Objectif(s): To evaluate the reliability of using spectral data collected by orbiting satellites to identify dominant vegetation types within the forest to tundra ecotones; to measure the parameters that characterize this vegetation both spatially and spectrally; to test and hypothesis that the reflectance characteristics of tree density and the composition of the ground surface vegetation can be used to detect early responses to climate change.

Description du projet: The Researcher will continue to determine what density of trees is necessary for detection by the satellite sensors. To determine what are the densities of shrubs and herbs or dwarf shrubs and lichens that change the reflectance patterns from the understory. To determine if the thresholds in density will be sensitive enough to monitor vegetation responses to climate change in the forest to tundra ecotones with satellites.
