Geography comments: "on the southernmost bank of Ilha de Marchantaria... in the lower Solimőes River, approximately 15 km above its confluence with the Negro River"
altitude is for Ilha de Marchantaria and is from Parolin (2002, Rev. Biol. Trop.)
Habitat: tropical/subtropical moist broadleaf forest
Substrate: ground surface
WMT: 27.2
CMT: 26.3
MAP: 2000.0
Habitat comments: "seasonal várzea forest"
climate data are for the Ilha de Marchantaria and are from Parolin et al. (2002, Acta Amazonica)
MAP 1700 to 2300 mm
Life forms: trees
Sites: 1
Site area: 0.903
Sampling methods: belt transect
Sample size: 980
Years: 1982
Minimum size: 5.0cm dbh
Basal area: total is 40.6000
Sampling comments: counts are for a combined, adjacent 1882 x 4 m belt transect and 1500 m rectangular plot
text claims that the basal area "of the study area was 45m2 h-1" but figures in Table 2 add up to 40.60 m2 per 9028 m2, so that more precise figure is used instead
