This USGS ortho photo is displayed with USFS 1996 Landsat derived tree size and vegetation type data (one hectare scale) for the riparian zone and roads at a mid-elevation location. Note that main haul roads under-represent disturbance which could cause increased sediment yield or peak flow. The Non-Forest signature (pink) in the riparian appears to be increased in riparian zones by road location near the stream. Roads data from SPI.

This is a zoom in on a USGS ortho photo on upper South Fork Battle Creek near Cold Creek showing road-stream crossings in yellow. Major haul roads create disturbance, but landings and skid trails may add to cumulative watershed effects potential. See Info Links for more information.
