Wild Grizzly Bear Recovery in North America

Grizzly bear recovery in Greater Yellowstone and other ecosystems demonstrates both conservation success and ongoing human-wildlife conflict challenges.

Key Facts

Grizzly bears in the Greater Yellowstone Ecosystem recovered from approximately 150 to over 700 individuals
They were delisted from Endangered Species Act protection multiple times with court reversals
Human-caused mortality including livestock depredation response, vehicle collision, and illegal killing is the primary mortality source
Grizzlies require vast territories - males may use 1,000+ km2 - making connectivity critical
Whitebark pine nut loss from white pine blister rust is reducing an important fall food source
Young male grizzlies dispersing from established populations are most vulnerable to conflict mortality
Coexistence tools including electric fencing and bear spray significantly reduce conflict mortality

Welfare Considerations

Grizzly bears involved in livestock conflicts are often destroyed after first or second incidents. Bears attracted to human food sources through poor storage become conditioned and are killed. Young dispersing males navigating human-dominated landscapes face car strikes, illegal shooting, and management kills as they seek new territories. Non-lethal coexistence tools that prevent conflicts protect both livestock producers and bear welfare simultaneously.

What You Can Do

Support Greater Yellowstone Coalition and other organizations working on grizzly connectivity
Advocate for adequate habitat corridor protection for young bears dispersing from recovery areas
Support electric fencing programs for beekeepers and livestock producers in grizzly habitat
Carry bear spray in grizzly habitat and practice deployment to prevent defensive attacks
Secure attractants including garbage, bird seed, and pet food in bear-proof containers
Oppose grizzly delisting without adequate population and connectivity protections in place
