Only 48 bird species regularly nest along the river, while others use the river as a migration corridor or as overwintering habitat.

Because of the aridity, many animal species rely on protected migration corridors during droughty conditions.

Environmentalists expressed concern about butterfly migration corridors and the future of two species of local wildcats, the ocelot and the jaguarundi.

Pronghorn migration corridors are threatened by habitat fragmentation and the blocking of traditional routes.

The project aims to ensure long term survival of viable conservation reliant populations of elephants in their natural habitats by protecting the elephants, their habitats and migration corridors.
