The contents of this report include: an update on Board membership and staff; a description of the draft implementation strategy to the Plan; the Planning Board's priorities for 2004-2005; a review of land use permits and water licences issued, and an explanation of how an approved Plan has affected those acivities; a list of action items that are currently being addressed; recommendations for groups to consider in the next year; the Planning Board's work plan for 2003-2004, and; the audited financial statements for 2003-2004. ... All regulatory agencies have to ensure that all licensed, permitted, and othe authorized activities related to the use of land, water, and the deposit of waste conform with the Plan. The...

This thesis investigates the theory and practice of integration in resource and environmental management. Research on integration is growing as a result of the escalating demands placed on resources, an increase in the quality and quantity of information available concerning the environment, and the increased involvement and coordination of partners and participants in resource and environmental decision-making. Focus is placed on several resource and environmental management processes in the Southwest Yukon, including wildlife management, protected areas management, forest management and environmental assessment. A case study approach is utilized to examine the perception and practical application of integration...

Lake sediment cores collected from four lakes (Upper Fly Lake 61.04°N, 138.09°W, 1326 m a.s.l.; Jenny Lake 61.04°N, 138.36°W, 817 m. a.s.l.; Donjek Kettle 61.69°N, 139.76°W, 732 m a.s.l.; Lake WP02 61.48°N, 139.97°W, 1463 m a.s.l.) in the southwest Yukon provide records of postglacial climatic variability in the region. A 13,000 year pollen record from Upper Fly Lake indicated that herbaceous tundra existed on the landscape from 13.6 to 11 ka, followed by birch shrub tundra until 10 ka, when Picea forests were established in the region. Pollen-, chironomid-, and ostracode-inferred paleoclimate reconstructions showed a long-term cooling with increasing moisture from the late glacial through the Holocene. The early...

In glacier-fed systems climate change may have various effects over a range of time scales, including increasing river discharge, flood frequency and magnitude. This study uses a combination of empirical monitoring and modelling to project the impacts of climate change on the glacial-fed Middle Fork Toklat River, Denali National Park, Alaska. We use a regional calibration of the model HBV to account for a paucity of long term observed flow data, validating a local application using glacial mass balance data and summer flow records. Two Global Climate Models (HADCM3 and CGCM2) and two IPCC scenarios (A2 and B2) are used to ascertain potential changes in meteorological conditions, river discharge, flood frequency...

Nutritional restrictions in winter may reduce the availability of protein for reproduction and survival in northern ungulates. We refined a technique that uses recently voided excreta on snow to assess protein status in wild caribou (Rangifer tarandus) in late winter. Our study was the first application of this non-invasive, isotopic approach to assess protein status of wild caribou by determining dietary and endogenous contributions of nitrogen (N) to urinary urea. We used isotopic ratios of N (?15N) in urine and fecal samples to estimate the proportion of urea N derived from body N (p-UN) in pregnant, adult females of the Chisana Herd, a small population that ranged across the Alaska-Yukon border. We took advantage...
