    Description

    The FIA program does not directly measure forest C stocks. Instead, a combination of empirically derived C estimates (e.g., standing live and dead trees) and models (e.g., understory C stocks related to stand age and forest type) are used to estimate forest C stocks. A series of recent refinements in FIA estimation procedures have sought to reduce the uncertainty associated with the national C inventory by: 1) refining forest floor C estimates with in situ data, 2) updating the live belowground and understory C pools modeling approaches, 3) refining objective delineations between woodland and forest land uses, and 4) revising managed land delineations. The results of these studies in the context of forest C accounting and future refinements are discussed in the context of UNFCCC reporting.
