RHINELANDER - Half of Wisconsin's mussels and clams fall under endangered or threatened species. A group of volunteers went out Tuesday morning to survey mussels in local waterbeds.
The program was sponsored by the Oneida County Aquatic Invasive Species Program. There's very little information on the state's mussel population, and volunteers say they are very important to local ecosystems.
"Native fresh water mussels are actually very vital to stream ecosystems," said UW-Green Bay graduate student Jesse Weinzinger. "They filter water. They are good indicators to water pollution because they are very sensitive to change."
