While at the Ministry of Forests, Dr. Paul Sanborn carried out two retrospective studies which examined soil chemical properties at long-term silvicultural research sites where different vegetation types had been created, either as planned or unplanned experiments. These studies were Experimental Project (EP) 660 and a research project at the Archie Creek site.

File contains 2 rolls (51 slides) taken September 25-26, 1995 that depict paired views of plot vegetation and forest floor surface. Handwritten number notations on slide frames indicate plot numbers from the original research installation.

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.

A comparative study of grassland soils at 3 sites in northwestern BC and southern Yukon was published as:
Sanborn, P. 2010. Topographically controlled grassland soils in the Boreal Cordillera ecozone, northwestern Canada. Canadian Journal of Soil Science 90: 89-101. https://doi.org/10.4141/CJSS09048

This grew out of a field trip with Ministry of Forests range personnel to the Stikine and Tuya River valleys, near Telegraph Creek BC on August 27-28, 2007. (Two pedons were sampled in 2007, BC07-03 and BC07-04, but those results were not included in the paper.)

In August 2008, Dr. Paul Sanborn returned to the Stikine to sample pedon BC08-06, after field work in Yukon which collected the other two pedons used in the paper, from near Carmacks (Y08-39) and Kluane Lake (Y08-41). (An additional pedon from Kluane, Y08-43, was sampled and analyzed, but it was from a forested site and was not included in the paper.)
