Objective(s): To determine and document the maximum size of treeline species that has been possible under recent climates by slope and direction; to experimentally determine the success of tree seedling growth on different slopes and aspects and relate this to the energy input; to document how vegetation recovery processes change over time on slumped areas in valleys along the Caribou Hills.

Project Description: To determine the maximum size of treeline tree species in a burned and unburned valley in the Caribou Hills, the mass of standing trees on different slopes and aspects will be estimated and related to the energy input. In 1992 the plots prepared in 1990 and planted and seeded in 1991, will be revisited and measurement of growth for the second growing season will be taken.
