Survey to Evaluate Escape of Eucalyptus spp. Seedlings from Plantations in Southeastern USA

Table 3

Results of logistic regression analysis of continuous (latitude, canopy cover, and percent bare ground), and binary (wetland, Eucalyptus planted previous or present) variables from the sampling survey. Canopy cover and percent bare ground data for one South Carolina site were not collected and so this site was excluded from the analysis.
