Fig. 1

Compositions of ground cover in a managed pine rockland preserve in South Florida measured prior to the first prescribed burn (T0), 1 week post-burn (T1), 4 weeks (T4), and 14 weeks later (T14). The position of points in each ternary diagram illustrates the percent of ground surface within a quadrat covered by bare ground (soil), dead plant material (litter), and live plants (vegetation). Color depth of points separately indicates the percent of vegetation cover consisting of shrubs or trees. Ellipses within diagrams are produced from means and variances of compositions within quadrats
