Abstract

Few researchers have examined the communities and ecology of disturbed grasslands, but many have studied native remnants. Disturbed grasslands abound, however, and warrant greater attention. The vegetation of a former pasture in northern Illinois was examined to decide whether the discrete or continuum community model was more applicable. Quantitative plant data, gathered according to the line-intercept method, were analyzed employing the multivariate classification TWINSPAN and the ordination Detrended Correspondance Analysis. Floristic records and soil data enhanced the community analysis. Both the ordination and classification revealed five discrete community types. Poa pratensis/Phleum pratense, Aqropyron repens, Phalaris arundinacea, Carex stricta, and Sagittaria latifolia dominate the five community types, respectively. The important environmental factors influencing these communities were moisture and flood regimes. Ideas for future management and research are suggested.
