Landfire -C: a tool for estimating land carbon stocks and change

This tool provides an overview of Landfire-C, a geospatial and tabular data integration product for estimating land carbon stocks and change. It includes information on the methodology, workflow, and data sources used. The tool also provides insights into the stock change attribution and estimated harvested volume for harvested wood products (HWP) in California from 2010 to 2012.
