The Missouri Resource Assessment Partnership (MoRAP) will gather and quantify both natural and anthropogenic data relative to the distribution of the Coldwater Crayfish (Orconectes eupunctus) within the Spring River, Eleven Point, Strawberry River and lower Black River drainages.  This study area crosses the Missouri/Arkansas state border.  Generally, landscape scale natural variables will include factors related to soils, geology, landcover, and hydrologic qualities, while anthropogenic variables will include factors related to agriculture, urbanization, mining, hydrology, and water quality.  These variables will be quantified for the contributing area to each stream segment.  A student working with the Arkansas Cooperative Fish and Wildlife Research Unit will use this data to invistigate factors affecting the distribution and decline of the Coldwater Crayfish.
