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...

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 ...

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: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....

19911990 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....
