Summary: This project will assess the sulphur dioxide impacts of a natural gas well production test on vegetation in complex, steep terrain and establish a biomonitoring system for tracking changes in vegetation health in the vicinity of a natural gas well. Well...

Summary: Baseline data on the rate at which trees grow (productivity) and the time required for trees to re-establish (regeneration) following fires and human disturbances are required to determine forest sustainability and to understand how habitat changes over...

Summary: This study examines (1) the regeneration dynamics of White spruce in the Mackenzie Delta and Black spruce on seismic lines; (2) the potential for seeds to disperse on snow; (3) pollen dispersal; and (4) pollen production. Study sites in the Mackenzie D...

Summary: The long distance dispersal of tree pollen and seeds is of considerable interest as we ask how fast plants can migrate in response to rapid climate change. Examination of seed dispersal will actually be based on looking at germinants (rather than seeds)...

Summary: The vegetation component of the 2002 baseline studies will focus on completion of the vegetation typing surveys. Initially, a reconnaissance flight will be required along the study corridor. This flight will be used to identify sites for detailed sampling. Sites will be selected to represent the major ecological land units. Where possible, sample sites will be grouped to reduce helicopter time....

Summary: The BC Terrestrial Ecosystem Mapping inventory standard will be used to provide a uniform method of describing vegetation, soil and terrain based on air photo interpretation and field data collection. The sampling sites will be located on Crown Land contained within a 1 km corridor with 'bulges' in areas of special concern such as river crossings. Surveying sites accessed by helicopter, boat, veh...

Summary: The proposed vegetation, forestry and soil survey program involves surveying sites accessed by helicopter and boat. Due to traditional hunting activities along the northern edge of the Mackenzie Delta, the vegetation, forestry and soil survey will avoid the northern end of Kendall and Richards Islands during the harvest period. If it is necessary to enter this area prior to this time (in the even...

Principal Investigator: Jagels, Richard
Licensed Year(s): 2000
Summary: The NWT component of this study is to examine how the anatomical features of wood from the genus Larix, vary with changes in latitude. This will be compared to work done on Axel Heiberg Island, Nunavut where a fossil forest of mummified wood approximately 45 million years old was found. Certain features of wood can provide clues to assess winter temperatures but these features vary with latitude....

Principal Investigator: Osawa, Akira
Licensed Year(s): 2000
Summary: The main objective of the proposed research is to collect extensive data of tree size and stand density from mixed forests of Jack pine and quaking aspen in Wood Buffalo National Park and to examine theoretically the patterns of quantitative forest development with special reference to the phenomenon of 'natural thinning' in even-aged forests. The research team consisting of forest ecologists will...
