Modern predators : the science, sovereignty, and sentiment of wildlife conservation in Zambia.

Godfrey, Elizabeth 03 March 2014 (has links)
This dissertation presents the suspicions and tensions encountered during ethnographic fieldwork with (what I call) the Predator Project Zambezi (PPZ), a WWF-funded research and conservation organization based in Zambia. It extrapolates the broader contexts of this uneasiness and situates it within global conservation discourses. The distrust that manifests between the wildlife authorities in Zambia, the residents of rural areas, and PPZ epitomizes postcolonial contentions over state sovereignty and the continued hegemony of Euro-American environmental ideologies. Moreover, the objective perspective that is claimed by PPZ as a scientific organization is challenged through analysis of its daily epistemic contradictions. In this ethnography, I show how the priorities of conservation institutions as communicated through PPZ ultimately work to arrest the post-colonies in a continuous state of catching up to the eco-modern condition that is ascribed to the global North.

The ecology and conservation biology of the Black-cheeked Lovebird Agapornis nigrigenis in Zambia.

Warburton, Louise Sarah. January 2003 (has links)
This study was undertaken to investigate the ecology of the Black-cheeked Lovebird Agapornis nigrigenis in the wild. Prior to this study little was known about the ecology of this parrot or other members of the genus Agapornis. The Black-cheeked Lovebird is classified as Vulnerable and has suffered a severe population decline and reduced distribution, from which, for largely speculative reasons, it has never recovered. The overall aim of this project was to elucidate the basic biology of the Black-cheeked Lovebird and determine the conservation actions which are necessary to conserve the species in the wild. Fieldwork was conducted across the species' range in south-west Zambia over twenty-two months between May to December 1998; March to December 1999; and February to May 2000. An education project focussing on Black-cheeked Lovebird conservation was conducted with local schools, villagers and Zambia Wildlife Authority scouts during September 2001. Historical records pertaining to distribution of the Black-checked Lovebird, both within and beyond Zambia are few, anecdotal and often discredited, and it is suggested that the species should be considered as endemic to Zambia. Within its core range the species has a clumped and localised distribution, associated with Mopane woodland and permanent water sources. Two sub-populations occur and appear to be distinct. Black-cheeked Lovebirds were most active, in the early morning and late afternoon, forming the largest daily flocks sizes during these times, which correlated with drinking and feeding activities. The smallest flock sizes occurred when roosting. Overall flock sizes were significantly larger during the dry (non-breeding) season. Black-cheeked Lovebirds were observed feeding on 39 species. Food items included seeds, leaves, flowers (especially nectar), fruit pulp, invertebrates, bark, lichen, resin, and soil. Various foraging techniques were used. Terrestrial foraging was dominant, with little temporal or spatial variability. Arboreal foraging in plants varied seasonally and by availability. Feeding preferences were not specialised and there was no dependence on a limited food resource. Black-cheeked Lovebirds fed on two agricultural crops. There was no evidence to suggest an extended foraging range during the crop-ripening season, or the reliance on crops for survival. The crop-ripening season coincided with the lovebird breeding season. The species is widely perceived as a crop pest, with 18% of seed heads of millet crops suffering more than 20% damage during the ripening season. Local farmers attempted to protect their crops in a variety of ways, however, these were largely ineffective and rarely lethal to lovebirds. The importance of elevating local tolerance for the species through education programmes is highlighted. This study presents the first collection of breeding data on the species. Breeding occurred from midlate January to early May. A single clutch was raised by most pairs per breeding cycle. Seventy-eight nests were found and characteristics measured. Fidelity to nest-sites is suspected. Although breeding behaviour was non-cooperative most nests were found in a loosely clumped distribution. No nesting requirement appeared to be in limited supply, or had reason to affect the population's reproductive output. Behavioural data on nest location, building, defence and predation are presented. In addition courtship, copulation, parental care and juvenile behaviours are reported. Data on clutch size, laying intervals and hatching success with captive birds are included. One nestling tested positive for Psittacine Beak and Feather Disease Virus (PBFDV). Other observations suggest PBFDV is present in the wild population. Implications for research and conservation are discussed. Black-cheeked Lovebirds roosted inside naturally formed cavities in live Mopane trees. Roost cavities were found in a loosely clumped distribution. No roosting requirement appeared to be in limited supply. Black-cheeked Lovebirds are highly dependent on surface water supplies and need to drink at least twice daily. The lovebirds are highly cautious drinkers that will not drink if the water resource was actively disturbed by humans or livestock. Water availability is a limiting factor to the Black-cheeked Lovebird. The gradual desiccation of its habitat appears to be the major cause behind the reduction of occupancy within its small range. Over the last 45 years (1950 - 1997) the annual rainfall in the Black-cheeked Lovebird's habitat has decreased resulting in further reduction of its already highly localised distribution increasing the species dependence on artificial water supplies. The conservation management of the species should be prioritised towards maintaining and creating water resources with minimal external disturbance; upholding the wild-caught trade ban in the species, continuing environmental education with local schools promoting lovebird conservation, and monitoring populations through dry season water source counts. / Thesis (Ph.D.)-University of Natal, Pietermaritzburg, 2003.

Ecology, conservation and management of the black lechwe (Kobus leche smithemani) in the Bangweulu Basin, Zambia

Kamweneshe, Bernard Mwila 22 February 2007 (has links)
The black lechwe Kobus leche smithemani) is an antelope that belongs to the family reduncinae. Its current population is confined to the Bangweulu Basin in the northern Zambia. This research was undertaken to assess its current population status, the sex and age ratios, carrying capacity of the flood-plain where it occurs and its maximum sustainable yield. The study also estimated its potential sustainable off-take and looked into the links that exists between wildlife and socio-economics in order to demonstrate the views of local people on current wildlife management and utilisation. Historical records suggest that these antelopes were more widely spread and more numerous earlier last century. Until the 1930s the population may have numbered over 250 000. Records indicate major population decline during the first half of last century and therefore called for a quick management action. The population decline was thought to be caused by over-hunting and habitat change caused by an increase in water levels in the swamps. Aerial surveys during the 1950s suggested less than 20000 and by 1970 only 16 000 lechwe were counted from the air. From 1988-1996, ground surveys were undertaken with a four-wheel drive vehicle, on motor bike and on foot. A series of aerial censuses was also conducted during October, at the height of the dry season when the lechwe are relatively evenly distributed in the swamps, thus facilitating the use of stratified random sampling method. A fixed wing cessina 182 was used throughout the surveys. The study revealed that black lechwe is a highly prolific and resilient species. Its population has great potential to increase if given adequate protection and proper managed. Mating takes place on shallow flood-plains between November and April, but peaks in March. Receptive females leave their herds to join small breeding ground comprising few dominant males, which may be likened to leks formed by some other antelopes. The population of lechwe is currently maintained around 30,000. The sex ratio of the species is equal to unity and the age ratio was estimated at 3 : 1. The entire Bangweulu wetlands can sustain a population of at least 160 000 lechwe. A sustainable off-take of 6 000 individuals per annum was recommended. Black lechwe being an endemic species to the Bangweulu Basin is important for the economy of the country and the rural population. The study has revealed that local people are keen to participate in conserving it together with other species and the habitat as long as they are clear about benefits that they will gain from their effort. / Dissertation (MSc (Wildlife Management))--University of Pretoria, 2007. / Centre for Wildlife Management / unrestricted
