Figure 1. Ecological Classification System (ECS) in Minnesota: site location for prairie cordgrass, purple prairie clover, and spotted joe-pye weed, and the two dendrogram clusters by site location for each species. The shading identifies the three biomes of the ECS in Minnesota. The sites for each species are shown on each individual map. The circles correspond to populations belonging to one cluster of the dendrogram (Fig. 2, 3, and 4). The squares correspond to populations belonging to the second cluster of the dendrogram (Fig. 2, 3, and 4).
