Geography comments: "The altitude ranges between 400 and 472 m"
Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Substrate: ground surface
MAT: 19.0
MAP: 1800.0
Habitat comments: "The climate is L PU perhumid subtropical... The forest remnant comprehends 230 ha of primary-like forest and near 70 ha of areas in secondary succession and marshes... It is considered here primary-like forest as a forest without known perturbations in the last thirty years, according to local informants. Previously, the area was disturbed due to timber harvest"
MAT and MAP are for Chiapetta and are from Coelho et al. (2011)
Life forms: trees
Sites: 127
Site area: 0.966
Sampling methods: no design
Sample size: 483
Minimum size: 5.0cm dbh
Basal area: 26.7200 per ha
Sampling comments: "The phytosociological investigation was carried out through the point quarter method (Cottam & Curtis 1956). The 127 sample units were marked 20 m apart in two parallel lines"
"The density of trees with DBH ≥ 5.0 cm was 524.7 ha-1" so the effective site area is 502/524.7 = 0.9657 ha
