With support from the Muskwa-Kechika Trust Fund as a Seed Grant, Dr. Paul Sanborn carried out a pilot study of soils in relation to prescribed burning in the Northern Rocky Mountains, in collaboration with Perry Grilz, then a Range Officer in the Ministry of Forests. Sanborn and Grilz conducted 3 days of field work in July 2001. Sanborn wanted to test the utility of plant-derived opal (phytoliths) as a soil indicator of vegetation history, in the hope of distinguishing natural grasslands from those created by anthropogenic burning.

This document contains pedon descriptions for sites BC07-03 & BC07-04 for Sanborn's comparative study of grassland soils in the Boreal Cordillera ecozone.

This document contains transcribed August 2007 field notes from 5 observation sites for Sanborn's comparative study of grassland soils in the Boreal Cordillera ecozone.

Forest soil sulphur research was a continuing interest for Dr. Paul Sanborn for more than 30 years, beginning at UBC in the mid-1980s when he took a graduate course in Forest Soils from Dr. Tim Ballard. Among the things that he learned was that soils in much of BC were deficient in sulphur (S). Simultaneously, he became aware of the large amount of research on prescribed fire in BC forests, with broadcast burning being the main method of site preparation across much of the province at that time.

Sanborn undertook various projects in this area of research:

1. UBC Postdoctoral Project on effects of prescribed fire on sulphur in forest soils (1988-90)
2. Cluculz retrospective study (E.P. 886.10) with the BC Ministry of Forests and UNBC
3. Sulphur stable isotope tracer study (E.P. 886.15) with the BC Ministry of Forests and UNBC

Data sets for the Sulphur stable isotope tracer study (E.P. 886.15) include:

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.

Data sets associated with the Arocena & Sanborn 1999 regional soil mineralogy study:

• S234FINL.XLS [data report for mineral horizons from MoF Analytical Chemistry Laboratory, June 20 1996]
• S235FINL.XLS [data report for organic horizons from MoF Analytical Chemistry Laboratory, June 20 1996]
• SAMPLIST.XLS [conversion table for sample numbers used in MoF lab data reports]
• Fe Al extractions.xlsx [assembled from lab data report by L. Arocena for oxalate & dithionite extractions; pyrophosphate extraction data from MoF lab]
• MINSTUDY.XLS [consolidated lab data for organic & mineral horizons, except for BaCl2 exchangeable cations]
• MINCEC.XLS [BaCl2 exchangeable cations & Morgan’s extraction for organic & mineral horizons]
