African Lion (IMAGE) Wildlife Conservation Society Caption A female African lion peeks through the leaves of a tree in Queen Elizabeth National Park. Lions have been decreasing in some areas of Uganda (particularly the national park areas) by more than 30 percent over the past 10 years due to poisoning by local cattle herders and other human-related causes.
