Map depicts range reference area exclosure locations for livestock and wildlife in the Fort St. John Forest District.

The Archie Creek site is the informal name used for a research installation established in 1971 east of Prince George by the Canadian Forest Service, and subsequently abandoned by the end of that decade. Dr. Paul Sanborn revisited the site in 1995, and sampled forest floors and mineral soils across a range of conifer-broadleaf mixtures established by natural establishment of broadleaf trees among planted lodgepole pines.

Details of the site conditions, sampling methods, and results were published in:
Sanborn, P. 2001. Influence of broadleaf trees on soil chemical properties: A retrospective study in the Sub-Boreal Spruce Zone, British Columbia, Canada. Plant and Soil 236: 75–82. https://doi.org/10.1023/A:1011973402414

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File of documents consists mostly of unpublished internal and consultant reports, workshop summaries & handouts, and government publications (BC, Canada, USA). Methods-related documents may have been drafts which were superseded later by published manuals.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.
