This report describes results from a 2011 pilot crayfish inventory of Shenandoah National Park. The objective of the inventory was to document crayfish species that inhabit park waters within each of the three large watersheds that drain Shenandoah N.P.: the James, Rappahannock, and Shenandoah subasins. At least three streams within each subbasin were surveyed for crayfish during the summer season. Surveys included visual searching of all stream habitats in the lower reaches of individual streams for 3-person hours and all crayfish that were observed (n=287) were collected and identified. Five species were documented in the park including Cambarus bartonii bartonii (within the James, Rappahannock, and Shenandoah subbasins), Cambarus longulus (within the James subbasin), Cambarus sp. C. (within the Rapphannock subbasin), Orconectes obscurus (within the Shenandoah subbasin), and Orconectes sanbornii (within the Shenandoah subbasin). With the exception of O. sanbornii, these species are thought to be native and are considered to be relatively common within their respective ranges. O. sanbornii is native to Ohio, Kentucky, and West Virginia.
