On this episode of the Kentucky Afield Podcast we are joined by Dr. Monte McGregor, one of the states most accomplished biologist! Monte is an expert in all things related to mollusk, aquatic ecosystems, and water quality. In fact he's helped save nearly 20 animal species that were sure to go extinct, and he's sharing some of that knowledge with us... Find out why those little shells on the bottom of the creeks, lakes and rivers are so important to a healthy environment!
