Mixed-conifer forests of central Oregon: Effects of logging and fire exclusion vary with environment

Publications Posted on: October 07, 2015
Twentieth-century land management has altered the structure and composition of mixed-conifer forests and decreased their resilience to fire, drought, and insects in many parts of the Interior West. These forests occur across a wide range of environmental settings and historical disturbance regimes, so their response to land management is likely to vary across landscapes and among ecoregions.

Stereo photo series for quantifying forest residues in the Douglas-Fir-Hemlock type of the Willamette National Forest.
