During a year away from studies in 1987-88, Dr. Paul Sanborn developed a successful grant proposal to the Science Council of BC (SCBC) to pursue a postdoctoral project with Dr. Tim Ballard in relation to sulphur-deficient soils in BC and prescribed fire. This project built on an existing broadcast burning study conducted by Macmillan Bloedel Ltd. near Port Alberni on Vancouver Island, led by Bill Beese (later at Vancouver Island University). Dr. Sanborn's work addressed sulphur forms and amounts in the soils at these sites, and the chemical processes influencing sulphur availability in relation to prescribed fire.
Only one part of this work was eventually published:

The remainder of the work was documented in this Project Completion Report to SCBC, dated February 28, 1990, and entitled "Effects of Prescribed Fire on Sulphur in Forest Soils".
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:
- UBC Postdoctoral Project on effects of prescribed fire on sulphur in forest soils (1988-90)
- Cluculz retrospective study (E.P. 886.10) with the BC Ministry of Forests and UNBC
- Sulphur stable isotope tracer study (E.P. 886.15) with the BC Ministry of Forests and UNBC
This paper by Brad Hawkes describes, from a newspaper media's perspective, changes in how fires were fought, reported, and described from 1912-1961 for significant fire years in the Prince George area.
