Vegetation structure in 26 forest patches (FP) and 4 reference sites within a continuous forest (CF) sampled in the fragmented Lacandon rainforest, Chiapas, Mexico.

The number of stems, dead trees, and logged trees are indicated, as well as basal area (BA, m2) and the evenness factor (EF) estimated for ten 50×2-m transects (0.1 ha) per site. Sites are arranged in order of increasing size (see site sizes in Table 1). EF represents the proportion of dominant species in the community.
