Ddhaw Ghro is an isolated mountain range in central Yukon. The area has been important to Northern Tutchone people for thousands of years. It has several features of regional significance, including unglaciated alpine areas and plant communities. It is also known for the Chu Tthaw Hot Springs, the fannin sheep population, the rich cultural history of the Northern Tutchone People and the intact mountain ecosystem. In 1948, the government of Canada established the Ddhaw Ghro area as the McArthur Game Sanctuary. Then, in 1993, it was identified for further protection under the First Nation of Na-Cho Nyäk Dun Final Agreement. ... As part of the Selkirk First Nation Final Agreement, a Ddhaw Ghro steering committee was...

A systematic water-quality study of the Fortymile River and many of its major tributaries in eastern Alaska was conducted in June of 1997 and 1998. Surface-water samples were collected for chemical analyses to establish regional baseline geochemistry values and to evaluate the possible environmental effects of suction-dredge placer gold mining and bulldozer-operated placer gold mining (commonly referred to as “cat mining”). In general, the water quality of the Fortymile River is very good, with low total dissolved solids and only two cases in which the concentration of any element exceeded primary or secondary drinking-water quality standards. In both cases, iron exceeded secondary drinking-water limits. At...

This dissertation presents results from four recently discovered archeological sites in southcentral Alaska. The sites range from the Younger Dryas to middle Holocene in age and provide valuable contextual information for the human process of colonizing a region that was heavily glaciated during the LGM. The deglaciation and human colonization of southcentral Alaska is one of the most significant aspects of the settling phase in eastern Beringia not only for its potential to inform about the human response to post-glacial landscapes but also for what we can learn about subsequent migrations to the southern coast of Alaska. Understanding how early foraging societies spread throughout eastern Beringia, after its initial...

In the Yukon Territory and District of Mackenzie, coal-bearing strata, ranging in age from Mississippian to Oligocene, have been found in some 27 areas. In the Yukon, such rocks underlie 37,000 km2, while in the District of Mackenzie, 3000 km2 are believed to contain coal in the Brackett Basin alone, with additional potential in the Liard River, Godlin Lake and Great Bear Lake areas. The three most important basins are the Whitehorse Trough and Bonnet Plume Basin in the Yukon Territory and the Brackett Basin in the District of Mackenzie. In the Whitehorse Trough, coal exploration has been carried out at Mount Granger near Whitehorse and at Division Mountain, west of Braeburn. Coal mining has been actively carried...

The general goal of this research was to address the broad question, does consensus work in resource management decision-making? Its purpose was to identify success factors for employing the consensus decision-making model specifically in land use planning; to examine the models incepted by the government of British Columbia during the period 1992–1995; and to investigate the application and effectiveness of the models as actually employed in integrated resource planning in British Columbia. The specific objective was to develop a general diagnostic framework for evaluation, based on indicators and success factors derived from a review of pertinent literature; from interviews with stakeholder participants in these...

A logical starting point for climate change adaptation in the forest sector is to proactlvely identify management practices and policies that have a higher likelihood of achieving management objectives across a wide range of potential climate futures. This should be followed by implementation of these options and monitoring their success in achieving management objectives within an adaptive management context. Here, we implement an approach to identify locally appropriate adaptation options by tapping into the experiential knowledge base of local forest practitioners while at the same time, building capacity within this community to implement the results. We engaged 30 forest practitioners who are involved with...

Several studies have documented the potential and existing environmental degradation due to all-terrain vehicle (ATV) use in sub-arctic terrain. Impacts include vegetation damage or destruction, changes in vegetation community composition and structure, substrate thermal change and permafrost thaw, and soil erosion and subsequent development of thermokarst features and terrain degradation. One of the most evident effects of prolonged ATV use in sub-arctic tundra is the development of extensive trail braiding. Trail braiding results from alternate trails that are created by users in order to avoid mud bogs and standing water (ponding) that develop on ATV trails which are underlain by ice ridge permafrost. One option...
