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 research objective is to show that the fertility of black spruce (Picea mariana) in the Arctic is limited by the amount of pollen in the surrounding air.
After snowmelt, the researchers will choose unburned black spruce “islands” at different distances from the perimeter of the 1999 Lynx Creek fire. Subsequently, as the developing black spruce pollen cones become easy to see, they will remo...

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 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....
