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

Figure 1

Schematic diagram of sampling design. Transects were 90 m in length, containing 30 cells 3 × 3 m. The first cell was randomly selected from the five cells inside the stand boundary, and then cells were systematically sampled every 15 m throughout the length of the transect. For example, in the 4 transects shown in the figure, only blue cells would be sampled for seedlings and environmental variables. Transects were oriented perpendicular to the boundary edge and evenly spaced around the entire Eucalyptus stand.
