Understanding the Interactions between Wildfire Disturbance, Landscape Hydrology and Post-Fire Recovery in Boreal-Taiga Ecosystems
chercheur principal: Bourgeau-Chavez, Laura L.
Année(s) de permis: 2019
Résumé: The overall goal of the research is to improve understanding of the controls and impacts of a changing climate on the vulnerability and resiliency of boreal-taiga ecosystems to wildfire. This is being addressed through field sampling and process-based ecological and hydrological modeling of the 2014-2016 wildfires of southern NWT. To conduct the proposed research, the research team will addres...

Studies of the environmental effects of disturbances in the subarctic (SEEDS)
chercheur principal: Kershaw, G. Peter
Année(s) de permis: 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Résumé: The main study objective is to describe post-fire ecosystem responses in a subarctic forest. Access to the site will be along existing seismic lines from Tulita. Transport will involve helicopter, boat, ATV and foot. The research camp consists of tents on frames and on platforms and a food and equipment cache contained within a solar-powered electric shock fence (bear fence). Sleeping tents are o...

Forestry Research in the Gwich'in Settlement Area
chercheur principal: Walker-Larsen, Jennifer
Année(s) de permis: 2003 2002 2001 2000
Résumé: Forest Fire Effects on Vegetation and Wildlife Habitat use: Research sites will be accessed by helicopter. Sites are located in burns of different ages. In the summer, small teams will complete vegetation plots, assess species composition and percent cover, and assess wildlife abundance. In the winter, helicopter track surveys will be completed. Forest Monitoring (ARNEWS and SI/MAB plots): The...

Post-fire decomposition of woody material and post-fire habitat structures in the western Canadian boreal forest.
chercheur principal: Sander, Barbara
Année(s) de permis: 1997
Résumé: Burned areas of different ages have been identified from fire-history maps and data bases provided by the Forest Management Division of the NWT in Fort Smith. Chosen fires are located along the Highways 1, 2 and 5. Access and transportation will therefore be by car/truck. The exact location of the sites will be documented by using GPS-equipment. A total of three sites (Jack Pine, Black Spruce ...

Modelling the establishment and growth of post-fire tree seedlings
chercheur principal: Gal, Ruth Ann
Année(s) de permis: 1993 1992
Résumé: As a result of global warming (which results from increased amounts of carbon dioxide in the atmosphere), it is suggested that the number of forest fires and the amount of area burned may increase in the northern boreal forests. The types of trees that grow first in these burned areas may be different from those that would have grown in if the climate was cooler. I will collect data at burn site...

Climate Change at the Forest/Tundra Boundary
chercheur principal: Landhaeusser, Simon M.
Année(s) de permis: 1992 1991 1990
Résumé: The Researcher will study regions of past burned areas south and north of Inuvik to determine if post-fire spruce establishment has occured not only on areas formally dominated by spruce, but also on larger areas that were formerly tundra....

Re-evaluation of Disturbance Experiments in the Lower Mackenzie Region, NWT
chercheur principal: Wein, Ross
Année(s) de permis: 1993 1992 1989 1988 1987
Résumé: In the early 1970's, several test plots were established to see what happens when the plants and soil are disturbed or removed by fire, oil spills, and vehicles. Dr. Wein and two students will be re-visiting these sites to document how the plants have recovered since that time....
