In 1989, WPC is given the 380-acre farm of Elizabeth M. Totten of Plaingrove, Lawrence County for Plaingrove Fen Natural Area, featuring the spreading globe flower.

This project features a number of alkaline wetland seeps along Taylor Run that are of statewide significance. These contain several unusual plant species, including one of the only known western Pennsylvania populations of spreading globe-flower, a State Endangered wetland buttercup. The upland forests harbor an active great blue heron rookery.
