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 objective is to quantify the amount of fuel combustion and carbon losses during wildfires in boreal conifer forests and peatlands. These data will allow us to quantify climatic and weather controls on the severity of biomass burning.
Boreal forests and peatlands store a large amount of carbon in vegetation and soils. Climate change is predicted to increase summer drought, which could mak...

Summary:
This licence is being issued for the scientific research application No.1103.
The research objective is to study the occurrence of forest fires in Northern Canada during the past 200 years. They are especially interested in large scale averages and changes in the estimated fire return intervals/annually burned proportions of the landscape.
Specific research questions are:
1. How often for...

Summary:
A network of permanent monitoring plots (PMPs) is required for assessing forest growth and yield in the NWT. These PMPs will be used to: 1) obtain information to assess the rate of forest growth and determine current and potential yield of various fores...

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...

1997 Summary:
The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...

Summary:
The study area will be sampled on a 2x2 km grid as the vegetation type of the area in question is predominantly jack pine. At each 2 km interval 3 procedures are done: 1) plant identification and % cover of each species in approx. 100 m. sq., 2) tally of the fuels (logs, twigs, branches) that fall along a triangular transect, 3) discs are removed from one large unscarred tree and one scarred tree...

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....

1992 Summary:
As a result of global warming (which results from increased amounts of carbon dioxide in the atmosphere), it is suggested that the number of forest fires and the amount of area burned may increase in the northern boreal forests. The types of trees that grow first in these burned areas may be different from those that would have grown in if the climate was cooler. I will collect data at burn site...
