Conteúdo: | As in many other developing countries, the state government of Acre, Brazil, is developing a program for compensating forest holders (such as communities of rubber tappers and indigenous peoples as well as small, medium and large private land holders) reducing their emission of atmospheric heat-trapping gases by not deforesting. We describe and then apply to Acre a method for estimating carbon stocks by land cover type. We then compare the results of our simple method, which is based on vegetation mapping and ground-based samples, with other more technically demanding methods based on remote sensing. We estimated total biomass carbon stocks by multiplying the measured above-ground biomass of trees >10 cm DBH in each of 18 forest types and published estimates for non-forest areas, as determined by measurement of 44 plots throughout the state (ranging from 1 to 10 ha each), by land-cover area estimated using a geographical information system. State-wide, we estimated average above-ground biomass in forested areas to be 246 ± 90 Mg ha1; dense forest showed highest (322 ± 20 Mg ha1) and oligotrophic dwarf forest (campinarana) the lowest biomass (20 ± 30 Mg ha1). The two most widespread forest types in Acre, open canopy forests dominated by either palms and bamboo (for which groundbased data are scant), support an estimated 246 ± 44 and 224 ± 50 Mg ha1 of above-ground biomass, respectively. We calculate the total above-ground biomass of the 163,000 km2 State of Acre to be 3.6 ± 0.8 Pg (non-forest biomass included). This estimate is very similar to two others generated using much more technologically demanding methods, but all three methods, regardless of sophistication, suffer from lack of field data.
