Relative Frequency of Habitats--Based on results of principal-components analysis and qualitative data, I subdivided the drainage system into the following habitats: emergent cattails (thick cattails), prairie sedge meadows (thick cover of grasses, sedges, rushes), forest (thick cover by over-story canopy), cattail-forest transition (cattail-dominated channel with minimal but significant cover by over-story canopy), pioneer mudflat (high erosion potential and bank-side vegetation sparse and dominated by early succession taxa), and turf-grass (bank-side cover of Bermuda grass Cynodon dactylon).
Loadings on component 2 were dominated by distance to nearest tree (-0.83) and bank-side over-story canopy (0.31).
Within the study area plots were used to sample herbaceous plants, woody seedlings, saplings, and over-story trees according to the Vegetation Monitoring System (VMS) of the MDC.
