Vegetation Information for the ISRO Vegetation Inventory Project
1999. Vegetation Information for the ISRO Vegetation Inventory Project
A total of 52 community types were described in the course of the survey. An additional 5 variants were recognized because they contained structural or floristic patterns somewhat different from other stands in the type. A total of 187 plots were collected to describe these types more carefully and to verify their compositional characteristics. The vegetation survey turned up at least one new plant species for the park and the eastern United States, Prosartes (Disporum) trachycarpa (Judziewicz et al. 1997). Ordination of all 187 plots and 400 taxa revealed three large groups, upland forests and woodlands, upland open bedrock vegetation, and wetlands. The wetlands were separable into two subgroups, the open shrub/herb dominated group and the more forested swamps. Within the upland open bedrock group, individual types could be distinguished fairly well within the overall dataset. These types show a pattern from very open bedrock types, such as the Great Lakes basalt (conglomerate) bedrock lakeshore (#51) or the Great Lakes basalt/diabase cliff (#52), that share little in common with more forested types, to those that overlap in composition with these forests, such as the Boreal rocky shrubland (#29), the Spruce-fir basalt bedrock glade (#62), and particularly the Canada yew mixed shrubland (#35). Somewhat surprisingly, the more open herbaceous wetland group, such as the Northern Water Lily aquatic wetland (#50) appear clustered near types in the open bedrock group, such as the bedrock lakeshore (#51). This may reflect the somewhat lower diversity found in both types, as well as the compression of the diversity of types into 2 axes. The third axis clearly separates the two groups.
