Grizzly bears are hard to count, but the latest estimate from the federal Interagency Grizzly Bear Study Team , puts that population at 714 bears. Throughout the entire ecosystem, Gunther said, “I think we could easily be up around a thousand.” Based on such numbers, on the trend over recent decades, and on their belief that the Greater Yellowstone Ecosystem is now about as full of grizzly bears as it can be, many of the state and federal bear biologists suggest that it’s time to remove the Yellowstone grizzly from the list of “threatened” species.
THIS IS CONTROVERSIAL. Everything about the grizzly is controversial. Some conservationists outside the agency circle have challenged the population estimates, the positive prognosis, and the advisability of delisting. They’re concerned about the likely effects of renewed sport hunting and the long-term food security of the Yellowstone grizzly.
