The Fox-Wolf watershed Alliance and Wisconsin DNR are looking for volunteers to help search for non-native plants and animals that could potentially threaten area rivers and lakes. Snapshot day is a free one day opportunity to learn about identifying and preventing invasive species in our waterways. Families and individuals who want to help make a difference in the environment are encouraged to attend the event on August 18th from 8:30 a.m. to 1 p.m. at the Shawano County Park Pavillions.
