Main objective of the field work is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. Additional objective is to conduct a regional study of stand development and its relationship to environmental factors in a several-square-kilometer study area of mostly black spruce.
Five methods will be used. 1) Soil and air temperature will be measured...

Summary:
The researchers will measure black spruce forests along the Dempster Highway. They will determine if the trees can only grow to a certain limit that cannot be surpassed, regardless of the number of trees per hectare. A limit of this kind was recently discovered in Siberia.
The number of trees per hectare and above-ground biomass will be estimated in numerous black spruce stands. A method ...

Summary:
The main objective of the proposed research is to collect extensive data of tree size and stand density from mixed forests of Jack pine and quaking aspen in Wood Buffalo National Park and to examine theoretically the patterns of quantitative forest development with special reference to the phenomenon of 'natural thinning' in even-aged forests. The research team consisting of forest ecologists will...

1997 Summary:
The research team will consist of forest ecologists. We plan to study a few jack pine stands by taking stem samples for examination of forest growth that occurred in the past. A possible effect of climate change on the growth of forests are being examined. Several trees were cut and were analyzed last year. This summer several additional stems will be sampled. When a tree is cut, we try not to dis...

Summary:
The researcher will conduct research on jack pine forests along the highways in Wood Buffalo National Park and will also collect stem increment cores from black spruce trees around the latitudinal tree line near Inuvik. This research will consist of remeasurement of permanent plots, foliage distribution and light measurement, establishment of pruning experiment and stem core sampling near Inuvik....

The Researcher will measure stem diameter and height of individual trees representing ages five to sixty years. Approximately 15 small individual jack pines will be cut to estimate dry weights and measurements of light conditions in various jack pine stands will be undertaken....
