5 Summary

Twenty-four species of conservation concern, representing 50 occurrences, were located on FLW during this study. No Federally Endangered or Threatened species was found on FLW during this survey. However, 7 Missouri-Rare species, 6 Missouri-Status Undetermined species, 10 Missouri-Watch List species, and 1 Missouri-Extirpated species (observed during migration) were located on FLW.

Of the 24 listed species identified on FLW, 5 species of birds were observed only during fall or spring migration and do not appear to have a reproducing population on FLW. One listed species of freshwater mussel was not found living within the boundaries of FLW; however, live specimens were found several miles downstream. Thus a total of 18 reproducing populations of listed species of plants or animals were discovered.

Surveys for common species of freshwater mussels, fish, amphibians, reptiles, and birds produced species lists for all groups that are consistent with what is expected to occur in the Upper Ozarks. This result indicates that species biodiversity (based upon species presence) on FLW is relatively intact.

Surveys of natural communities indicate that few high quality natural communities exist on FLW. Very few areas remain that were not negatively impacted by past land use. The floral study of Falls Hollow sandstone glades found many weedy, non-native plants, interspersed with conservative glade plant species. Many of the existing natural communities have become overgrown and do not represent high quality natural communities. Management strategies emphasizing landtype associations (i.e., bottomland forests, savanna, upland forests) were developed to enhance the natural communities associated with these landtype associations.
