Are elephants flagships or battleships? : understanding impacts of human-elephant conflict on human wellbeing in Trans Mara District, Kenya

Nyumba, Tobias Ochieng January 2018 (has links)
This thesis examines the impacts of human-elephant conflict on human wellbeing and the implications for elephant conservation and management in Trans Mara District, Kenya. The District comprises communal lands bordering the world-famous Masai Mara National Reserve in southwestern Kenya. Trans Mara supports a range of land use types and provides refuge to one of Kenya’s large elephant population comprised of over 3,000 transient and 500 resident animals. This study used interdisciplinary methods to gain insights into the nature and consequences of conflict on the wellbeing of communities living with elephants. In particular, I used a combination of existing wellbeing indices and a set of indicators developed through consultations with local communities in TM to measure impacts of HEC on specific wellbeing domains. The results show that elephants still use the communal lands in Trans Mara but are increasingly restricted to the riverine forest remnants in central Trans Mara. However, there was no evidence of a further decline in the elephant range. Instead, this study points to a shift in elephant range against a background of increasing human settlement, land sub-division and agricultural expansion. The wellbeing of Trans Mara residents comprised eight indicators. Human-elephant conflict negatively affected peoples’ wellbeing, but the impacts were limited to certain dimensions. Elephants affected school-going children within elephant range. Attitudes towards elephants and its conservation in TM were influenced by the location of human residence relative to elephant refuge, diversity of income sources, and age and gender. Finally, conflict mitigation in Trans Mara is still elusive and challenging, but opportunities exist to develop simple and dynamic mitigation tools. The findings of this study have important implications for the future of elephant conservation in the face of competing human needs, both in Trans Mara District and elsewhere in Africa.

Nesting Ecology, Survival, and Home Range of Wild Turkeys in an Agricultural Landscape

Delahunt, Kenneth Scott 01 May 2011 (has links)
Most research on Eastern wild turkeys (Meleagris gallopavo silvestris) has occurred in extensively forested habitats atypical of midwestern landscapes. I studied the ecology of female wild turkeys in a portion of southern Illinois consisting of an agricultural matrix interspersed with forest, and grassland cover types. I quantified causes of hen and nest mortality, nesting habitat variables, nesting rates, nest success, clutch and brood sizes, and incubation length. I also examined daily nest and weekly hen survival rates, and hen and brood home ranges and habitat selection. Sixty-four hens were radiomarked during 2008-10. Predation was the primary cause of nest mortality (80.5%) and hen mortality (100.0%). Coyotes (Canis latrans) were responsible for 40.3% of nest mortalities and 42.8% of hen mortalities, whereas bobcats (Lynx rufus) caused 42.8% of hen mortalities. Weekly survival rates were 98.7 and 98.6% for adult and juvenile hens, respectively. Seasonal survival rates for adult hens varied from 68.7% during breeding to 88.9% during winter. Most hens (98.5%) made a first nest attempt, 75.6% of hens attempted a second nest, and 8.0% of hens attempted a third nest. Mean clutch size was 12.4 ± 0.4 (SE throughout) during the first nesting attempt and 9.6 ± 0.6 during the second nesting attempt. The mean incubation length of successful nests was 31.1 ± 0.8 days. Mean nest success was 19.8%, producing 11.3 ± 3.3 poults/per
