Defenders in the Rocky Mountains and Great Plains
Defenders in Action: Restoring Keystone Species
Defenders keeps wildlife in the western life by restoring keystone species that have an outsized impact on their ecosystems using a broad range of conservation tools.
How We’re Helping
- Defenders helped lead efforts to reintroduce gray wolves to the Northern Rockies in 1995 and continues to work for better management and greater acceptance of these important but controversial predators, particularly as they move into new areas. Wolves play a vital role in regulating plant and animal communities by influencing the numbers and behaviors prey animals, competitors, and other species dependent on them.
- Grizzly bears were in serious trouble before they gained protection under the Endangered Species Act. Now we’re working to address conflicts as these giant animals regain parts of their historic habitat.
- Bison and prairie dogs are considered ecosystem engineers for their vigilant maintenance of our native grasslands. Prairie dogs also provide food for black-footed ferrets, swift foxes, and several birds of prey. Restoring bison and prairie dogs is key to revitalizing the Great Plains and protecting the future of other prairie species.
