Summary

These data are preliminary or provisional and are subject to revision. They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS nor the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data. The Interagency Grizzly Bear Study Team (IGBST) evaluates mortalities for population segments within the DMA by deriving estimates of total mortality for independent-age (2 years or older) females and independent-age males, including estimates of unknown/unreported mortalities based on Cherry et al. (2002). We then determine the total annual [...]

Purpose

Under the 2017 Revised Demographic Criteria for the Yellowstone Ecosystem, which were amended to the Grizzly Bear Recovery Plan (USFWS 1993, USFWS 2017), the Interagency Grizzly Bear Study Team is tasked with documenting grizzly bear mortalities in the Demographic Monitoring Area (DMA) and evaluating mortality levels (Demographic Recovery Criterion 3). At the 2008 fall meeting of the Yellowstone Ecosystem Subcommittee of the Interagency Grizzly Bear Committee, the request was made for IGBST to post mortalities online over the course of each calendar year; this reporting has been in place since 2009. Literature cited: U.S. Fish and Wildlife Service. 1993. Grizzly bear recovery plan. Missoula, Montana, USA. U.S. Fish and Wildlife Service. 2017. Final Rule removing the Greater Yellowstone Ecosystem population of grizzly bears from the federal list of endangered and threatened wildlife. 82 FR 30502.
