A half-decade after the Yellowstone grizzly was listed as a threatened species in , the population crashed to fewer than bears; bear numbers have steadily rebounded in the years since, but a vigorous scientific dispute persists over what constitutes a "recovered" population.

Many see human-provided food as unnatural when, in fact, it is a stepping stone to adopt the bear in its natural habitat.

Although grizzly bear numbers in this region have significantly risen from to nearly in the past 40 years, activists fear that removing the grizzly from protection would be a premature decision, and could reduce numbers by The proposed plan to delist the grizzly bear could allow hunting of the bears to begin as soon as January, This book highlights the grizzly's anatomy, life cycle, diet, and range to aid learners in understanding the importance of these land-dwelling killers.

The bear has been listed for 42 years, despite multiple efforts. A Proposed Delineation of Critical Grizzly Bear Habitat in the Yellowstone Region Of color - marked grizzly bears, there were known mortalities ; 79 were killed within Yellowstone Park, while 58 were killed outside the Park.
The Interagency Grizzly Bear Committee was formed in to help ensure recovery of viable grizzly bear populations and their habitat in the lower 48 states through interagency coordination of policy, planning, management, and research.
Many people have been working on this recovery for decades, for some; it has been most of their career. HELENA, Mont. — After 42 years on the endangered species list, the Yellowstone grizzly bear — whose numbers have grown to more than from fewer than — will lose its protected status.
The grizzly bear recovery plan outlined three demographic recovery criteria to be met in order to consider delisting of the Yellowstone grizzly: 1) A minimum of 15 females with cubs-of-the-year be maintained over a running 6-year average both inside the Recovery Zone and within a square mi area immediately surrounding the Recovery Zone 2) Sixteen of 18 bear management units within the.
Another critical element, upon which many agree, is the need for funding. An estimated $ million will be needed each year to fund research, public education, monitoring, and other grizzly. Brown, D. E., The Grizzly Bear in the Southwest. Norman: University of Oklahoma Press.

In a statement earlier this year, Wenk stated that bear hunting could disrupt tourism, because visitors come to Yellowstone, in part, to see the bears in their natural habitat.
