The ORNL DAAC announces the release of dendrometry data from measurements made of trees in a tropical forest in Manuas, Brazil.
LBA-ECO CD-08 Tree Diameter Measurements, Jacaranda Plots, Manaus, Brazil: 1999-2001. Data set prepared by J.Q. Chambers, R.P. da Silva, E. Siza Tribuzy, J. dos Santos, and N. Higuchi. 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 which were stratified by plateau, slope, and baixio (lowland areas near small streams). Measurements were taken between June 1999 and December 2001.
LBA was an international research initiative under the leadership of Brazil. The project focused on the climatological, ecological, biogeochemical, and hydrological functions of Amazonia; the impact of land use change on these functions; and the interactions between Amazonia and the Earth system. The LBA-ECO component, which was funded by NASA, focused on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia? "
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data.
