WILDLIFE in the WEST
Threatened and endangered species in the West cover the gamut. They are bighorn sheep and wolves. They are sage-grouse and salmon. They are pygmy rabbits and spotted frogs.
Our wildlife cases wield the Endangered Species Act, the National Environmental Policy Act and others to halt habitat destruction – unchecked grazing, industrial development, mining exploration, obsolete dams – wildlife in the West face these and many other threats daily.
As climate change and human activities cause the loss and fragmentation of habitats, our work becomes increasingly vital. We strive to protect and boost diminishing wildlife populations – from the mighty bighorn to the fragile frog.
