Abstract : As part of a national study, vegetation associated with known hydric and nonhydric soil series was sampled in selected wetlands in the Rainwater Basin and Sandhills regions of Nebraska. Weighted averages, presence/absence averages, and Michener averages were calculated for vegetation in each soil series and individual wetlands within soil series, based on importance values and ecological indices assigned by the National Wetland Plant List. Eleven times out of twelve, hydric soils were designated as wetlands based%on vegetation. One hydric soil in the Sandhills region supported a higher proportion of species adapted to non-wetland conditions. Four out of five samples of nonhydric soils supported a preponderance of upland species. Results obtained with weighted and presence absence averages may be preferred over weighted averages because information concerning species dominance (e.g., percent cover) is not required. However, correct identification of all species is more critical with use of presence/absence averages.
