Part of Dr. Paul Sanborn fonds

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".

"Mineralogy of clay and sand fractions of soils developed from till, glaciofluvial and glaciolacustrine deposits in central interior British Columbia" was a preliminary internal report that provides some background to Arocena and Sanborn's regional soil mineralogy study, as well as a compilation of the mineralogical data.

The key results from this work were later published as:

Sulphur stable isotope tracer study (E.P. 886.15)
2023.2.2.1.3 · Sub-subseries · 1998-2011
Part of Dr. Paul Sanborn fonds

The Sulphur stable isotope tracer study (E.P. 886.15) field experiment was installed in young lodgepole pine stands at two sites in the Prince George Forest Region in 2001, with fertilizer treatments applied in late 2002. These sites are designated as Kenneth Creek (east of Prince George) and Holy Cross (south of Fraser Lake). (The Kenneth Creek installation was established near plots of the older E.P. 886.13 in the same stand.) Full experimental details, including pretreatment soil and foliar date, were given in:

Sanborn, P., R.P. Brockley, B. Mayer, M. Yun, J. Prietzel. 2005. Sulphur fertilization of lodgepole pine: a stable isotope tracer study (E.P. 886.15): Establishment report. Tech. Rep. 020. B.C. Min. For., Res. Br., Victoria, BC. http://www.for.gov.bc.ca/hfd/pubs/Docs/Tr/Tr020.htm

The Kenneth Creek site was attacked by mountain pine beetle in 2006, resulting in at least 80% tree mortality. In 2013, the stand was levelled in order to enable replanting, and due to poor communications within the Ministry of Forests, the opportunity to salvage this installation was lost. The Holy Cross site was hit by a wildfire in 2010, and most of the research plots were destroyed.

Preliminary results from foliar analysis, sufficient to demonstrate that our stable isotope tracer approach could detect fertilizer uptake, were published in:

Cluculz retrospective study (E.P. 886.10)
2023.2.2.1.2 · Sub-subseries · 2001-2005
Part of Dr. Paul Sanborn fonds

During Dr. Sanborn's years with the Ministry of Forests research program (1991-2002), he worked on forest fertilization research with silviculturist Rob Brockley (retired; formerly at Kalamalka Research Station, Vernon, BC). Brockley’s work in the 1980s and early 1990s had documented the widespread pattern of sulphur deficiencies across the BC interior, and the superior response of managed stands to fertilization treatments involving sulphur (S) and nitrogen (N) rather than nitrogen alone.

To progress farther, different methods for understanding the fate of sulphur fertilizers in forests and soils were needed. Sanborn contacted the stable isotope group at the University of Calgary which had done important work on the fate of pollutant sulphur emitted by oil and gas extraction and processing in Alberta, using natural abundances of sulphur stable isotopes as a tracer. This was the beginning of a collaboration with Dr. Bernhard Mayer of the University of Calgary, and also with his German soil scientist colleague, Dr. Joerg Prietzel (Munich Technical University).

The research team engaged in the Cluculz retrospective study (E.P. 886.10) for the BC Ministry of Forests.

An ancillary project involved resampling (2002 - foliage, 2003 - soil) of a previously fertilized (1990) installation (E.P. 886.10) south of Cluculz Lake in order to compare the longer-term effects of different fertilizer sulphur forms on soil and foliage chemical properties. Results were published as a journal article and a Ministry of Forests Extension Note:

UBC Postdoctoral Project "Effects of Prescribed Fire on Sulphur in Forest Soils"
2023.2.2.1.1 · Sub-subseries · 1988-1991
Part of Dr. Paul Sanborn fonds

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 the Project Completion Report to SCBC, dated February 28, 1990.

Thirty-four of the accompanying project data files were selected for archival retention.

Thirty-four data files were selected for archival retention. There is some redundancy of content among these, with some formatted for incorporation as tables in the report appendices, and others containing some of the same data, but set up as input files for a statistics program. These account for almost all of the data listed in the Project Completion Report appendices. No glossary of variable names is provided, but these should be identifiable by referring to the Report.
