Licensed Year(s): 2024 2023
Summary: This licence has been issued for the scientific research application No. 5947. The aim is to monitor vegetation changes in current climate warming for simulating past and future dynamics with an individual-based spatially explicit model (LAVESI). Therefore, our intentions are: 1. assessing stand inventories at diverse bioclimatic and environmental settings by a space-for-time approach 2. gat...

Summary: “Environmental Studies across Treeline (ESAT) in the Mackenzie Delta region” is a northern based collaborative program with an objective to enhance the understanding of environmental conditions in the Mackenzie Delta region through scientific studies and monitoring. Specific studies include: 1) monitoring permafrost conditions in the Mackenzie Delta region; 2) examining freeze-back of the active l...

Principal Investigator: Green, Scott
Licensed Year(s): 2009 2008
Summary: The project will examine past tree growth patterns at the northern treeline in Western Canada as a baseline to predict future growth responses to climate change. Additionally, the researchers will examine tree regeneration and plant associations at the northern treeline. Annual tree rings represent a growth response to local climate. Wide growth rings represent good growing conditions, and nar...

Principal Investigator: Johnston-Schuetz, Cheryl
Licensed Year(s): 2007
Summary: The objective of this project is to examine the environmental thresholds to the successful establishment of a boreal (high latitude) conifer forest by measuring photosynthetic rates in conifer seedlings. Climate change has the potential to shift southern commercial tree species and treelines northward with implications for existing ecosystems and future economic development. The project’s goal ...

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....

Principal Investigator: Pearce, Cheryl M.
Licensed Year(s): 1993 1992 1991 1990
Summary: The researcher will complete the intensive sampling of the Arctic Coastal Plain west of Shallow Bay on the Mackenzie River Delta to the Alaska border, where tundra surfaces could differ from those east of the Mackenzie Delta, high arctic tundra on northern Cape Bathurst, and additional treeline sites between Inuvik and the Horton River....

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....

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....

Principal Investigator: Luckman, B.H.
Licensed Year(s): 1989
Summary: Dr. Luckman and one assistant will look for potential sites for the Geological Survey of Canada to study global change. They will also obtain recent tree-ring chronologies from treeline sites in the Mackenzie Delta....
