What primary modern challenge threatens the mass movement of wildebeest populations?

Answer

Habitat fragmentation caused by human expansion, agriculture, and the installation of fences

The foremost conservation difficulty facing the famous migratory habits of the wildebeest is habitat fragmentation. This issue arises directly from human activities such as agricultural expansion and the installation of fences across ancient travel corridors. These physical barriers obstruct the animals' established routes, which can critically cut off access to necessary water sources and grazing lands. This disruption has historically led to massive die-offs, particularly during periods of drought, illustrating the severe impact of restricting their necessary movement.
