Data Extent

Understory vegetation and site condition data from the "Nonnative Invasive Plants" study at the Penobscot Experimental Forest

This data publication contains understory plant density and cover class, substrate condition, microtopography, soil drainage, and canopy openness collected in 2006-2007 for 654 milacre plots (milplots) on 327 plots in 24 forest stands representing 10 silvicultural treatments (including an unharvested reference) and an old field on the Penobscot Experimental Forest (PEF) in central Maine, USA. These data were collected to obtain a more complete understanding of the extent of invasive species in a long-term PEF silvicultural experiment, as well as the relationships between treatment, site, and characteristics of the understory plant community.
