Counting kings: How annual lion surveys reveal the health of Africa’s protected areas

On a dawn drive through a savannah reserve in Zambia, a ranger slows the truck and points to a faint trail in the dust. It is not the spoor of an antelope or a stray cow. It is the print of a lioness moving with her cubs toward a waterhole. In another era, such sightings were a matter of pride and anecdote. Today, they are data points. Each paw print, each camera image, and each confirmed pride member feeds into a growing network of annual lion surveys across sub-Saharan Africa. Those surveys are telling managers and funders something that budgets and patrol logs cannot: whether protected areas are holding their ground or slipping. Lions are more than charismatic megafauna. They are architects of ecosystem dynamics in the savannah food web, shaping the balance of species and the landscapes they inhabit. One apex predator can influence hundreds of plant and animal species by shaping grazing pressure, predator competition, and the movement of prey. When lions vanish, the balance frays. Herbivores boom or crash, vegetation shifts, and even fire regimes change. Reintroductions rarely restore the original equilibrium. In ecological terms, the “king” is a keystone.

Unlike rare endemics confined to a single park, lions occur naturally in a number of Africa’s large protected areas. Unlike elephants, whose numbers can mask habitat degradation, lions decline quickly when prey is overhunted or corridors are severed.…This article was originally published on Mongabay
