    Our Species

    Migratory birds, resident wildlife, and endangered and threatened species can be found at Imperial National Wildlife Refuge. The refuge contains backwaters that provide key habitat for wildlife. Because of the river's life sustaining water, wildlife thrives in this environment where temperatures reach 120 degrees in the summer and the average rainfall is two inches per year.
