Detrended correspondence analysis of herbarium records clarified patterns in the composition of grassland-endemic plant species at 173 of the historical sites, in relation to physiography, bedrock type and other elements of geographical variation.� An expanded community classification scheme is proposed for native, upland grasslands and meadows in the state.
Results of this study are useful (1) as input for a gap analysis establishing natural area protection priorities; (2) to define models of species composition for management and restoration of remnant grasslands; (3) to create templates for the creation of new native grasslands that will favor success in establishment and enhancement of wildlife habitat under particular sets of soil and microclimatic conditions; and (4) to identify the best sources for local genotypes of species used in restoration and grassland creation.
