Forest soil sulphur research
2023.2.2.1 · Subseries · 1988-2011
Part of Dr. Paul Sanborn fonds

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

For July 1-7, 2009, Dr. Paul Sanborn did the first soils field research at the Fort Selkirk volcanic field in central Yukon, with helicopter support and funding from the Yukon Geological Survey.

Initial findings were published in the 2009 edition of Yukon Exploration and Geology, but this paper did not include most of the laboratory data:

Blackburn (eds.), Yukon Geological Survey, Whitehorse, Yukon. pp. 293-304. https://emrlibrary.gov.yk.ca/ygs/yeg/2009/2009_p293-304.pdf [Note that in Fig. 1, the labels for Camp 1 and Camp 2 on map are transposed; Camp 1 should be to the east of Camp 2.]
