Wildlife
Below are just a few of the keystone wildlife species we fight to protect. We work to protect healthy landscapes that these and so many other species need to survive. Among the threats to these species' habitats are domestic livestock grazing on the public lands, clearcutting of old growth forests, rampant off-road vehicle abuse, damming of our wild rivers, irresponsible energy development and mining on public lands and global climate change.
As you're browsing through the species, notice the links to the cases we are working on concerning each species.
