Iowa Forest Communities, Iowa Flora
The vegetation of this relatively undisturbed forest in central Iowa was sampled by a transect across a stream valley to determine species presence. The presence data were used in delineation of communities and in a computer ordination of the vegetation. Analysis revealed four distinct groupings, or communities, in the preserve: oak-hickory, prairie opening, floodplain and north-facing slope. The communities and their boundaries, determined through comparisons of species distribution diagrams, were also identified in the continuum of plots arrived at by an ordination technique. The communities showed a strong relationship to the topography of the preserve. Species composition of the communities and successional trends in the preserve are discussed. A complete list of the vascular plants found in the preserve, along with their abundance and place of occurrence, is presented.
