    Description

    A series of stereo photographs displays a range of residue loadings for harvested units in the Douglas-fir-western hemlock cover type common to the Willamette National Forest. Postburn residue levels are also represented for the Douglas-fir-western hemlock types. Information with each photo includes measured quadratic means and weights for various size classes, woody fuel depth, and duff depth. The stereo photo series is designed to help forest managers appraise woody residue after both timber harvest and treatment with fire in forest types not previously represented by a photo series.
