Description

Abstract: Pit Sculpin Cottus pitensis are endemic to Goose Lake basin, south-central Oregon. The species was listed as sensitive by the U.S. Forest Service Region 6 and Bureau of Land Management and by the State of Oregon. Recent surveys suggested Pit Sculpin have a restricted range in Oregon. The objectives of our surveys were to: 1) describe the current distribution and estimate the abundance of Pit Sculpin in Drews and Camp creeks, 2) describe the fish assemblages in Drews and Camp creeks, and 3) describe stream habitat conditions and collect habitat covariate data at each sampling location for modelling capture probabilities and abundance. We found Pit Sculpin distribution was limited to approximately 5.2 km of Drews Creek and 0.8 km of Camp Creek. Pit Sculpin primarily occupied riffles with gravel substrate. We estimated 12,331 and 1,518 Pit Sculpin in Drews and Camp creeks, respectively.
