AB: Two United States Environmental Protection Agency (U.S. EPA) macroinvertebrate sampling protocols were compared in the Mid-Atlantic Highlands region. The Environmental Monitoring and Assessment Program (EMAP) wadeable streams protocol results in a single composite sample from 9 transects whereas the Rapid Bioassessment Protocol (RBP) II consists of a single composite sample from 4 locations within a riffle. Separate macroinvertebrate samples were collected by U.S. EPA and United States Forest Service (USFS) using both sampling protocols from 12 streams in 2002. Samples were sub-sampled to 300 organisms and identified to lowest taxonomic level possible. Non-metric multidimensional scaling (NMS) was used to determine major patterns in macroinvertebrate assemblages, and Bray-Curtis similarity analysis was used to explore differences in species composition between methods. No distinct differences were found between samples collected using the two sampling methods. Comparisons of taxa richness, functional feeding group, and habit between sampling methods all showed 80% or higher similarity. Although this work was reviewed by EPA and approved for publication, it may not necessarily reflect official Agency policy.
