Sculpin (Cottus) distribution in the Kootenai National Forest and northwestern portions of the Flathead National Forest, Montana / submitted by Scott A. Edson for the Kootenai National Forest.

Abstract

am appreciative for the logistical support, planning and editing of this report by Doug Perkinson and Dave Center. Also, the Montana Natural Heritage Program staff were supportive and provided follow-through in a timely manner.Don Skaar and his staff at the Fish, Wildlife and Parks, Libby field office, and Wayne Kasworm and his staff (same base) were especially supportive with equipment and lodging.Lewis Young of the Eureka Ranger District readily provided information and suggestions pertinent to achieving the study objectives. Also, my thanks to the rangers and staff at the Fortine Ranger District for providing occasional lodging and facilities during the study.Qualitative evaluations of stream habitat were used to assess differences between sites.Individual species habitat requirements were similar enough to require that quantitative measures of a number of physical, chemical, and biological conditions be made before distinctions could be determined for individual species.Electroshocking in conjunction with D-netting was the best method for sampling sculpin. Alternate sampling methods may be valuable for obtaining additional information.
