This is a map of the 1994 USFS Landsat vegetation size data within 90-meter riparian buffer zones in the Walker Creek sub-basin.
Much of the riparian zone of Walker Creek appears to lack mature riparian forest although, because of the one hectare resolution,
individual trees and small groves might not show in this coverage. Riparian character changes in upland areas which are forested,
with trees typically in the Small/Medium size class (12-20" diameter). Data provided by the U.S. Forest Service Spatial Analysis
Lab in Sacramento, CA. Scale = 1:173,102 .
