Patch occupancy of stream fauna across a land cover gradient in the southern Appalachians, USA

Field sampling of four functionally important focal stream consumers within the Little Tennessee River Basin took place in thirty-seven stream reaches between May - July 2009. Sampled reaches all drained an area less than 17 km2, and land cover varied among these reaches. This data was used to model patch occupancy to examine factors that best predicted the prevalence of the four groups.
