Description
Summary:Environmental and floristic evidence is presented to show that, after removal of the White Spruce ( Picea glauca ) and willow-alder ( Salix spp.–Alnus crispa ) canopies from exposed sites within the boreal woodland of the Mackenzie River Delta, Northwest Territories, Canada, environmental degradation is such that secondary succession of low-arctic tundra heath, mosses, and lichens, takes place. The extreme exposure of cleared sites enables a hardy group of tundra plants to compete with the local flora and invade the previously forested location.
