The state Nature Preserves Commission has given three WKU professors its annual award for work that protects biological diversity.
Alfred Meier, Ouida Meier and Scott Grubbs were given this year's Biological Diversity Protection Award for their work creating the Upper Green River Biological Preserve. The preserve is on the banks of the Green River in Hart County.
The Green River is the most important river in Kentucky for the conservation of rare native mussels and fish. It hosts 109 fish species and nearly 60 mussel species. The area is also important for an endangered bat species found on the preserve and as a breeding and migratory habitat for songbirds.
Volunteers from across the Commonwealth will gather in Greensburg Saturday to help with the annual "Clean the Green" project. They'll be picking up trash that has accumulated along a twenty mile stretch of the river.
