Description

Abstract: The purpose of this investigation was to determine the status and distribution of sand roller Percopsis transmontana populations in the Willamette River basin. Sand rollers are rare and endemic to the lower Columbia River drainage, including the Willamette River and its tributaries. Historical records are scarce. In 1945, R.E. Dimick and F. Merryfield found sand rollers to be localized in the Willamette River from Albany to Springfield, Santiam River, Rickreall Creek, Mary’s River, and the Coast Fork Willamette River. The Oregon State University museum collection has samples from the following Willamette River drainages: Coast and Middle Forks of the Willamette River, Mary’s River, Luckiamute River, Molalla River, Mill Creek, Long Tom River, and Santiam River. Their preferred habitat is quiet backwaters and pool margins of small to large rivers, usually near vegetation and woody debris over sand. The Oregon Department of Fish and Wildlife surveyed historic and recently documented locations in 2005 to determine the current status and distribution of sandrollers in the Willamette River basin. Sand rollers were collected from at least one location in most of the major Willamette River subbasins sampled.
