Environment
Habitat: tropical/subtropical moist broadleaf forest
Substrate: ground surface
Disturbance: selective logging
MAT: 21.8
WMT: 22.6

The sample plots, 122 m. (400 ft.) square (= 1418 ha. = 3673 acres), were marked out by chain and compass. Each was divided into four strips 122 x 30.5 m. (400 x 100 ft.), and all trees over 10 cm. (4 in.) d.b.h. were measured (p. 39)
