Developing Sustainable Non-timber Forest Product Business Opportunities in the GSA
Principal Investigator: Boxall, Peter
Licensed Year(s): 2001 2000
Summary: The distribution and abundance of some potential non-timber forest products (berries) will be assessed based on the results of community interviews and field studies. The number of berries in various forest stands in the Gwich'in Settlement Area will be quantified. No berries will be picked. Berries will be quantified by counting by hand. Sites for berry counting will be accessed by boat or road....

Hybridization and genetic variation in arctic grasses: molecular, morphological and ecological evidence
Principal Investigator: Gillespie, Lynn J.
Licensed Year(s): 1997 1995 1994
Summary: The researcher will collect living plants (Arctic grasses), 6 - 10 species from each collection site. In addition, several plants of each species will be pressed and dried as voucher specimens to be used to check the identification. Photographs of the plants and their habitats will be made. In Ottawa, variations in DNA among different populations and species will be analyzed to study species re...

Palynology (Mackenzie Valley Global Change), study of the climatic change along the Mackenzie River and on the Arctic Islands.
Principal Investigator: Jette, Helene
Licensed Year(s): 1995 1993 1992
Summary: The researcher will sample a variety of lakes (some 50 lakes altogether) around Inuvik. A hole, approximately 8 inches in diameter, will be bored through the ice in each lake. Using an Ekman sampler, lake bottom sediments (mud) will be collected for analysis in the lab. The researchers will get to each of the lakes bt helicopter and spend approximately 15 to 20 minutes at each lake....

Prescribed Fire and Wildlife Habitat Enhancement
Principal Investigator: De Groot, Bill
Licensed Year(s): 1994
Summary: 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....

Long-term forest-tundra disturbance research
Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: In previous research in the 1970's, experiments and surveys provided information on the recovery rates of vegetation in response to disturbances from human activities. Several predictions about the long-term recovery of vegetation were made at that time. We are now collecting data to determine if these predictions reflect what is actually occurring. This information provides information about l...

Grasses of the NWT
Principal Investigator: Aiken, Susan
Licensed Year(s): 1993 1992 1991
Summary: The researcher will continue her study on NWT grasses. She will collect living plants in order to conduct chemical analyses on the plant tissue. These tests will help to identify different species of grasses (especially those that look very similar) and also help to determine where these species originated from. In addition, the researcher has small experiments on grass being conducted by staff...

Arctic timberline ecology
Principal Investigator: Broll, Gabriele
Licensed Year(s): 1993
Summary: As part of his trip to Inuvik with the International Tour of Permafrost Affected Soils, the researcher will record information about the ecology (including local climate conditions, soil conditions and plant communities) of the timberline at selected sites visited during the Tour. These sites are located along the Dempster Highway near Inuvik....

Fire Severity and Growth of Treeline Tree Species: Climate Change Implications
Principal Investigator: Olsen, Sue K.
Licensed Year(s): 1992
Summary: 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....

Climatic Change at the Forest-Tundra Boundary
Principal Investigator: Landhaeusser, Simon M.
Licensed Year(s): 1992 1991 1990
Summary: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken....

Vegetation Response to Global Warming in the Mackenzie River Basin: Interations Between Northern Boreal Forests, Wetlands and Regional Hydrology
Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...
