A new report concludes
that nearly half of Africa's wild lion populations may decline to near
extinction over the next 20-40 years without urgent conservation measures. The
plight of many lion populations is so bleak, the report concludes that fencing
them in - and fencing humans out - may be their only hope for survival.
The report shows that conservation costs are lower, and lion
population sizes and densities are greater, in reserves secured by
wildlife-proof fences, compared to unfenced ecosystems. Lions in unfenced
reserves were subject to a higher degree of threats from human communities,
including retaliatory killing by herders, habitat loss and fragmentation, and
overhunting of lion prey.
