A slide along the lower mainstem Big River shows in the upper left corner of the photo just downstream of Blind Gulch. Recent clear-cut unit in foreground of photo appears to have been yarded with tractors on the left, and cable yarded on the right. Trees along draws in the cut areas reflect Class III stream protections. Photo by Rixanne Wehren. 1994.

Photo of unknown area within Big River watershed showing large trees in the riparian zone of the stream, which extends from the center toward the bottom, right. Recent clear cuts with cable yarding are visible up and to the right of center in the photograph. Most of the watershed in view appears to be in very early seral conditions. Photo by Rixanne Wehren. 1994

Aerial close up of areas recently clear-cut after application of herbicides. The herbicides target Ceanothus, a brush species that tends to colonize light gaps but is also a nitrogen fixer. Photo by Rixanne Wehren. 1994.

Close up of lower Big River showing recent logging. The logging on these slopes appears to have been conducted using the cable yarding method. The slopes are beginning to re-vegetate. Note the trees left along the river for the Watercourse and Lake Protection Zone. Photo by David Russell. 1995.

This aerial photo was taken approximately three to four miles up Big River and shows a recently logged slope back away from the stream. Although a small landslide appears to have resulted from a logging road failure, delivery of sediment reached the flood plain but not the stream. The deciduous riparian buffer near the pasture appears to provide filter capacity and would be sufficient to prevent bank erosion by livestock. Photo by Rixanne Wehren. June 1999.
