The study evaluates the EMAP classification system and sampling design using NEI digital wetland data for portions of Illinois, Washington, North Dakota and South Dakota. A comparison of the EMAP classification to the NWI classification and evaluation of the EMAP sampling design were conducted relative to numbers of wetlands, total areas, average areas, and common versus rare classes. As expected, the EMAP aggregation of NWI data resulted in fewer wetland polygons, each with larger areas, but did not alter the number of wetlands or the total wetland area in each region. Summary statistics based on comparisons of the sampling estimates to true population parameters demonstrated the effectiveness of the EMAP sampling design with the exception of rare wetland classes. Rare EMAP classes, estuarine emergents, and large wetlands (>50 ha) were usually poorly estimated, but the EMAP design is readily adapted to provide better estimates for these categories.
