Growth Conditions and Vitality of Sphagnum in a Tundra Community Along the Alaska Pipeline Haul Road
Effects of road dust and road related construction upon Sphagnum lenense were found in one Sphagnum-rich tundra community along the Alaska Pipeline haul road. Dust, arising from vehicular traffic, settled in greatest quantities near the road with the amount rapidly decreasing away from the road. Wat...
