The BC Ministry of Forest's EP 1148 Long-term Soil Productivity (LTSP) study addresses two key factors— soil porosity and site organic matter—that potentially limit tree growth and site productivity in the timber-harvesting land base and that can be affected by forestry operations.

This establishment report for EP 1148, "The effects of soil compaction and organic matter retention on long-term soil productivity in British Columbia (Experimental Project 1148)", is accompanied by a floppy disk containing 12 data sets (see 2023.2.2.11.2).

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.

Sulphur stable isotope tracer study (E.P. 886.15)
2023.2.2.1.3 · Sub-subseries · 1998-2011
Parte de 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:

Parte de Dr. Paul Sanborn fonds

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.
Cluculz retrospective study (E.P. 886.10)
2023.2.2.1.2 · Sub-subseries · 2001-2005
Parte de 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:

The Kluane Lake area of SW Yukon was a continuing focus of Dr. Paul Sanborn's research for more than a decade, and generated several productive collaborations. Key themes included biological soil crusts in boreal grasslands, and interactions between aeolian sediment deposition, slope processes, and fire in boreal grassland and forest soils.

Research results appeared in these publications:

The 2003 field work with Darwyn Coxson was a pilot study to assess the types and distribution of biological soil crusts in boreal grasslands in the Kluane Lake area. Eight sites were visited at which the team sampled the crust and the uppermost A horizon immediately underneath it. Note that site numbers Y03-03, -04, -05, -06, -07, -09, -10 and -12 were indicated as sites 3, 4, 5, 6, 7, 9, 10 and 12 in Table 1 of Marsh et al. (2006). Additional crust sampling was conducted at two additional sites (“Peninsula”, “Silver City”) in 2004; details of sampling methods and site locations are in Marsh et al. (2006).

Results from 2009 field work were presented in Sanborn and Jull (2010), along with soil charcoal radiocarbon dates from 2003-2008 sampling which were used to reconstruct fire history in the Kluane Lake area. The 2003 (a single site at Silver City), 2004, and 2008 field work consisted of a reconnaissance of grassland and forest sites across a range of aspects and slope positions in order to recover buried soil charcoal.
