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:

The Lost Chicken Mine, a placer gold mine in eastern Alaska, approximately 120 km west of Dawson City, Yukon, is an important fossil locality for the late Pliocene (approximately 2.5 – 3.0 million years ago). A comprehensive account of the stratigraphy and paleontology of this site was given by:
Matthews, J.V., Jr., J.A. Westgate, L. Ovenden, L.D. Carter, and T. Fouch. 2003. Stratigraphy, fossils, and age of sediments at the upper pit of the Lost Chicken gold mine: new information on the late Pliocene environment of east central Alaska. Quaternary Research 60: 9-18. https://doi.org/10.1016/S0033-5894(03)00087-5

Dr. Paul Sanborn visited the site on July 20, 2004, as part of a group led by Duane Froese (Professor, University of Alberta). The group concentrated on a single exposure (~ 2 m thick) straddling the Lost Chicken tephra, a volcanic ash bed (2.9 ± 0.4 myr) which is a major stratigraphic marker at the site. Sanborn described, photographed, and sampled this exposure, and obtained a basic set of characterization data. Intact samples were collected but thin sections were never produced.

Northern Rockies pedological study

For this Northern Rockies pedological study, Dr. Paul Sanborn conducted field work jointly with researchers from the Ministry of Forests and Agriculture Canada from August 21-24, 2012, at two clusters of sites along the Alaska Highway west of Fort Nelson: near the Tetsa River crossing at km 585, and ~4.5 km west of Toad River at the "Poplars" campsite.

The focus of the study was on soils currently or recently containing permafrost as well as associated soils on nearby sites with warmer microclimates, with a total of 6 pedons described and sampled. One of these, an Organic Cryosol (pedon BC12-08), was documented in a short paper:

Sanborn, P., C. Bulmer, M. Geertsema, and S. Smith. 2022. A proposed Folic subgroup for the Organic Cryosols. Canadian Journal of Soil Science 102: 811–816. https://doi.org/10.1139/cjss-2021-0182

Associated soil microclimate monitoring occurred at this site, and is documented in:
Hasler A., Geertsema M., Foord V., Gruber S., Noetzli J. 2015. The influence of surface characteristics, topography and continentality on mountain permafrost in British Columbia. The Cryosphere 9: 1025–1038. https://doi.org/10.5194/tc-9-1025-2015

Some of the data from both papers was presented as a poster at the Canadian Society of Soil Science annual conference in 2013.

The highlights of the 2022 paper were presented at an online meeting of the Soil Classification Working Group of CSSS on January 20, 2023.

The sequence of site numbers is BC12-08, -09, (-10 was not used), -11, -12, -13, -14, and -15. Note that BC12-13 was described and sampled, but not photographed. An additional pedon designated as BC12-13A was located within ~10 m of BC12-13 on the same terrace, and had what appeared to be a buried fire-reddened layer under a possible buried Ah horizon. This pedon was photographed but not described or sampled.

Soils research at Kluane Lake, Yukon
2023.2.2.8 · Sous-série organique · 2003-2014
Fait partie de Dr. Paul Sanborn fonds

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.

Forest soil sulphur research
2023.2.2.1 · Sous-série organique · 1988-2011
Fait partie de 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

With the assistance of the Yukon Geological Survey, Dr. Paul Sanborn was able to visit the terminus of the Klutlan Glacier, a major outlet glacier which originates in the Alaska portion of the St. Elias Mountains. The stagnant terminus has a thick cover of debris, including a large component of White River tephra, providing enough soil material to support a boreal forest. Field work occurred on July 8, 2007, and results were published as:

Ministry of Forests E.P. 886.13 was established by silviculture researcher Robert Brockley between 1992 and 1999, and consisted of 8 installations across the interior which shared the same experimental design. Five involved lodgepole pine and three involved interior spruce. Complete descriptions of the site characteristics, experimental treatments, and early results are given by:
Brockley, R.P. and D.G. Simpson. 2004. Effects of intensive fertilization on the foliar nutrition and growth of young lodgepole pine and spruce forests in the interior of British Columbia (E.P. 886.13): Establishment and progress report. Technical Report 018. B.C. Ministry of Forests., Research Branch, Victoria, B.C. http://www.for.gov.bc.ca/hfd/pubs/Docs/Tr/Tr018.htm

The key difference between E.P. 886.13 and other lodgepole pine fertilization studies in the BC interior was the inclusion of two treatments involving annual fertilizer applications; see Brockley and Simpson (2004) for full details.

Early tree responses to the fertilization treatments at two lodgepole pine installations, including Kenneth Creek, were presented in:
Amponsah, I.G., P. G. Comeau, R.P. Brockley, and V.J. 2005. Effects of repeated fertilization on needle longevity, foliar nutrition, effective leaf area index, and growth characteristics of lodgepole pine in interior British Columbia, Canada. Canadian Journal of Forest Research 35: 440 – 451. https://doi.org/10.1139/x04-200

Prior to his retirement, Brockley published a comprehensive report on the results of the lodgepole pine installations in this study:
Brockley, R.P. 2010. Effects of intensive fertilization on the foliar nutrition and growth of young lodgepole pine forests in the British Columbia Interior: 12-year results. Technical Report 058. B.C. Ministry of Forests and Range., Forest Science Program, Victoria, B.C. http://www.for.gov.bc.ca/hfd/pubs/Docs/Tr/Tr058

The Kenneth Creek installation, approximately 60 km ESE of Prince George, was established in 1993 in a 10-year-old lodgepole pine plantation. [Note that this site is also referred to as the "Bowron" site in some documents and filenames.] The site was located on a flat glacial outwash terrace with fairly uniform deep sandy soils, and was extensive enough that it later hosted one of two installations of E.P. 886.15 established in 2001. (See https://search.nbca.unbc.ca/index.php/2023-2-2-1-3.) 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.

Dr. Paul Sanborn's involvement in this study addressed three aspects of soil and nutrient cycling responses to the fertilization treatments:

  1. mineral soil and forest floor nutrient stocks, (Sub-subseries 2023.2.2.15.1)
  2. litterfall amounts and chemical composition, and, (Sub-subseries 2023.2.2.15.2)

During the 1980s, Agriculture Canada pedologists Scott Smith (retired from Summerland Research Station, formerly based in Whitehorse) and Charles Tarnocai (retired from Central Experimental Farm, Ottawa) had a large field program which addressed the trends in soil development in the central Yukon. Across this region, particularly between Whitehorse and Dawson City, the land surfaces and surficial deposits vary greatly in age due to the differing extents of glaciations over the past ~2 million years.

This work built on a pioneering study from the previous decade:

Tarnocai and Smith presented their results in two publications:
