Geography comments: "on the southernmost bank of Ilha de Marchantaria... in the lower Solimões 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.)

Environment
Habitat: tropical/subtropical moist broadleaf forest

Substrate: ground surface

WMT: 27.2

CMT: 26.3

MAP: 2000.0

Habitat comments: "seasonal vârzea forest"
climate data are for the Ilha de Marchantaria and are from Parolin et al. (2002, Acta Amazonica)
MAP 1700 to 2300 mm

Methods
Life forms: trees

Sites: 1

Site area: 0.903

Sampling methods: belt transect

Sample size: 980 individuals

Years: 1982

Size min: 5

Basal area: 40.6

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
