A Hydrogeomorphological Assessment of Potential Sites for the Reintroduction of Platanthera leucophaea

The eastern prairie fringed orchid, Platanthera leucophaea, was once common across the Midwest but is now listed as a state endangered species. In 1999 the U.S. Fish and Wildlife Service (USFW) issued a Recovery Plan for P. leucophaea that included increasing the size of existing populations and managing the orchid’s habitat to enable its recovery. As the result of a partnership between U.S. Fish and Wildlife, the Michigan Nature Association, and Great Lakes Orchids, LLC., 200 of these orchids will be planted in the Shiawassee National Wildlife Refuge and the Saginaw Wetlands Sanctuary during the spring of 2016. The purpose of this study was to compare the hydrogeomorphology of proposed re-introduction sites with sites known to support populations of P. leucophaea currently. Elevation, hydrology, impervious surfaces, and bedrock geology were evaluated in an attempt to discover the optimal hydrologic conditions for growth, as well as to identify regions of the selected sites that satisfy these requirements.
