Establishment of Microstegium vimineum, an invasive exotic grass, in closed-canopy U.S. eastern forests was evaluated across a local (roadside to forest interior) and regional (across two geographic provinces) environmental gradient in West Virginia. The two geographic provinces were the Allegheny Plateau (more mesic) and the Ridge and Valley Province (more xeric). Biotic, abiotic, and disturbance variables were measured in (1) systematically located plots, starting from the roadside and extending 50 m into the forests, and (2) randomly selected, forest interior plots, with equal numbers of plots containing or not containing M. vimineum. Associations between the variables and the presence of M. vimineum at both scales were evaluated using generalized linear models.
