Wood density (DM) is an important variable for estimates of tree or arboreal-shrub carbon stocks in terrestrial ecosystems. Calculated from sample disks using the sapwood shell and core of the disks using the dry weight as a function of the saturated volume of the part. This subject is little investigated in forests and even less in open areas of the Amazon biome as savannah and grassland areas of the Brazilian Amazon. The largest block of Brazilian Amazonian savannas is in Roraima. This study investigated the variation of the basic wood density of common shrubs in the Roraima tillage, near the city of Boa Vista--RR. The DM variations of 8 common species in the area around Boa Vista were verified in transects following the traditional routes of the Lavrado. The non--destructive method was used to obtain wood pieces from the shrub canopy with diameters between 5 and 10cm, following recommendations from …
