Past and future fire dynamics: implications for central arctic caribou and dependent communities (Community based component)
chercheur principal: Jacobsen, Petter F
Année(s) de permis: 2010 2009
Résumé: This licence is being issued for the scientific research application No.1294. The research is part of the larger research project on the correlation between increased forest fires and decreasing caribou population in the Northwest Territories. The intent is to record TEK concerning environments rebounding from forest fires, the correlation between these areas and the caribou population,...

Changing fire regimes in northern coniferous forests
chercheur principal: Wallenius, Tuomo H
Année(s) de permis: 2009
Résumé: This licence is being issued for the scientific research application No.1103. The research objective is to study the occurrence of forest fires in Northern Canada during the past 200 years. They are especially interested in large scale averages and changes in the estimated fire return intervals/annually burned proportions of the landscape. Specific research questions are: 1. How often for...

Post-fire forest regeneration in the Western Canadian continental boreal forest: measurement and landscape modeling
chercheur principal: Gal, Ruth A.C.
Année(s) de permis: 2005
Résumé: The objective of this study is to develop a landscape model capable of predicting regeneration after fire in the Northern Boreal Forest. Data has been collected in the past from Porter Lake (near Lutsel K'e), Big Fish Lake, Alberta, and Wood Buffalo National Park, between Pine Lake and Peace Point. Data has also been collected from the International Crown Fire Modeling Experiment near Fort Pro...

Forestry Research Projects in the Gwich'in Settlement Area: Seismic Line Revegetation in the Gwich'in Settlement Area (GSA)
chercheur principal: Van Gerwen-Toyne, Melanie
Année(s) de permis: 2003 2002 2001 2000
Résumé: Baseline data on the rate of tree growth (productivity) and time required for trees to re-establish (regeneration) following fires and anthropogenic disturbances are required to determine forest sustainability and understand how habitat changes over time...

Prescribed Fire and Wildlife Habitat Enhancement
chercheur principal: De Groot, Bill
Année(s) de permis: 1994
Résumé: Plant samples will be collected in the field by the researcher after they become dormat for treatment in a lab experiment. Burning treatments will be conducted in the lab where environmental growing conditions and the plant physiological state at the time of the treatment can be better controled. This will be done in order to model the effects of fire on two types of shrubs....

Fire, carbon budget and climate change
chercheur principal: Wein, Ross
Année(s) de permis: 1993
Résumé: The research team will be examining areas of permafrost south of Inuvik and near Hay River in order to assess the rate of loss of permafrost as a result of the warming in climate over the past twenty years. The loss in permafrost may be speeded up following a local fire. The wetlands that replace these areas of permafrost could lead to a greater production of methane (one of the gases that contr...

A Northern Forest Ecosystem Simulation Model of Early Post-Fire Tree Seedling Establishment, Growth and Competition
chercheur principal: Gal, Ruth Ann
Année(s) de permis: 1993 1992
Résumé: The researcher and her team will glean physiological rates and relationships for tree growth from the literature and substitute the data into a functional model, which will be calibrated against intensive sampling within WBNP over dry, mesic and wet landscapes....

Fire Severity and Growth of Treeline Tree Species: Climate Change Implications
chercheur principal: Olsen, Sue K.
Année(s) de permis: 1992
Résumé: The experiment will determine the interacting effects of fire severity, soil moisture and air temperature treatments on the emergence, winter survival and initial growth of treeline and near treeline tree species. The availability and viability of tree seed for successful regeneration of the treeline and near-treeline tree species will also be determined....

Digital Database of Vegetation Types of the Mackenzie Valley Development Corridor
chercheur principal: Squires Taylor, Cindy
Année(s) de permis: 1992 1991
Résumé: The Researcher will conduct a survey, approximately 30 km on either side of the Mackenzie River using satellite imagery. A classification will be undertaken of the area from the Mackenzie Delta to the Fort Simpson area, with wider zones along the east side to include proposed pipeline routes. The information can be plotted as colour maps to show the location of trap lines, forest fires or wildlife...
