Fort Selkirk volcanic field, Yukon

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:
Sanborn, P., 2010. Soil reconnaissance of the Fort Selkirk volcanic field, Yukon (115I/13 and 14). In: Yukon Exploration and Geology 2009, K.E. MacFarlane, L.H. Weston and L.R. Blackburn (eds.), Yukon Geological Survey, Whitehorse, Yukon. pp. 293-304. [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.]

Paleosols at the Lost Chicken Mine, Chicken, Alaska

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.

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.

Soils Research at Kluane Lake, Yukon

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

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

"Managing Conservation Lands to keep Nature's Pulse Beating" speech by Gary Runka

File consists of a speech given by Gary Runka entitled "Managing Conservation Lands to keep Nature's Pulse Beating" for the BC Trust for Public Lands.

Commentary on this speech by Barry Smith of the Ministry of Agriculture and Lands:
"GGR's was the opening address at the workshop. While this speech is focused on the issue of Best Management Practices (BMP), comments about the ALR are woven into the presentation. This copy of the speech appears to be a draft version and includes several hand-written amendments with some points crossed out.

In the opening, mention is made of the grounding that the 2008 document "Taking Nature's Pulse: the Status of Biodiversity in British Columbia" has provided the workshop.

This speech provides an historical overview of the broader provincial context of BMP's drawn from 40 years of GGR's experience. The following is a selection of his comments:

  • BMP's are part of the "tool kit" of policy and management mechanisms that have been experimented with over the decades to try to rationalize human economic activities with the needs of other species and overall ecosystem well-being.
  • Historically the 1960s and 70s Canada Land Inventory program that emerged from the Resources for Tomorrow conferences was a significant benchmark mapping land capability for agriculture, forestry, recreation, wildlife and waterfowl use (of which GGR was centrally involved).
  • Within BC, using the CLI, the 1973 Land Commission Act authorized the establishment of a provincial zone to protect those sacred lands with the biophysical capability to grow food.

One point was not used in the speech (crossed out). The speaking notes, however, include a reference to the Land Commission legislation originally having a complimentary conservation objective that had since been removed. GGR makes the point that still having the conservation function may have contributed positively to current struggles to preserve natural habitat. Regardless, it is noted that the concept of the ALR has been a unique, effective and, most importantly a lasting management practices tool for conserving lands identified as biophysically significant.

A further selection of points made:

  • We need to evolve BMP tools that are adaptable yet resilient in the face of changing knowledge, climate change and ever-evolving social priorities.
  • Traditionally, planning has been most associated with local governments in the form of official community, regional and neighbourhood plans and as an outgrowth of the ALR - Agricultural Area Plans.
  • Environment Farm Planning - by agreeing to engage in the conservation planning process, participating farmers and ranchers have qualified for funding to carry out farm improvements benefitting conservation and biodiversity.
  • The work of the Delta Farmland and Wildlife Trust is outlined (p. 8)
  • "My final words of wisdom are - Be focused and be pragmatic"
  • "Many of the best intentions to standardize land management practices for conservation lands have been great on paper - but never quite make it on the ground."
  • And, if BMP are not implemented effectively on the ground, they cannot play the critical role they need to play in 'keeping nature's pulse beating'."

Agriculture Canada pedological research in the central Yukon

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:
Foscolos, A.E., N.W. Rutter, and O.L. Hughes. 1977. The use of pedological studies in interpreting the Quaternary history of central Yukon Territory. Bulletin 271. Geological Survey of Canada, Ottawa. 48 p.

Tarnocai and Smith presented their results in two publications:
C. A. S. Smith, C. Tarnocai, and O. L. Hughes. 1986. Pedological investigations of Pleistocene glacial drift surfaces in the central Yukon. Géographie physique et Quaternaire, 40 (1): 29–37.
Tarnocai, C. and C. A. S. Smith. 1989. Micromorphology and development of some central Yukon paleosols, Canada. Geoderma 45 (2): 145-162.

Tarnocai and Smith shared the unpublished data and soil samples from this work with Dr. Paul Sanborn, and this resulted in a student project published as:
Daviel, E., P. Sanborn, C. Tarnocai, and C.A.A. Smith. 2011.Clay mineralogy and chemical properties of argillic horizons in central Yukon paleosols. Canadian Journal of Soil Science 91: 83-93.
