Researchers working in Benin’s Pendjari National Park reported some promising news for West African leopards: Density rose from 2017 to 2023.West Africa’ leopards are regionally endangered, with just 354 remaining across the region.Pendjari National Park sits within the W-Arly-Pendjari Complex, a large transboundary conservation landscape encompassing national parks, hunting reserves and buffer zones that in recent years has been infiltrated by non-state armed groups operating in the Sahel. While conservation efforts in the national park are working, the security crisis remains a major threat.

It’s been difficult to monitor West African leopards in Benin’s Pendjari National Park: It’s a large wilderness area, situated within a hotspot of armed conflict. The park is among the last strongholds for this geographically distinct leopard population — but a recent study shared hopeful news.

Leopard density in the park increased over a six-year period, according to a study published in the journal Global Ecology and Conservation. The park has been managed by the nonprofit African Parks since 2017 in partnership with the government — and this conservation effort seems to be working.

“It’s a win,” said study lead author Marine Drouilly, a biologist with Panthera, the global wild cat conservation non-profit.
