“…In the U.S., allometric equations developed from empirical data are used to calculate biomass in different forest components including growing stock, tops, branches, foliage, rough and rotten trees, small trees, standing dead trees, stump section, roots, and bark (Cost, 1990). The ratios of total forest biomass to the biomass in growing stock (for different regions and species groups) were calculated and used as the ratios of total tree volume to growing stock (Birdsey, 1992).…”

We developed a volume-to-biomass method based on age groups representative of forest development stages to estimate live tree biomass, C, and biomass and C accumulation rates of China's forests between 1973 and 1993. The data were from plot-level forest inventory, national-level inventory statistics, and ecological site studies specified to estimate biomass in different tree components. Our results indicate that carbon storage in China's forests was 4.34 Pg C in the early 1990s, an increase of 13% since the early 1970s. The annual forest C sequestration rate from the late 1980s to early 1990s was 0.068 Pg C/yr and approximately four-to five-times higher than in the 1970s and 1980s. The large C sink in China's forests in the early 1990s was likely related to age structure changes that had developed to more productive stages, a consequence of reforestation and afforestation programs from the 1960s. The results were compared with other C store estimates, which were based on the same inventory data. Various methods can produce estimates that differ in the direction of C flux as well as its magnitude. Separating age groups with the volume-biomass method could cause a 27% difference in estimated carbon pools but an 89% difference in C sequestration rates whereas the biomass density method would provide an estimate that differs by 65% in the C pools.

The relation between satellite measurements of the normalized difference vegetation index (NDVI), cumulated over the growing season, and inventory estimates of forest woody biomass carbon is estimated statistically with data from 167 provinces and states in six countries (Canada, Finland, Norway, Russia and the USA for a single time period and Sweden for two periods). Statistical tests indicate that the regression model can be used to represent the relation between forest biomass and NDVI across spatial, temporal and ecological scales for relatively long time scales. For the 1.42 billion ha of boreal and temperate forests in the Northern Hemisphere, the woody biomass carbon pools and sinks are estimated at a relatively high spatial resolution (8 Â 8 km). We estimate the carbon pool to be 61 F 20 gigatons ( 10 9 ) carbon (Gt C) during the late 1990s and the biomass sink to be 0.68 F 0.34 Gt C/year between the 1982 and 1999. The geographic detail of carbon sinks provided here can contribute to a potential monitoring program for greenhouse gas emission reduction commitments under the Kyoto Protocol. D

“…A subsequent conversion from bole carbon to whole-tree carbon was used to account for the contribution of roots, stumps, branches, tops, and cull trees. These ratios (Table l) were developed from Harmon ( 1993) and Cost (1990) based on allometric analyses and consideration of forest harvest practices. Lastly, sapling carbon (trees < 12.5 em diameter at breast height [dbh]) was included based on the biomass statistics in the study of Cost et al ( 1990).…”

The potential need for national‐level comparisons of greenhouse gas emissions, and the desirability of understanding terrestrial sources and sinks of carbon, has prompted interest in quantifying national forest carbon budgets. In this study, we link a forest inventory database, a set of stand‐level carbon budgets, and information on harvest levels in order to estimate the current pools and flux of carbon in forests of the conterminous United States. The forest inventory specifies the region, forest type, age class, productivity class, management intensity, and ownership of all timberland. The stand‐level carbon budgets are based on growth and yield tables, in combination with additional information on carbon in soils, the forest floor, woody debris, and the understory. Total carbon in forests of the conterminous U.S. is estimated at 36.7 Pg, with half of that in the soil compartment. Tree carbon represents 33% of the total, followed by woody debris (10%), the forest floor (6%), and the understory (1%). The carbon uptake associated with net annual growth is 331 Tg, however, much of that is balanced by harvest‐related mortality (266 Tg) and decomposition of woody debris. The forest land base at the national level is accumulating 79 Tg/yr, with the largest carbon gain in the Northeast region. The similarity in the magnitude of the biologically driven flux and the harvest‐related flux indicates the importance of employing an age‐class‐based inventory, and of including effects associated with forest harvest and harvest residue, when modeling national carbon budgets in the temperate zone.
