My research provided new information concerning the management, ecology, and conservation of greater sage-grouse (Centrocercus urophasianus). I report the results of an experiment using strategic intensive sheep grazing to enhance the quality of greater sage-grouse brood-rearing habitat. Although forb cover, an important component of brood-rearing habitat, responded positively to the grazing treatment, the response of other habitat variables was suppressed because the plots were not protected from domestic and wild herbivores during the years following the treatments. Measurements taken in grazing exclosures confirmed that herbivory by both large and small animals had significant impacts on vegetation. However, despite the suppressed habitat response, sage-grouse preferred the treated plots over the controls. In another chapter, I modeled survival rates of sage-grouse chicks to 42-days of age. Average chick survival across my study was high (39%). Survival varied across years and was affected by demographic, behavioral, and habitat factors. The top habitat model indicated that chick survival was positively related to grass cover and was higher in areas dominated by black sagebrush (Artemisia nova) than in big sagebrush (A. tridentata). The top model with demographic/behavioral factors indicated that survival was affected by interactions between hen age and brood mixing as well as between hatch date and brood mixing. In my last chapter I report on a survey of Utah sage-grouse hunter motivations and satisfaction. In 2008 and 2009 I surveyed over 600 sage-grouse hunters in Utah to determine why they chose to apply for sage-grouse hunting permits and what factors contributed to a satisfactory hunting experience. Originally, I had hypothesized that the impending Endangered Species Act listing petition for greater sage-grouse motivated hunters to pursue the species before they lost the opportunity. This hypothesis was not supported by the data. The majority of hunters indicated that they chose to hunt sage-grouse because it was a tradition or because it provided an opportunity to spend time outdoors with family. Additionally, Utah sage-grouse hunter satisfaction was influenced by whether or not the hunter was successful in harvesting at least one bird.

Declining greater sage-grouse populations (Centrocercus urophasianus; hereafter sage-grouse) have led to increased concern regarding the long-term stability of the species. Previous research has identified factors contributing to the observed population declines. Habitat degradation and loss have been implicated as major factors in population declines. Although much is known about sage-grouse biology, more information is needed about population responses to specific management actions. This research was conducted to document sage-grouse responses to site-specific management actions. Additionally, I evaluated sage-grouse temporal and seasonal habitat-use and the comparability of techniques used by range and wildlife managers to measure vegetation responses of habitat management. Specifically, I evaluated 1) whether chemical analysis (gas chromatography) of sage-grouse fecal pellets could identify sagebrush species in sage-grouse winter diets, 2) the comparability of the line-point intercept and Daubenmire canopy cover methods for estimating canopy cover, 3) the response of sage-grouse broods to prescribed burns in a high elevation sagebrush community in northeastern Utah, and 4) the vegetation and insect characteristics of sites used by sage-grouse broods during a 24-hour period. I was able to determine wintering sage-grouse diets using gas chromatography by analyzing fecal pellets. This research also confirmed that black sagebrush (Artemisia nova) was an important component of sage-grouse winter diets in western Box Elder County and Parker Mountain populations. The line-point intercept and Daubenmire methods for estimating canopy cover are not comparable. Sage-grouse broods selected small (~ 25 ha) patchy prescribed burns in high elevation mountain big sagebrush (A. tridentata vaseyana) communities in northeastern Utah. Sage-grouse brood-site use in northwestern Utah did not differ during the diurnal hours, but nocturnal roost sites were characterized by shorter statured shrubs and more bare ground when compared to midday sites.

<p>Despite 21 years of protection, sideneck river-turtles (<italic>Podocnemis expansa</italic>, <italic>P. unifilis</italic> and <italic>P. vogli</italic>, arrau, terecay and galápago, respectively), an important food resource for riverine communities (<italic>ribereños</italic>) in the Middle Orinoco, have not recovered. To determine the most effective conservation alternative for recovery, we conducted semi-structured interviews of ribereños and determined their attitudes towards turtle conservation; we collected discarded turtle remains in riverine communities to estimate the level of turtle harvest; and constructed a population model to study the effect of reduced survival and future extraction on arrau turtle population growth. We found that ribereños blame continued commercial extraction for the lack of turtle population recovery. Ribereños have a desire to participate actively in conservation and, despite feeling alienated by governmental officials charged with protecting turtles, prefer to be included in conservation efforts. However, ribereños also fear retaliation from turtle poachers. We found widespread turtle harvest along the Middle Orinoco centered on juvenile arrau turtles, and adult female terecay and galápago turtles. In our population model, reducing harvest causes an increase in population growth. A 10% increase in survival causes rapid exponential growth in arrau turtles. The population continues to grow in over 70% of projected scenarios with limited harvest from a recovered stock. Due to the widespread distribution of turtles and their harvest, we recommend increasing ribereño participation in conservation activities, closing outsider (non-ribereño) access to the resource, increasing enforcement against illegal commercial harvest, instating possession limits for subsistence harvest, and promoting localized captive breeding of faster maturing terecay and galápago turtles to satisfy desire for turtle consumption.</p> / Dissertation

In Texas, landowner associations for the management of common-pool resources such as wildlife and groundwater have become increasingly popular. Successful management of white-tailed deer (Odocoileus virginianus) depends upon the collective decision-making of landowners. Likewise, aquifer reserves are a trans-boundary resource subject to the "rule of capture." Numerous factors may affect the success of common-pool associations, including property ownership and habitat characteristics, landowner demographics, and social capital. I used a mail questionnaire to explore the relationship between these factors and their effect on association activities and management practices for eight Wildlife Management Associations (WMAs) occurring within the Lower Post Oak Savannah (LPOS) and the Central Post Oak Savannah (CPOS). In addition, I compared responses of members of WMAs in CPOS to members of the Brazos Valley Water Alliance (BVWA), a groundwater association situated in the region. Compared to CPOS, members of WMAs within the LPOS belonged to much larger groups, were generally more recent landowners that met more often, raised more money using more funding methods, and tended to have longer association membership than CPOS landowners, yet they had lower social capital. CPOS landowners owned significantly more land and considered relaxation/leisure and hunting more important land uses than LPOS landowners. The smaller group size in CPOS may be the most important factor in building social capital. Intra-association trust was positively influenced by the longevity of property ownership, the number of association meetings, the percentage of males in the association, and other factors. Negative influences on trust included absentee ownership and Habitat Cover Index, which was a measure of the amount of wooded habitat present. In CPOS, members of the BVWA were part of a much larger, more heterogeneous, and more recently formed group than members of WMAs. They also placed greater importance on utilitarian aspects of their properties, as opposed to land stewardship for conservation as practiced by members of WMAs. If associations are kept small ( < 50) with more frequent meetings, greater social capital and information sharing may be achieved, which may lead to increased land stewardship practices. However, landowners may be motivated more by their shared values independent of any benefit from their association.

M. Tech. Nature Conservation / Ticks are blood feeding external parasites of mammals, birds, and reptiles throughout the world. Tick infestation is considered to be one of the main constraints to successful game ranching in southern Africa. Several blood parasites are transmitted by ticks and have been incriminated as the cause of death in several wildlife species Ticks thus affect wildlife and domestic animal management worldwide, with approximately 850 species of ticks having been described The aim of the thesis is to collect and describe fully the nature and extent of the tick cohort of a semi-intensive and control free game ranch in the Limpopo Province of South Africa farm and to establish the environmental management effects on tick abundances and species.

Social perspectives on natural resources management have become an increasingly valuable part of natural resources management decision making, especially at the policy or governance level. However, due to the range of social contexts that can exist around management questions, not every technique for incorporating stakeholders into management is suited for every management problem. My research examines the social landscape around chronic wasting disease (CWD) management on the Canadian prairies in order to identify a way forward for stakeholder involvement in CWD management. CWD is a prion disease that results in neurodegeneration and death in cervids. CWD has the potential for broad social impact because it infects elk and deer, species which are both hunted and ranched. Furthermore, management and monitoring efforts in free-ranging cervids frequently incorporate hunting activity. Q methodology was used to survey stakeholders in Saskatchewan and Manitoba and synthesize perspectives about stakeholder understanding of CWD as a problem and preferences for potential solutions. The perspectives that emerged emphasized the importance of increasing knowledge about CWD and a generalized trust in government management, coupled with a desire for stakeholder consultation under the auspices of government leadership. I found that CWD management may not be ready for stakeholder spearheaded management activity due to ambivalence and uncertainty among stakeholders, but stakeholder involvement in CWD management can still offer valuable insight for managers. This is especially notable in light of the recent loss of Saskatchewan’s CWD monitoring program.

Wildlife management in Moryambique has had a troubled history. The end of civil war and installment of a democratic Government provided opportunity to redefine policy and implementation of conservation. Weakened by civil strife and with wildlife decimated in many areas, Government sought approaches to conservation that would promote participation by investors and civil society, particularly rural communities. The intention is to acknowledge the rights of rural people to resources and the benefits that can accrue from their use. Partnerships are seen as a way in which Government can bring the required financial and human resources to bear whilst at the same time engendering positive attitudes to conservation in general, and to policy in particular. The purpose of this research is to examine, using two case study conservation areas, the consequences of Government's attempts to implement its policy. The philosophical basis for the research is that policy reform and implementation should be envisaged as a complex system comprising many interactions and that when this complexity is not acknowledged and addressed systemically, it predisposes the process of policy reform and implementation to failure. A principal cause of failure is considered to be that assumptions are not made explicit and this results in development and application of an approach that does not accord with reality. Further, because of the networked nature of the system, failure at one point can be magnified as its consequences are propagated through the system. A conceptual framework for policy reform and implementation is developed. This exposes some critical assumptions about Government's capacity to implement policy and the ways in which implementation is experienced by stakeholders, especially local communities. Context is provided by tracing the evolution of approaches to conservation in Moryambique from the pre-colonial era to the present. The findings are that Government does not have the capacity to implement its conservation policy and this is shown to have serious implications for how local people perceive and respond to Government approaches to conservation. Causal factors are analysed and assessed. It is concluded that the process of policy reform and implementation is complex but that a systems approach provides a simple and easily comprehended way in which this complexity can be interpreted and taken into account with potentially very significant benefits. Perceptions are shown to be a powerful determinant of response to policy reform and implementation. As these are commonly a basis for destructive tensions between parties, it is suggested that research directed at defining the principles that should underpin management of perceptions and tensions should be encouraged. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2004.

Research has shown that trust is essential to the functioning of co-management. This is especially true in the Territory of Nunavut where wildlife is an integral part of the lifestyle and culture of Nunavummiut (the people inhabiting Nunavut). In Nunavut, wildlife is managed by a co-management board situated in between federal, territorial, regional, and community governments and organizations. This research explores Inuit attitudes and trust in managing wildlife as part of a co-management system in the Kivalliq Region of Nunavut, Canada. Interviews were conducted in the communities of Igluligaarjuk (Chesterfield Inlet), Tikirarjauq (Whale Cove), and Qamani’tuaq (Baker Lake). Even now with the 1993 settlement of the Nunavut Land Claims Agreement (NLCA) and the implementation of a public government in 1999, there is documented evidence that beneficiaries of the NLCA are dissatisfied with wildlife management decisions and do not trust the governing process of co-management. In this study, participants specifically indicated dissatisfaction with regulations and outcomes of current polar bear co-management. It has been predicted that conflicts specific to polar bear management could lead to regulations being ignored or even defied and endanger the entire system of wildlife co-management. Results from this research indicate that dissatisfaction over decisions involving polar bears is dominantly compartmentalized towards the outcomes of polar bear management and does not necessarily apply to the broader system of wildlife co-management. Therefore, in the Kivalliq Region, predicted impacts of dissatisfaction over polar bear co-management may apply directly to the polar bear co-management system but likely not the wildlife co-management system generally. This study provides a forum where Inuit trust in the wildlife co-management system is documented and I hope it will contribute to an increased understanding of Inuit goals in wildlife management and to the discourses on co-management in Nunavut.

The southwest Yukon social-ecological system (SES) is marked by complex changes, including a climate induced directionally changing landscape, an increasing shift away from traditional subsistence lifestyles, and changing species composition. The addition of “new” ungulate species through human and non-human introductions has spawned many management questions. This study developed qualitative scenarios through a participatory process, utilizing scientific and traditional knowledge from within the social-ecological system’s local context. The study worked with local management groups to address two main objectives: 1.) Collaboratively envision alternate future scenarios with management groups from which to collaboratively develop management goals for wood bison, elk, and mule deer to cope with the changing social and ecological landscape of the southwest Yukon and 2.) Discover resource managers’ and local stakeholders’ perceptions of scenario planning as a method identify wildlife management goals. A series of three workshops with the Alsek Renewable Resource Council, the Yukon Wood Bison Technical Team, and the Yukon Elk Management Planning Team addressed the first objective, while two surveys addressed the second objective. Major findings included southwest Yukon-specific wildlife management goals and considerations for using scenario planning in a wildlife management context. The scenarios themselves warn of plausible events that might unfold, such as novel disease and pest outbreaks. Several participants mentioned that the value attributed to different species will change based on scenario context. This prompts warnings for wildlife managers not to “shut the door” on a species today that may be highly valuable for solving food security challenges of the future. Findings suggest that one of scenario planning’s most significant contribution is a forum for people to share perspectives and develop trust and understanding of one another. All participants valued the holistic and long-term thinking aspects of scenario planning, seeing it as a complementary tool to enhance existing planning processes. Major resource management plans and/or resource development projects in the future should consider using a scenarios approach to better articulated goals in terms of whole system impacts.
