Great Basin Naturalist


Kalsow Prairie, a mesic prairie remnant in central Iowa, was acquired by the state in 1949 and later established as a botanical reserve. This study concerns a complex of 14 potholes and adjacent drainage areas within the prairie. The potholes varied in depth and degree of fill and are thus useful in studies of plant succession. All 14 potholes exhibit zonation patterns. A total of 36 transects were taken in the various community zones. Canopy cover data were taken in every zone. The zones are ordinated into three-dimensional space as well as clustered. Interspecific association patterns are elucidated. A successional sequence is proposed.
