Research on the ecological functions of coarse woody debris (CWD) in forests, and techniques for inventorying CWD, were major topics for forest ecologists and soil scientists during Paul Sanborn's years with BC Forest Service research program (1991-2002).

File of documents consists mostly of unpublished internal and consultant reports, workshop summaries & handouts, and government publications (BC, Canada, USA). Methods-related documents may have been drafts which were superseded later by published manuals. In some cases, the document has a memo or email attached which provides some additional context.
