Abstract

Vegetation of the slope forests along the Des Moines River in the area of the Saylorville Reservoir was surveyed with the objectives of determining composition of these forests and of providing data prior to flooding. The study consisted of two sections - transect study and a random-point study. The transect study provided data for which species-pair correlations were determined. The random-point study provided a more detailed description of the species composition. Average cover values for herbaceous species which are presented indicate great variability from stand to stand. The same conclusions were drawn from the importance values of canopy species. The continuum approach was used to order the data. Many herbaceous species show trends in relation to the continuum index, indicating variations in ecological amplitude of the component species. Parthenocissus quinquefolia decreases in stands with high continuum-index numbers, while Anemonella thalictroides shows the reverse tendency.
