How Many Grizzly bears are left in the World today?

In the lower 48 states the grizzly bear population (1975) was estimated at between 1,200 and 1,400 bears making it a threatened species.

Today that has recovered and they no longer meet the requirements to be considered threatened but now are "watched". Estimates range from 4,000 to 6,000 but accurate counts are not available. Populations in Alaska are well established and flourishing.
