2023.2.2 · Series · 1960-2024
Part of Dr. Paul Sanborn fonds

Series consists of records created and collected in relation to research projects Dr. Paul Sanborn was engaged in, often with other colleagues, during his employment with the BC Ministry of Forests and/or the University of Northern British Columbia. These archival research records are predominantly unpublished documents, reports, data, and photographs. Some of Sanborn's research projects did not result in a formal scientific publication. In other instances, some of Sanborn's research projects resulted in only a portion of the collected data utilized for a formal publication.

Sanborn compiled details about each research project and its associated records in a summary note. Each of these notes is provided in PDF format along with its research project series. These notes serve as an essential guide for researchers who wish to interpret, utilize, and repurpose Sanborn's data for other future research projects.
Forest soil sulphur research
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

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.
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:

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:

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.
Experimental Project (EP) 660

EP 660 was a conventional silvicultural trial established in 1967 which involved single species plantings of lodgepole pine (Pl), white spruce (Sw), and Douglas-fir (Fd) at different spacings. Three installations were established in the Prince George - Vanderhoof area: Buckhorn Ridge, Bobtail Road, and Chilco Creek.

The Archie Creek site is the informal name used for a research installation established in 1971 east of Prince George by the Canadian Forest Service, and subsequently abandoned by the end of that decade. Dr. Paul Sanborn revisited the site in 1995, and sampled forest floors and mineral soils across a range of conifer-broadleaf mixtures established by natural establishment of broadleaf trees among planted lodgepole pines.

Details of the site conditions, sampling methods, and results were published in:

A comparative study of grassland soils at 3 sites in northwestern BC and southern Yukon was published as:

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.)
