Research overview: woody encroachment and savanna change for African cats

Rising carbon dioxide, altered rainfall, and changed fire and grazing regimes are driving woody plant encroachment into many African savannas, reshaping habitat for cats and their prey. This overview surveys how bush encroachment alters the open grassland that cheetahs and lions use for hunting, affects prey communities, and changes visibility and hunting success. It reviews the interacting roles of climate, herbivory, and fire suppression in driving the shift. The synthesis frames woody encroachment as a subtle but landscape-scale habitat change distinct from outright clearing, explaining why some savanna specialists may lose suitable open habitat to thickening vegetation even as total tree cover increases, complicating simple narratives about deforestation and cats.
