Four important timber producing plant communities of the Northwest (Douglas-fir, true fir, ponderosa pine and mixed conifer) were sampled to determine intensity of snag utilization by wildlife for cavity nesting and piciformes feeding. Samples were analyzed, by habitat types, to determine snag occurrence (on a per acre basis) and species of snag preferred. Utilization relative to five snag characteristics (hardness, height, "dbh", bark and limb conditions) was analyzed. Recommendations are given regarding minimum number of snags to be left in logging operations for each community. Samples were considered too small for statistical analysis.
