Some of the world's foremost bear experts have declared that six out of the world's eight species of bears are threatened with extinction - but not the American black bear.
Among the eight species of bears, only the American black bear is secure throughout its range, which encompasses Canada, the United States and Mexico.
Technically a marine mammal, the polar bear is distinct from the other seven terrestrial bears and has a different specialist group. In 2006, the polar bear was listed as Vulnerable on the IUCN Red List of Threatened Species, a global analysis of the conservation status of thousands of species, updated annually, with in depth analysis once every four years.
The only bear presently classed as Endangered is the giant panda. That status remains unchanged despite enormous efforts in China directed towards its conservation, including the establishment of nearly 60 panda reserves, a ban on logging, and widespread reforestation programs, said the bear scientists.
