How Old Is Grizzly 399
Grizzly 399 is a wild grizzly bear monitored in the Greater Yellowstone Ecosystem. Public records and bear monitoring agencies list her as an adult female born in the mid-1990s, making her one of the oldest known reproducing grizzlies in the region. Her documented history is widely cited by wildlife agencies and conservation organizations focused on bear management. Data on her age comes from long-term monitoring and tagging efforts shared in official reports and public summaries available at https://www.nps.gov/yell/learn/nature/bears.htm.
Researchers track her age through ear tags, GPS collars, and annual observations during bear monitoring seasons. Her longevity is considered exceptional for a wild grizzly, where average lifespans are often shorter due to habitat pressures and human interactions. Conservation groups reference her case when discussing the importance of protected corridors and food sources in bear habitats. Her story is also highlighted by wildlife education platforms that publish bear profiles and updates at https://www.bear.org/.
Grizzly 399 Age and Reproductive History
Documented Birth Years and Cubs
Grizzly 399 has produced multiple litters over her lifetime, with documented cubs observed in various monitoring seasons. Wildlife biologists record her reproductive events in annual bear management reports, noting the number of cubs per litter and their survival rates. These records help agencies assess the health of the grizzly population and the effectiveness of habitat protections. Her reproductive data is included in long-term studies shared with the public through agency websites and research summaries at https://www.fs.usda.gov/.
Her older cubs, now independent adults, have been spotted in adjacent ranges, extending her genetic legacy across the ecosystem. Monitoring teams use remote cameras and field observations to confirm identities of her descendants. Public wildlife databases and educational platforms publish these findings to support transparency in bear management. Specific population data and monitoring updates are available through state wildlife agencies at https://wildlife.utah.gov/.
Conservation Status and Public Interest
Why Grizzly 399 Matters
Grizzly 399 is frequently cited in discussions about grizzly bear conservation, human-wildlife coexistence, and habitat connectivity. Her high visibility along park roads and in documented encounters has made her a symbol for non-lethal bear management strategies. Public interest in her story has driven funding and attention toward bear-resistant infrastructure and education programs. Her case is referenced in policy briefs and conservation reports published by environmental organizations at https://www.defenders.org/.
Legal protections for grizzly bears in the Greater Yellowstone area have been shaped in part by data from long-monitored individuals like Grizzly 399. Federal and state agencies use her monitoring records to inform decisions about hunting regulations, habitat designations, and conflict mitigation. Her story is also covered in journalism and educational content that links bear conservation to broader ecosystem health. Recent legal and policy updates related to grizzly bear management are tracked by conservation law centers at https://www.ecelaw.org/.
