“…Woodroffe et al (2005) pointed out that wild dogs attack more sheep and goats in northern Kenya and our findings are consistent with this. Wildlife population densities tend to be lower outside the Serengeti National Park than inside the Park and to decrease with increasing distance from the Park (Setsaas et al, 2007), TABLE 2 Total number of attacks by carnivores on cattle Bos primigenius and on sheep Ovis aries and goats Capra aegagrus hircus in the two study areas (Fig. 1) because of legal and illegal hunting, human encroachment and human activities in general Nyahongo & Røskaft, 2011).…”

During 2007-2009 we conducted a survey of attacks by wild carnivores on the livestock of the Maasai and Sonjo tribes in the eastern Serengeti ecosystem of northern Tanzania. Local enumerators systematically recorded incidents of carnivore predation on livestock and their data were quantified by us, with the aid of District Game Officers or trusted local people. The annual rate of attack by African wild dogs Lycaon pictus was significantly higher (1.42 animals per 1,000 livestock) in the Sonjo tribal area than in the Maasai tribal area (0.72 animals per 1,000 livestock). In the Maasai tribal area there was a significant amount of predation by leopards Panthera pardus and spotted hyaenas Crocuta crocuta. In both tribal areas sheep Ovis aries and goats Capra aegagrus hircus were subject to predation more frequently than cattle. Attacks on livestock by wild dogs occurred most frequently in the afternoon and evening, whereas other carnivores generally attacked livestock at night. Sheep and goats were most frequently attacked by most carnivores during the long rainy season. Cattle Bos primigenius were most frequently attacked by wild dogs and leopards during the long dry season and by lions Panthera leo during the long rainy season, whereas spotted hyaenas killed cattle most frequently during the short rainy season.

“…Poaching has previously been known to occur in the Grumeti, Ikorongo and Western part of SNP, where the majority of poachers are located (Holmern et al 2004;Kidegesho 2010;Metzger et al 2007;Setsaas et al 2007). Poaching in West could therefore possibly explain the increased FGM levels in these areas.…”

“…If the visibility did not allow observation at from this point, the distance was decreased, but not so much that it initiated a flight response. The flight response and flight distance of impala can be attributed to predator avoidance and is described in Setsaas et al (2007). I recorded data on the distance between the road and the nearest animal by a rangefinder (Leica Rangemaster 900), road category, the number of cars, grass quality and group size.…”

PrefaceThe background for this study is the imminent threat of global species decline, which I believe deserve immediate attention to enable us to preserve the Earth's biosphere and ensure that future generations will inherit a functioning planet. It is in direct association with the principles of the Convention on Biological Diversity (CBD) of the United Nations, which aims to conserve biological diversity, ensure sustainable use and an equal sharing of our resources.

“…It has become increasingly apparent that hunting has wider ranging effects than solely reducing densities of ungulates (Setsaas et al 2007;Mysterud 2014;Festa-Bianchet 2017). Selective removal of individuals may change aspects of social organization and dispersal rates (Milner et al 2007;Allendorf and Hard 2009;Averbeck et al 2010;Borg et al 2015, Leclerc et al 2017, while hunting disturbance can induce escape movements and temporary home range displacement (Kamei et al 2010;Grignolio et al 2011;Thurfjell et al 2013;Jarnemo and Wikenros 2014).…”

Challenges and science-based implications for modern management and conservation of European ungulate populations

et al. 2017

View full text Add to dashboard Cite

Wildlife management systems face growing challenges to cope with increasingly complex interactions between wildlife populations, the environment and human activities. In this position statement, we address the most important issues characterising current ungulate conservation and management in Europe. We present some key points arising from ecological research that may be critical for a reassessment of ungulate management in the future.
