This data set provides diameter at breast height (DBH) measurements made of trees in a dense terra-firme tropical moist forest at the ZF-2 Experimental Station, 90-km north of Manaus, Brazil. DBH was measured over two transects (East to West and North to South) which were established in 1996 by the Jacaranda Project (agreement between the National Institute for Research in the Amazon (INPA) and the Japan International Cooperation Agency, JICA). For each tree, a metal dendrometer band was fixed to the trunk and growth in circumference was measured monthly with digital calipers.
The transects measured 20-m x 2500-m, and were stratified by plateau, slope, and baixio (lowland areas near small streams). Topography location, distance along the transect, height at which the band was installed, local tree name, and field notes are also provided in the data files. Measurements were taken between June 1999 and December 2001.

Site description
This study was carried out in the ZF-2 Experimental Station of the National Institute for Research in the Amazon (INPA), approximately 90-km north of Manaus, the capital of Amazonas State, Brazil. The site is a dense terra-firme tropical moist forest, which dominates Central Amazon landscape (Higuchi et al., 1997). Two transect plots were established in 1996 by the Jacaranda Project. These transects measure 20-m x 2500-m (5 ha) each, oriented in East to West (E-W) and North to South (N-S) directions, and are stratified by plateau, slope and baixio (lowland areas associated with small streams). According to Ferraz et al. (1998), soil classification and textures for plateaus, slopes, and baixios are, respectively, Oxisols very clayey, Ultisols clayey sand and sandy clay, and Entisols very sandy. Within the two transects, soils present low fertility, high acidity, and high negative charges at depressions.
Dendrometer measurements
Initially, 300 individual trees were selected at random from the transect plots (Higuchi et al., 1998), equally distributed among topographical classes (plateau, slope and baixio), the E-W and N-S transects, and the diameter classes (between 10-cm and 30-cm DBH, between 30-cm and 50-cm DBH and greater than 50-cm DBH). Metal dendrometer bands were installed on each selected tree, which measured changes in stem diameter through return spring displacement. Because there is an adjustment period for the metal dendrometers the first readings should be discarded (Keeland and Sharitz, 1993), so only 12 measurements were used from 2000. The total number of tree measurements reported was 272, with the last measurement made December 2001.
Displacement measurements were taken by a digital caliper with precision of 0.01 mm. All metal dendrometers were installed in June 1999 when the first measurement was taken. Measurements were taken monthly between days 25 and 30.
