Summary:

This dataset is a census of approximately 21,000 trees sampled at the Tapajos National Forest (south of Santarem, Para, Brazil) over a three month period in 1997 by the Fundacao Floresta Tropical (FFT). Approximately 400 hectares were surveyed in total in four different areas. Each area was approximately 100 ha and each area had roughly 5,000 trees. Tree DBH, genus and species, commercial height, commercial volume, and the relative location of the tree in x,y plane were measured.

Trees were sampled in 1997 before the areas were logged.
