Table 1: Summary of repeated measures ANOVA models on nonnative prevalence across multiple riparian buffer widths in Delaware and Pennsylvania, 2007-2008. We tested for within-sample effect of distance from buffer edge as well as the interaction between distance and total riparian buffer width, basal density at sampled distance, and canopy coverage at sampled distance. Stars indicate significance ( ). We further tested for trends across buffer width exhibiting significant ( ) linear, quadratic, or cubic relationships.
