2008 Résumé:
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...

Résumé:
As part of an on-going study, this research will involve collecting cores from trees located in the Campbell-Dolomite Uplands (near Campbell Lake). This data will be added to data collected in other locations (past studies) in order to determine how past climate has influenced the growth of trees (as indicated by tree rings within the tree trunk). The research is helpful in trying to understand ...

19911990 Résumé:
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....
