Efficacy of four different sampling methods of wetland macroinvertebrates

Various samplers originally designed for sampling macroinvertebrates in aquatic ecosystems have been modified for use in wetlands with moderate success. Smaller, quantitative samplers often do not capture rare and mobile organisms whereas larger, qualitative samplers do not allow for density estimates. Sorting time is another important variable in deciding sampling regimes. This study examines the efficacy of four invertebrate samplers in three different wetlands.Sponsored by: Georgia Environmental Protection Division U.S. Geological Survey, Georgia Water Science Center U.S. Department of Agriculture, Natural Resources Conservation Service Georgia Institute of Technology, Georgia Water Resources Institute The University of Georgia, Water Resources Facult
