Endangered and Threatened Plant Species of Schwamberger Preserve, Lucas County, Ohio

Abstract

Of the 425 plant taxa observed within Schwamberger Preserve, 8 taxa (1.88%) are listed on Ohio's legal list of endangered species prepared by the Ohio Department of Natural Resources. Eight taxa (1.88%) are on the legal list of threatened species. The location of the 5 plant communities within the preserve is governed by variation of the depth of the water table rather than variation of soil pH. The future of Schwamberger Preserve, as a viable scientific study area, will be determined by management practices such as acquisition of a buffer zone, control of the aspen thickets, and maintenance of existing excavations and creation of one or two new excavations to serve as specific study sites.
