Study in Ecology: The Decline of the Sugar Maple
This audio lecture features scientists who examine the unusually high mortality rate of sugar maple and red spruce trees as a means of illuminating broader issues affecting forests of the Northeastern United States. The scientists discuss the decline of these species and whether it is a local phenomenon, or if it is indicative of larger regional-scale disturbances. Data is presented from study stands on the Allegheny Plateau. The contributing factors that are stressing the trees, and how nutrients are affecting the health of stands are also studied. The audio lecture is 1 hour and 5 minutes long.
