Endangered Grizzly Bear: Global and Native to the U.S.

Grizzly Bears: Background

  • Grizzly bears are both native to Texas and are global.
  • They can come from Canada, many parts of the U.S., Mexico, small parts of Asia, and Northwest Territories south through most of British Columbia.
  • Grizzly bears originated in Asia about 1.3 million years ago, being evolved from the Etruscan bears that were in Europe.
  • So the Etruscan bear is the direct ancestor of the brown bear.
  • The grizzly bear's range was reduced and destroyed by hunting, and trapping.

Grizzly Bears: threats and solutions

  • Grizzly bears are considered to be endangered in Canada.
  • In 1975, when the Grizzly Bear came under the protection of the U.S. Endangered Species Act, only about 1,000 were left in the lower part of the U.S.
  • 95% of them who live past the age of 2 die at the hands of humans from gunshots.
  • Their main threats are humans and other bears. Humans are a great threat because of the great population increase.
  • They are hunted as game and were illegally hunted by both landowners seeing them as a threat to their live stock and poachers wanting them for their hides.
  • Some other threats include habitat loss and the salmon collapse.
  • To protect this animal one could adopt a grizzly, and speak up for the wildlife.
  • The solutions would be to decrease the human-cause mortality and protect their habitats.
  • Even enforcing the Grizzly Bear Recovery Plan could help to increase the population.
