Summary:
The objective of this work is to make physical measurements of the size, shape and distribution of earth hummocks in areas where the 1968 forest fire did not occur. We are developing a mathematical model which predicts hummock size and activity based on soil properties and environmental conditions. Because hummock activity appears to be very sensitive to environmental changes, our model, coupled ...

Summary:
Since fire is most wide spread agent of change in the northern forest, society should know how climatic warming will influence the force. The fire history of the Mackenzie Delta Region is known only through fire suppresion records over the past 25 years. Spot checks on the landscape have been made, but no longer record of 5-20 decades is available. Tree ring approaches will be used in this study...
