Sentence examples for annual sequestration from inspiring English sources

Assuming that only one fifth of the area is comprised of young trees (based on Forest Service planting figuresviii ), annual sequestration is estimated as being 30,000 t C yr-1.
Emissions from deforestation and forest degradation are obvious, but current forests can also be unstable and turn into sources, e.g. when affected by calamities, potential saturation effects (e.g. ageing forests with smaller annual sequestration rates than before), and a rather slow responding ability.
Figure 2 presents the annual sequestration rates by forest management (FM) in Gg CO2eq./a, where the IEEAF data are combined with the data for the respective WEHAM scenarios.

Recent attention has focused on the high rates of annual carbon sequestration in vegetated coastal ecosystems marshes, mangroves, and seagrasses that may be lost with habitat destruction.
Estimates of net annual carbon sequestration in agroforestry crops (Table 3) indicate that components with the highest rates in India are poplar, eucalypt, and bamboo (species in the Bambusae tribe).
