Summary: 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: Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The research team will...

Summary: With the assistance of NWT Dept. of Renewable Resources fire management personnel, a study site was located approximately 50 km north of Fort Providence. A dense jack pine stand occupies the site. Surrounded by marshland, this site is ideally suited to supporting the high-intensity crown fires required in this study. Ten burning plots were located in this site. Firelines approximately 50 m wide w...

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....

Licensed Year(s): 1993 1992
Summary: The researcher and her team will glean physiological rates and relationships for tree growth from the literature and substitute the data into a functional model, which will be calibrated against intensive sampling within WBNP over dry, mesic and wet landscapes....

Summary: The researcher and his team will estimate the number of trees and monitor individual growth in flagged and tagged stands, as well as estimating foliage weight of individual trees. They will measure light conditions in various jack pine stands, as well as collect stem cores to be analyzed and compared with stem cores from other parts of the northern hemisphere for the possibility of accelerated gr...

Principal Investigator: Wein, Ross
Licensed Year(s): 1989
Summary: Dr. Wein and his assistant will plant jack pine seedlings in the Reid Lake and Sandy Lake area where the dry conditions simulate a drought. They hope to find a species of jack pine which will survive drought conditions in more southern forests....

Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1989 1988
Summary: Dr. Glen MacDonald and his team will be obtaining lake sediment cores, samples of pine needles, cones, seeds and tree-ring cores from 2 sites near Hay River. Fossil pollen from the sediment will be used to document the chronology of pine migration into the NWT following the last ice-age. The study will be used to understand postglacial history of northern plants....

Principal Investigator: Wright, Robert A.
Licensed Year(s): 1988
Summary: to describe the differences in seedling drought resistance between jack pine populations from the geographic and environmental extremes of the range...
