We have a rattlesnake in Michigan called the eastern massasauga. It’s listed as a threatened species under the Endangered Species Act.

One of the threats it’s facing is a disease called snake fungal disease, and it can kill the snakes. 

Researchers have figured out some clues about how the pathogen affects the snakes.

The eastern massasauga rattlesnake is now listed as a threatened species.

Scott Hicks is a field supervisor in Michigan with the U.S. Fish and Wildlife Service. He says the massasauga’s new status is due to the loss of its wetland habitats.

The Eastern Massasauga — the sole rattlesnake to inhabit the state of Michigan — is facing rapid population loss that's prompting national concern for Michigan wildlife.

In September 2015, the U.S. Fish and Wildlife Service proposed to list the snake as a "threatened species" under the Endangered Species Act, which would qualify the snake for national funds to help preserve the species.

When you think about rattlesnakes, you might picture Arizona. Or Texas. Somewhere out in the desert. But one snake’s rattle doesn’t come from the deserts of the Southwest. It’s from the pine forests of Michigan.

In fact, Michigan is a stronghold for the eastern massasauga rattlesnake.
