Ordination And Mapping Of Wetland Communities In Nebraska's Rainwater Basin Region, Michael C. Gilbert
Ordination And Mapping Of Wetland Communities In Nebraska's Rainwater Basin Region, Michael C. Gilbert
US Army Corps of Engineers
Forty-seven Rainwater Basin wetlands of south-central Nebraska were evaluated to provide information on vegetation composition, species assemblages determined from direct and indirect ordination methodology, and community characteristics derived from wetlands mapping. Vegetation/soil relationships were evaluated from both vegetational stand and mapping data. Seasonal and year to year vegetation dynamics were evaluated for one study site, Harvard Marsh.
Ordination of vegetational data was accomplished by use of weighted averaging and detrended correspondence analysis. Weighted average ordination results indicated wetland status for the Fillmore, Scott and Massie soil series. Occurrence of upland vegetation on hydric soils and wetland vegetation on non-hydric soils …
