Thankfully, the American bullfrog is not considered threatened, and is in fact one of the most populated frog species in the western hemisphere. The American bullfrog is so well populated that despite being caught commercially as a food source in the southern United States, their overall population continues to climb.
Originally native to the eastern US west to the Rocky Mountains and parts of Canada, American bullfrogs are now one of the most invasive amphibians in the world. They can be found in all the western US states, Hawaii, the Caribbean, Europe, Asia, and South America. Attempts have been made at eradication, but no controls have proven effective.
