NSRC researchers investigated relationships among nonnative invasive plants, soil drainage, tree canopy openness, and harvest type and intensity in a mixed conifer forest on the Penobscot Experimental Forest in Maine. Researchers studied 20 forest stands, managed using various long-term silvicultural treatments (including no harvest), and 2 additional unmanaged stands on former agricultural sites. They measured density and percent cover of woody plants up to two feet tall, herbaceous plants, mosses, liverworts, and lichens. Percent canopy openness was determined from digital photographs, and drainage was determined from soil pits.
