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 sites will be contained within a 1 km corridor with 'bulges' in areas of special concern such as river crossings. Surveying sites accessed by helicopter, boat, vehicle and/or on foot. To avoid c...

Summary: 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...

Summary: This project will take place in Tuktuk Nogait National Park in 1998 and 1999. The objective of the project is to map the vegetation of the park. As many areas of the Park as possible will be hiked and the various vegetation communities along the hiking route will be put into one of several classes, and their exact geographical location recorded. Once the field season is over, these various geograp...

Summary: As part of overall reclamation goals of BHP, the 1996 season will focus on three components. Vegetation response will be assessed in August using the point-frame method. Within the legume, indigenous seed and shrub cutting plots, plant density will be recorded. Soil samples in replicates of three will be collected from each treatment to analyze physical and chemical characteristics. Secondly, ...

Summary: The aim of the Sverdrup Pass Project is to learn how vegetation returned to the artic realm after the retreat of the continental ice sheet (8000 years ago) and the prospect of the land becoming green if climate warms. The Itex project is geared to the effect of climate warming on the vegetation. The snow-fence study at Baker Lake is concerned with the effects of long-lying snow deposited on both s...

Summary: The researchers want to determine the age of the isolated "tree islands" and how they manage to grow so far from the treeline. Researchers look for old stems for carbon dating, and map the position of each stem. The age and growth rates of the trees are determined by counting and measuring tree-rings. This year plant communities found on south-facing slopes down the Anderson River will be studied....

Summary: 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...

Summary: The researchers will participate in and assist with fire behavior and fuel type data collection on the Little Rat Lake prescribed burn. The will resurvey the experimental burn plots and carry out a regeneration survey 10 years after the experimental burns at Porter Lake. Initial attack crew leaders in the Fort Simpson district will be interviewed to obtain detailed information about the effectiven...

Summary: The research will document long-term recovery rates on permanent research plots that were established on a range of tundra disturbances. In the 1970's disturbance surveys and experiments on a wide range of topics provided short-term results and predictions on recovery rates. This project will collect comparable data to validate these short term predictions and will also help to develop some ideas ...

Principal Investigator: Forbes, Bruce C.
Licensed Year(s): 1990 1988
Summary: Bruce Forbes is looking at how quickly plants are invading the old settlement of Clyde River where the ground was cleared for buildings and roads. This site will be compared to undisturbed ground and similar disburbances at other human occupancy sites within the High Arctic....
