In the mid-1990s, Dr. Paul Sanborn worked with Dr. Lito Arocena of UNBC to assemble and interpret basic physical, chemical, and mineralogical data for typical soils at important long-term forestry research sites in central and northeastern BC. The key results were published as:

J.M. Arocena and P. Sanborn. 1999. Mineralogy and genesis of selected soils and their implications for forest management in central and northeastern British Columbia. Canadian Journal of Soil Science 79: 571-592. https://doi.org/10.4141/S98-07

Nine pedons were involved, with 7 located at the sites of 4 Ministry of Forests Experimental Projects (E.P.), and 2 at the Aleza Lake Research Forest.

The BC Ministry of Forest's EP 1148 Long-term Soil Productivity (LTSP) study addresses two key factors— soil porosity and site organic matter—that potentially limit tree growth and site productivity in the timber-harvesting land base and that can be affected by forestry operations.

This establishment report for EP 1148, "The effects of soil compaction and organic matter retention on long-term soil productivity in British Columbia (Experimental Project 1148)", is accompanied by a floppy disk containing 12 data sets (see 2023.2.2.11.2).
