Dataset Abstract:

Surface root biomass, rainfall exclusion experiment, Tapajos National Forest (LBA):
This data set contains biomass estimates for coarse roots visible at the soil surface. All surface roots intersected along three 1000m long x 1m wide transects were measured, and in most cases identified by species. We assumed an average wood density of 0.7 g cm-3 for making biomass conversions. These data come from a rainfall exclusion experiment being implemented in the Tapajos National Forest, Santarem, PA, Brazil. Two one hectare plots have been established to monitor the effects of water stress on the forest. Following a one year intercalibration period plastic panels were installed in the understory of the treatment to exclude rainfall during the rainy season. These data were collected in August of 1999, prior to panel installation.
