Abstract

Vegetation of Pool 3, Cheyenne Bottoms Waterfowl Management Area, was studied from March 15 to September 15, 1969. The objectives of the study were (1) to describe the vegetation in delineated plant communities, (2) to compile a species list for the study area and (3) to determine the phenology of the most prevalent species. Five distinct plant communities were delineated; Distichlis-Eleocharis, Leptochloa, Leptochloa-Scirpus, Scirpus and Typha. One hundred twenty nine species, including 35 species not recorded before in the area, were listed. The therophytic life form was dominant, comprising 54.3% of the observed species. Phenology data were collected for 65 species. High soil moisture content was apparently one factor responsible for the earlier development of Rumex crispus, R. altissimus, Eleocharis palustris and Sciryus paludosus on some sites. Atriplex argentea had the longest life cycle of any observed species, nineteen weeks from initial vegetation to seed dispersal.
