Critical land change information enhances the understanding of carbon balance in the United States Critical land change information enhances the understanding of carbon balance in the United States
Large-scale terrestrial carbon (C) estimating studies using methods such as atmospheric inversion, biogeochemical modeling, and field inventories have produced different results. The goal of this study was to integrate fine-scale processes including land use and land cover change into a large-scale ecosystem framework. We analyzed the terrestrial C budget of the conterminous United...

Estimating burn severity and carbon emissions from a megafire in boreal forests of China Estimating burn severity and carbon emissions from a megafire in boreal forests of China
Wildfires, especially those of large size, worsen air quality and alter the carbon cycle through combustion of large quantities of biomass and release of carbon into the atmosphere. The Black Dragon fire, which occurred in 1987 in the boreal forests of China is among the top five of such megafires ever recorded in the world. With over 30 years of accumulation of data and availability of...

Employing an ecosystem services framework to deliver decision ready science Employing an ecosystem services framework to deliver decision ready science
Public land managers have limited information to allow for the integration and balancing of multiple objectives in land management decisions including the social (cultural and health), economic (monetary and nonmonetary), and environmental aspects. In this article, we document an approach to consider the many facets of decision making by incorporating them into a decision context using...

Evaluating k-nearest neighbor (kNN) imputation models for species-level aboveground forest biomass mapping in northeast China Evaluating k-nearest neighbor (kNN) imputation models for species-level aboveground forest biomass mapping in northeast China
Quantifying spatially explicit or pixel-level aboveground forest biomass (AFB) across large regions is critical for measuring forest carbon sequestration capacity, assessing forest carbon balance, and revealing changes in the structure and function of forest ecosystems. When AFB is measured at the species level using widely available remote sensing data, regional changes in forest...

Carbon dioxide emissions and methane flux from forested wetland soils of the Great Dismal Swamp, USA Carbon dioxide emissions and methane flux from forested wetland soils of the Great Dismal Swamp, USA
The Great Dismal Swamp, a freshwater forested peatland, has accumulated massive amounts of soil carbon since the postglacial period. Logging and draining have severely altered the hydrology and forest composition, leading to drier soils, accelerated oxidation, and vulnerability to disturbance. The once dominant Atlantic white cedar, cypress, and pocosin forest types are now fragmented...

Executive summary. In Second State of the Carbon Cycle Report (SOCCR2): A Sustained Assessment Report Executive summary. In Second State of the Carbon Cycle Report (SOCCR2): A Sustained Assessment Report
Central to life on Earth, carbon is essential to the molecular makeup of all living things and plays a key role in regulating global climate. To understand carbon’s role in these processes, researchers measure and evaluate carbon stocks and fluxes. A stock is the quantity of carbon contained in a pool or reservoir in the Earth system (e.g., carbon in forest trees), and a flux is the...
