Why are we really killing iconic wildlife mass migrations with fences?
Land conversion is accelerating collapse of ungulate (hooved mammals) mass migrations. Moreover, settlements, roads, railway lines and gas pipelines are expanding in wildlife ranges, blocking migratory routes.
This accelerates extinction of mass migrations. Fences obstruct wildlife movements and largely caused the collapse of the last three ungulate mass migrations in the Kenya Kajiado and Narok Counties. Removing and regulating fences and building underpasses or overpasses along barriers crossing migration routes and land use planning may help save ungulate migrations.
