Abstract

From 1999 to 2004, Weyerhaeuser1 conducted surveys to monitor retained habitat structure in 193 VR blocks, 98 benchmark unharvested sites (including pre-harvest experimental sites), 19 blocks with old remnant patches, 19 blocks with riparian reserves, 8 older clearcuts and 6 'scrub' sites. Measured habitat attributes included live trees (species, DBH, height), snags (species, DBH, height, decay class), coarse woody debris (CWD; species, diameter, decay class, height above ground), cover layers (canopy, small tree, shrub, herb, moss, litter, mineral soil), dominant shrub and herb species, and site series. Summaries are provided for major types of these attributes and for some important specific structures (e.g., large cedar snags, large well-decayed CWD, etc.). The monitoring design allows several types of comparisons identified as priorities in Weyerhaeuser’s Adaptive Management Framework.
