Lions May Be Losing Their Reign in Uganda By Elizabeth Palermo, LiveScience Contributor | October 25, 2013 Two male African lions recline in the tall grass in Ugandas Queen Elizabeth National Park.

But the reign of the noble lion could be coming to a close in parts of Uganda, a new study suggests. One of the reasons for the lions decline in this part of Africa is poisoning by local ranchers, whose livestock are frequently killed by lions, and other human-related conflicts. Researchers from the New York-based Wildlife Conservation Society (WCS) and the University of St. Andrews in Scotland analyzed the density and population distribution of the African lion in three of Ugandas national parks. [In Photos: The Life of a Lion] In two of the parks surveyed — Queen Elizabeth National Park and Murchison Falls National Park — lion populations have decreased by 30 and 60 percent, respectively, over the past 10 years. Only in Kidepo Valley National Park, in the northeastern part of Uganda, was the number of lions found to be increasing, climbing from 58 to 132 in the last decade.

Many fear for the lions long-term chances of survival in the country and worry about the effect that declining lion populations could have on other species. Conservation areas, such as Queen Elizabeth and Murchison Falls, which formerly contained the highest biomass of mammals on Earth, depend on the delicate balance between predators and prey, James Deutsch, executive director of WCS Africa Program, said in a statement. Their loss would permanently alter two of Africas great ecosystems. But the lion-population declines in Uganda reflect a larger conservation challenge extending across the entire African continent: In the past two decades, the number of lions in Africa has declined by as much as 30 percent, and researchers believe there may be as few as 32,000 of the big cats left on the continent. Already near extinction in both western and central Africa, lions are on the losing side of a battle with locals, who view them as a threat to their livelihood. Yet, for other members of the Ugandan population, losing lions could prove to be just as detrimental as having them for neighbors. According to Andrew Plumptre, the WCS director in Uganda, lions are the animals that tourists most look forward to seeing when visiting the country. And a recent WCS survey suggests that tourists would be 50 percent less likely to visit Ugandas national parks if lions were nowhere to be seen. The study is detailed in the latest edition of the conservation journal Oryx. Follow Elizabeth Palermo on Twitter @techEpalermo, Facebook or Google+.Follow us @livescience, Facebook & Google+.
