Grizzly bear deaths in the Greater Yellowstone Ecosystem have reached an unprecedented modern-day high, exceeding earlier records from 2024 and 2025. With a few weeks remaining before denning, 81 bears have died this year, rising to 82 with an unrecorded case. This trend follows a historical pattern of high mortalities, with 1972 seeing 120 bear deaths post-closure of Yellowstone’s garbage dumps.
Despite recovery efforts, including reduced conflict with humans, bear deaths have escalated. Wildlife managers acknowledge this increase but do not see it as alarming. The record 82 deaths this year outstrip previous highs, with the most significant incidents involving livestock and accidental deaths. The Interagency Grizzly Bear Study Team’s data shows these figures.
Grizzly bear fatalities in 2026 mainly stem from human-related causes, consistent with historical norms. Key factors include cattle depredation, accidental encounters, and natural causes. Illegal poaching also contributes significantly. The numbers reflect an ongoing struggle to manage bear populations effectively.
Matt Gould from the Interagency Grizzly Bear Study Team notes these yearly fluctuations as natural and significant. “Drawing conclusions from a single year is challenging,” he stated, emphasizing long-term monitoring’s role in understanding population dynamics.
Though 2026 was challenging for grizzlies, adult female bears within the “demographic monitoring area” largely avoided mortality. Wyoming Game and Fish’s Dan Thompson highlighted this, adding, “There’s enough recruitment in the population to compensate for this mortality level.”
The grizzly bear population remains stable despite high mortality rates, though it reflects growing densities along the ecosystem’s periphery. Former Grizzly Bear Recovery Coordinator Chris Servheen observed that natural bear-on-bear deaths have spiked, “Grizzlies self-regulate at high densities,” he said, noting this influences subadult survival rates and population growth.
The ongoing debate on delisting grizzlies from their threatened status continues, with the U.S. Fish and Wildlife Service working on rules to shift management to states. Past delisting attempts have been overturned due to ecological concerns. Despite high mortality figures, these may not heavily influence delisting decisions. However, critics like Servheen worry about state influence on bear management.
