“…Impala trophy size trends declined significantly over time and these are comparable to findings observed in Zimbabwe [30] and South Africa [25]. The contribution of illegal hunting [59] on the declining trophy size trends may be minimal given that subsistence hunters kill indiscriminately and do not select for trophy size [76,77]. Although trophy sizes for the three ungulates were slightly smaller than expected [32], we note that the habitats and feed quality in Tanzania are different from those found in Zimbabwe.…”

“…In the present study, greater kudu and sable populations did not change regardless of the period, possibly due to people preferring impala. This has also been observed in western Tanzania, where most local people are known to hunt small herbivores [59]. We could not get information on illegal hunting activities and patrolling efforts from Cawston Ranch records for this period of turmoil and land reform (2002)(2003)(2004)(2005)(2006)(2007)(2008).…”

“…Generally, documented declines in wild herbivore populations are caused by droughts [54,55], diseases [56,57], illegal hunting and overharvesting [46,[58][59][60] and habitat loss [61]. In Katavi National Park and Rukwa Game Reserve in western Tanzania, illegal hunting was found to be a greater source of mortality than predation, disease, or legal hunting [59]. However, most of these studies were based on large open areas where management interventions are not as targeted as in closed, privately managed game parks such as Cawston Ranch.…”

“…Also, the available literature are sporadic and biased towards certain geographic locations and protected ecosystems particularly Serengeti (e.g. Hofer et al 2000, Loibooki et al 2002, Marealle et al 2010 and Katavi (Caro 2008, Martin andCaro 2012) leaving other equally impacted ecosystems, such as Tarangire, Mikumi, and Ruaha, under-researched. Illegal hunting is a big problem in the Simanjiro plains, a seasonal refuge for wildlife dispersing from Manyara and Tarangire National Parks (Rija 2009).…”

Emerging issues and challenges in conservation of biodiversity in the rangelands of Tanzania

Tanzania rangelands are a stronghold for biodiversity harbouring a variety of animal and plant species of economic, ecological and socio-cultural importance. Efforts to protect these resources against destruction and loss have involved, among other things, setting aside some tracks of land as protected areas in the form of national parks, nature reserves, game reserves, game controlled and wildlife management areas. However, these areas and adjacent lands have long been subjected to a number of emerging issues and challenges, which complicate their management, thus putting the resources at risk of over exploitation and extinction. These issues and challenges include, among other things, government policies, failure of conservation (as a form of land use) to compete effectively with alternative land uses, habitat degradation and blockage of wildlife corridors, overexploitation and illegal resource extraction, wildfires, human population growth, poverty, HIV/AIDS pandemic and human-wildlife conflicts. In this paper, we review the emerging issues and challenges in biodiversity conservation by drawing experience from different parts of Tanzania. The paper is based on the premise that, understanding of the issues and challenges underpinning the rangelands is a crucial step towards setting up of plausible objectives, strategies and plans that will improve and lead to effective management of these areas. We conclude by recommending some proactive measures that may enhance the sustainability of the rangeland resources for the benefit of the current and future generations.

“…Lion presence was far lower outside and within the periphery of the national park than in the park centre (Kiffner et al, 2009), despite no parallel edge effect in herbivore abundances (Kiffner et al, 2012). Yet even in the central part of KNP there has been a probable decline over the last 15 years (Caro, 2008(Caro, , 2011, likely driven by overly high tourist hunting quotas, Sukuma lion killing, and perhaps a lowered prey base resulting from bushmeat exploitation and water diversion (Caro, 2008;Caro et al, 2013;Packer et al, 2011;Martin and Caro, 2013).…”

From avengers to hunters: Leveraging collective action for the conservation of endangered lions

a b s t r a c tFewer than 40,000 lions are left in Africa, perhaps 40% of which reside in Tanzania. Lions in East Africa are commonly killed in situations where they prey on livestock, either to retaliate for loss or avert future attacks. Among the Sukuma, Tanzania's largest cattle-raising ethnic group, tradition allows a lion killer to visit households, perform a special dance, and demand rewards for ridding the area of a potentially dangerous predator. Here we document how this tradition of gift-giving provides sufficient economic incentive that lion killing continues to persist in the face of a near absence of livestock loss from lions. Contemporary lion killers no longer act as avengers, retaliating for loss or averting future attacks, but as hunters, pursuing non-threatening lions far from residential and grazing areas and often inside protected areas. Our study reveals that Sukuma householders are less likely to reward a lion dancer if they have received frequent visits from dancers (indicative of donor fatigue) and if they perceive change in motivation from avenging to hunting. These findings suggest that it may be possible to reduce illegal killing of lions by working through Sukuma institutions responsible for collective action within the local community, and to remove the economic incentive for killing non-problem lions.
