Additions to the Flora of Mounds State Park and Preserve, Madison County, Indiana

Rothrock et al. (1993) documented 455 species of vascular plants at Mounds State Park and Preserve, Madison County, Indiana. During the 2009 growing season, an additional floristic survey was conducted, including a 16.6 hectare annex to the south end of the park. An additional 129 species of vascular plants, representing 98 genera in 46 families,were vouchered. Of these species, 94 (,73%) were native, 35 (,27%) were adventives, and 87represent Madison County records. Combining the results of the two studies yielded 584 total species, 478 (,82%) native species, and 106 (,18%) adventive species. For native species, the Floristic Quality Index (FQI) 5 96.2 and the mean Coefficient of Conservatism(C) 5 4.4, whereas for all species, the FQI 5 87.1 and the mean C 5 3.6. The floristic quality data indicate that the conservation and richness of Mounds State Park and Preserve are of paramount importance from a regional perspective.
