abstract = "Forest biomass is an important variable for calculating carbon
stocks and greenhouse gas emissions from deforestation and forest
fires in Brazilian Amazonia. Its spatial distribution has caused
controversy due to disagreements over the application of different
calculation methodologies. Standardized networks of forest surveys
provide an alternative to solve this problem. This study models
the spatial distribution and original total stock of forest
biomass (Aboveground + Belowground + Fine and coarse litter) in
Brazil's state of Roraima, taking advantage of data from
georeferenced forest surveys in the region. Commercial volume
(bole volume) from surveys was expanded to total biomass. Kriging
techniques were used to model the spatial distribution of biomass
stocks and generate a benchmark map. All results were associated
with phytophysiognomic groups, climatic regions and land uses
(protected areas; agricultural use). We estimate forest in the
state of Roraima to have an original biomass stock of 6.32 × 109
Mg. Forest biomasses in areas with shorter dry seasons were higher
as compared to forests in regions with longer dry seasons. The
original vegetation in protected areas, independent of
phytophysiognomic group, has higher biomass compared to areas
currently under agricultural use. Protected areas support 65.8% of
Roraima's stock of forest biomass, indicating an important
potential role in REDD projects for conservation of forest carbon.
Information on spatial distribution of biomass stocks at a more
refined scale is needed to reduce uncertainties about the regional
character of carbon pools in Amazonia.",
