DEVELOPMENT OF A MACROINVERTEBRATE MULTI-METRIC INDEX TO ASSESS IMPACTS TO WETLANDS IN THE IRRIGATED FLOODPLAINS OF WYOMING
Wetlands remain highly threatened throughout the arid intermountain regions of the U.S. and are subjected to pressures from agricultural, residential, and energy development. In Wyoming, flood irrigation is common in agricultural areas, and paradoxically, water from irrigation is estimated to support or create up to 20% of current wetland acres. Land managers are increasingly aware of the ecological and economic importance of wetlands created or supported by irrigation and there is a growing need to better understand and monitor these highly managed, accidental wetlands. The objective of this study is to develop a multi-metric index that is responsive to different intensities and types of human activities that can be applied to wetlands with both natural and artificial water sources. We collected field data for 56 wetland sites in the Little Snake River basin, including metrics based on landscape, physical, biological, and hydrologic attributes, water quality parameters, plant diversity, and aquatic macroinvertebrates. We identified over 200 wetland macroinvertebrate taxa and selected a set of metrics that are reliable signals of disturbance. The integrated multi-metric index provides information that is relevant to the management of water resources and irrigation-influenced wetland habitats.
