Mortality Patterns of Asian Elephants in a Region of Human–Elephant Conflict

Many wildlife species suffer from human–wildlife conflict, especially crop-raiding. Long-term analyses of mortality patterns are needed to assess the efficacy of management strategies that address this issue. We report mortality patterns from necropsies of 498 Asian elephants from 2009–2018 in an area of northwestern Sri Lanka. Deaths were lowest in July and highest in October, a period of peak crop availability. Most (about 70%) deaths were human-related, and males were killed in these incidents more frequently than females. As gunshot deaths decreased, other forms of human-related deaths increased. Additionally, causes of death differed between districts, with more intentional human-related mortality observed in the district with the highest percent of protected land. These results highlight the importance of understanding the long-term spatial and temporal variation in wildlife mortality to effectively address human–wildlife conflict. © 2021 The Wildlife Society.     

Effects of human–carnivore conflict on tiger (Panthera tigris) and prey populations in Lao PDR

Unique to South-east Asia, Lao People's Democratic Republic contains extensive habitat for tigers and their prey within a multiple-use protected area system covering 13% of the country. Although human population density is the lowest in the region, the impact of human occurrence in protected areas on tiger Panthera tigris and prey populations was unknown. We examined the effects of human–carnivore conflict on tiger and prey abundance and distribution in the Nam Et-Phou Louey National Protected Area on the Lao–Vietnam border. We conducted intensive camera-trap sampling of large carnivores and prey at varying levels of human population and monitored carnivore depredation of livestock across the protected area. The relative abundance of large ungulates was low throughout whereas that of small prey was significantly higher where human density was lower. The estimated tiger density for the sample area ranged from 0.2 to 0.7 per 100 km². Tiger abundance was significantly lower where human population and disturbance were greater. Three factors, commercial poaching associated with livestock grazing followed by prey depletion and competition between large carnivores, are likely responsible for tiger abundance and distribution. Maintaining tigers in the country's protected areas will be dependent on the spatial separation of large carnivores and humans by modifying livestock husbandry practices and enforcing zoning.     

Conservation and Wildlife Management in South African National Parks 1930s–1960s

In recent decades conservation biology has achieved a high position among the sciences. This is certainly true of South Africa, a small country, but the third most biodiverse in the world. This article traces some aspects of the transformation of South African wildlife management during the 1930s to the 1960s from game reserves based on custodianship and the “balance of nature” into scientifically managed national parks with a philosophy of “command and control” or “management by intervention.” In 1910 the four British colonies had formed the Union of South Africa, and by the 1920s there was wide acceptance of national parks, a development influenced by their success in the United States. It was not, however, until after the Second World War, that management of the expanding conservation estate altered from a rather unsystematic laissez faire variety, into more scientifically informed management practices with an efficient bureaucracy in charge. This was achieved by modifications in organizational structures and institutional cultures initiated by a change of government in 1948 which, this article argues, impacted in turn on wildlife management and shaped and professionalized many aspects of that field science. “Management by intervention” was the hallmark of South African wildlife and conservation biology from the 1960s until recently, when there have been shifts towards “adaptive resource management” in a period of further change in the country’s politics.     

Human–wildlife conflict in Mhokwe Ward,Mbire District,North-East Zimbabwe

This research investigates the economic and social aspects of human–wildlife conflict (HWC) in Mhokwe, Mbire district, Zimbabwe. Data were collected through key informant interviews and a questionnaire survey. Most households in Mhokwe rely on crop and livestock production, and hence, HWC is an important factor affecting livelihoods. More than 60% of respondents experienced problems with lions (Panthera leo Linnaeus), spotted hyaenas (Crocuta crocuta Erxleben), armoured bush crickets (Acanthoplus speiseri Brancsik) and quelea birds (Quelea quelea Reichenbach). Other problem animals included elephant (Loxodonta africana Blumenbach), vervet monkey (Chlorocebus pygerythrus Cuvier), kudu (Tragelaphus strepsiceros Pallas), chacma baboon (Papio ursinus Kerr), bushpig (Potamochoerus porcus Linnaeus) and common duiker (Sylvicapra grimmia Linnaeus). Few incidences of conflicts were reported for hippopotamus (Hippopotamus amphibius Linnaeus), side-striped jackal (Canis adustus Sundevall), porcupine (Hystrix africaeaustralis Peters), nile crocodile (Crocodylus niloticus Laurenti), African wild cat (Felis lybica Forster), African python (Python sebae Gmelin) and guinea fowl (Numida meleagris Linnaeus). Livestock and crop losses were US$45,285 and US$57,541 in 2013 and 2014, respectively. Despite the losses, most respondents had positive attitudes towards wildlife. Construction of strong kraals and implementation of integrated pest management (IPM) can contribute to conflict reduction.
