Ivan that corresponds to the frequencies of the ridge and swale bathymetry, around 1400 meters.

▼ Climate variability in New Zealand (34-47°S), a long, narrow continental strip straddling the mid-latitudes of the Southern Hemisphere, results largely from the interplay between sub-tropical and sub-Antarctic atmospheric and oceanic circulation systems. Despite their importance to present-day New Zealand climate, these hemispheric-wide systems have only recently come under the spotlight of paleo-climate investigations with most attention having traditionally been centred on reconstructing climate trends. This PhD adopts a broader approach to climate reconstruction, by developing and comparing two new pollen-climate reconstructions from New Zealand (38-42°S) and one from Patagonia, Southern Chile (43°S). At each site, paleo-climate interpretations are based on the changes in climate-sensitive plant indicators. The influence of hemispheric atmospheric circulation on New Zealand climate history is assessed by: (1) comparing New Zealand climate/vegetation trends with published proxies from low- and high-latitudes, and (2) comparing New Zealand reconstructions with the Patagonian record. Finally, a multi-millennial pattern of Southern Hemisphere circulation over the last 14,000 cal yr BP (calendar years before AD 1950) is outlined. The first record presented is a 16,000-year temperature reconstruction from a small alpine lake in South Island, New Zealand (41°S), based on pollen and plant macrofossils. Climate variations are interpreted from the relative abundance of lowland and highland vegetation. The results include a lifting of the altitudinal forest limits attributed to warming pulses between 13,000-10,000 cal yr BP and between 7000-6000 cal yr BP, and a decline of lowland relative to upland forest taxa interpreted as cooling trends between 10,000-7000 cal yr BP and over the last 3000 years. The second record gives 15,000-year temperature and precipitation reconstructions from a peatbog in northern New Zealand (38°S), based on pollen and charcoal analysis. Temperature changes are assessed based on two quantitate reconstructions, whereas precipitation trends are inferred from variations in arboreal taxa with different drought tolerances. A long-term warming is inferred between 14,600-10,000 cal yr BP. Persistent dry conditions are recorded between 12,000-10,000 cal yr BP, followed by a long-term wet period between 10,000-6000 cal yr BP. The last 7000 years feature a long-term drying trend that culminates with persistent drier conditions over the last 3000 years. The third record provides a 16,000-year reconstruction from a small lake in Northwestern Patagonia (43°S), based on pollen and charcoal analysis. Climate conditions are inferred from the relative variations of pollen types with distinctive climate tolerances and complemented with changes in fire activity. These variations are in turn interpreted as resulting from changes in the position and/or strength of the Southern Westerly Winds (SWW). Cold and moist conditions attributable to stronger/northward-shifted SWW winds are observed between 16,000-13,600 cal yr… Advisors/Committee Members: Newnham, Rewi.

▼ The 'treeless plains' is a colloquial name given to low lying undulating areas on Melville and Bathurst Islands which support a variety of shrubland and low open-woodland plant communities. The major aim of this thesis is to describe the vegetation of the plains and elucidate which environmental factors are determining the vegetation patterning, particularly across the forest plains boundary. Numerical classification of vegetation survey data is used to define seven plant communities on the plains and adjacent forests. These communities differ floristically and/or structurally to other northern Australian plant communities, and show similarities to vegetation which is classified under the general headings of 'heath' and 'savanna'. The major environmental correlate differentiating the treeless plains communities from each other is wet season inundation. Secondary variation within the plains vegetation and between the vegetation of the plains and adjacent open-forests is associated with changes in several inter-correlated edaphic factors, including texture and moisture. Detailed descriptions of the vegetation patterning across forest plains boundary shows that there is an abrupt structural change, with a distinct 'ecotone' or 'transition' zone between the forest and the plains. This structural change is accompanied by a gradual or 'ecoclinal' shift in composition of the understorey. A parallel study of environmental factors showed a gradational change in conditions with the plains occurring on soils which are generally sandier, less fertile, drier and possessing higher water tables than adjacent forest areas, and other red earth soils supporting eucalypt forests and woodlands in northern Australia. Eucalypt seedling growth was significantly retarded when subjected to flooding in pots, but the flooding tolerances of species tested did not correspond to their relative ecological ranges observed in the field. It was concluded that the deep sandy soils on the plains drain excess water rapidly at the end of the wet season and thus do not maintain water tables at levels high enough to prevent tree growth even in very wet years. Field measurements showed that although surface soil moisture levels on the plains were severely depleted during the dry season, there appeared to be adequate moisture at depth to support tree growth throughout the year. Field plantings and associated pot trials supported this contention by showing that seedlings could grow under conditions of higher moisture stress that those recorded in the field at the end of the dry season. There were significant differences in levels of nutrients, particularly magnesium, calcium and aluminium, across the forest plains boundary. Pot trials showed that eucalypt seedlings grew slower in plains soils compared to forest soil and that the growth differential was not due to differences in mycorrhizal fauna. The growth of transplanted eucalypt seedlings appeared to be suppressed by the forest overstorey, possibly due to competition for moisture. Seedling growth…

▼ The machair systems of the Outer Hebrides of Scotland are renowned for the diversity and conservation value of their plant communities. However, machair systems have a restricted distribution and are prone to disturbance from both anthropogenic and environmental sources. The effects of two major anthropogenic and environmental disturbances (agriculture and burial by wind-blown sand) on the Kildonan and Drimsdale machair systems on South Uist, and the dynamic responses of machair vegetation to these human and natural agencies were described and quantified. The investigated machair systems comprised a diversity of sand dune, grassland and marginal vegetation types which were spatially distributed along a primary environmental gradient of soil organic matter, soil moisture and soil pH. Vegetation types influenced by the effects of cultivation, notably potato-bed successions, abandoned field systems and fallow areas were also a conspicuous component of the Kildonan and Drimsdale machairs. Re-vegetation following cultivation occurred primarily through vegetative processes. Sexual reproduction via seed within different machair vegetation types was limited. The numbers of viable seeds recorded from machair seed banks ranged from 7 mˉ² soil in foredune vegetation to 58 mˉ² soil in newly-ploughed cereal land. Densities of viable seeds recorded from the machair seed rain ranged from 2 mˉ² soil in the dune slack to 24 mˉ² soil in a potato patch, fallow for two years. These values represent the first estimates of the size of machair seed budgets. Glasshouse-based burial experiments examined the effects of inundation by sand on four machair vegetation types. Foredune grassland, dune slack, three-year fallow grassland and unploughed grassland vegetation exhibited the capacity to survive and re-emerge from both intermittent and single depositions of sand. In terms of effects on plant frequency, intermittent burial by five depositions of 1cm of sand was more damaging than a single deposition of 5cm. However, all vegetation types responded to both intermittent and single burial events primarily through a change in the number of individual plants, rather than through a change in the number of plant species. Five different responses to burial by sand were identified for machair species. The suspension of photosynthetic activity and the maintenance of a low dark respiration rate were identified as important physiological responses to burial. Photosynthetic activity of machair vegetation was resumed on denudation, indicating the existence of an elastic physiological response to burial. Ecological processes in the dune slack habitat and the responses of slack vegetation to its dynamic environment were subtly different to those characterizing the other investigated sub-communities. These differences were attributed to the fact that machair slacks are characterized by an historical ecology distinct from that of other areas of the machair system. It is suggested that the formulation of effective management plans and conservation strategies…

▼ Numerous studies have addressed the role of stream geomorphology on vegetation distribution. These studies have shown that channel morphology, including depositional and erosional processes, influence vegetation colonization. However, few studies have addressed the impact of vegetation on the geomorphic processes of streams. Vegetation has the ability to stabilize channel banks and alter stream hydrology and stream power. Little research has addressed the impact of invasive vegetation and its ability to change river channel processes. My research addresses the impact of the highly invasive Phalaris arundinacea and quantifies its influence on the stream channel form of the Sprague River, Oregon. I conducted field research that included root density and root strength surveys to determine the below ground influences of vegetation in terms of added bank cohesion provided by the invasive and two similar native species: Eleocharis palustris and Carex vesicaria. To ascertain differences between the species above ground characteristics and influences, I measured stem density and elasticity to calculate their roughness (Manning's n) and determine their potential impact on stream velocity. Finally, I used these vegetation characteristics to model stream velocity, water depth, and bed shear stress within the 2-D model MD-SWMS. Differences in root size were significant with C. vesicaria having the largest root diameters, largest root area ratio, and largest bank cohesion provided by roots. This was followed by the invasive and then E. palustris. E. palustris had the highest stem density, followed by C. vesicaria and P. arundinacea. The invasive had the highest stem stiffness. E. palustris was associated with the highest roughness value, closely followed by the invasive and C. vesicaria. Using modeling I found the presence of the invasive increased velocity compared to E. palustris and increased bed shear stress compared to C. vesicaria. Therefore, changes in species composition, such as a shift from either of the natives to the invasive, could affect channel morphology over time. By comparing the impact of this invasive to that of native grasses and sedges, this research provides insight into how further spread of the invasive may affect the Sprague River and other riparian ecotones.

This study aims to characterize the variation in stomatal conductance and leaf water potential of corn plant in height over time on a diurnal time-scale and on a seasonal time-scale, under well-watered and water stressed conditions. An additional objective was the development of a protocol for plant-water relation measurements in radar experiments. Field experiments were done to measure the leaf water potential by conducting pre-dawn measurements three times a week, evening measurements once a week and a mid-day measurement in the beginning and at the end of the growing season. The stomatal conductance was measured multiple times per day for three days a week, given that there was no precipitation. As the research is part of a larger project, additional hydrological data, soilmoisture data and sap flow data were collected. For the stomatal conductance a clear variation over height was observed. This variation was caused by limited solar radiation for the lower leaves. The leaves that received full solar radiation had clear diurnal cycle in stomatal conductance and a high variation in stomatal conductance. In water-stressed conditions, it is expected to see a change in stomatal behaviour in these leaves. For the leaf water potential, no values were reached that have been connected to water stress in the literature. Also, no water stress coping mechanisms were observed in the corn. From this it can be concluded that no water stress took place during this experiment for the days on which data was collected. In the leaf water potential data a clear influence of the soil water potential was observed. For the leaf water potential, no values were reached that have been connected to water stress in the literature. Also, no water stress coping mechanisms were observed in the corn. From this it can be concluded that no water stress took place during this experiment for the days on which data was collected. In the leaf water potential data a clear influence of the soil water potential was observed.
