(The World Conservation Congress, 2012, issued a formal resolution Res 5.022, specifically supporting mammal conservation initiatives
in these regions, http://www.iucn.org/about/work/programmes/global_policy/gpu_resources/gpu_res_recs/) (2) Hunting areas are extensive, so the fate of lions depends on how well user-communities manage them. The same principle applies to lions within protected areas, with responsibility falling on protected area managers to secure these populations. Finally, lions also occur well beyond protected areas, and how well one manages lion-human conflict will determine persistence there. Yet, conflict outside protected areas can affect lion persistence within (Woodroffe and Ginsberg 1998). Good protection within a protected area is not sufficient if there CA4P supplier is unrelenting killing of lions outside it. (3) Central Africa may have sizable lion and prey populations, but they are poorly known, even by African standards.
(4) That said, independently verified census data, using statistically repeatable techniques are the rare exception, not the rule, across even relatively well-studied East and Southern Africa. The situation is particularly acute for Tanzania, which holds a large fraction of the world’s lions. (5) Repeated PI3K inhibitor mapping of areas which have at least the potential for lions because of their low human impacts may CHIR 99021 provide the only quantifiable measures of how savannah Africa is shrinking from the lion’s viewpoint. This is necessary, but definitely not sufficient. The lack of repeated, statistically credible lion counts, for well-defined areas is a striking omission, one that must be rectified if we are to assess not only the trends in lion numbers, but our success in reversing
their declines. Acknowledgments This project was supported by National Geographic Society’s Big Cats Initiative.
