Among the wood resources potentially available from forest areas are “other removals” which is a broad category that includes the unutilized wood volume from cut or otherwise killed growing stock, wood from cultural operations (e.g. pre-commercial thinning), or wood from timberland conversion to other uses (e.g., crop land, roads, and urban development but excluding timber volumes removed from the forest inventory due to reclassification of timberland to productive reserved forest land).
Other removals data is available online through the USDA Forest Service Timber Product Output database (http://www.fia.fs.fed.us). An estimated 1.66 billion ft3 (~ 24.7 million dry tons) of other removal wood resources were generated in 2007, with over 91% derived from private lands.
The USDA Forest Service projects that timberland acres will decline from 503.8 million acres in 1997 to 489 million acres in 2050, mostly as a result of urban development, with the greatest decline projected to be in the Northeast, the Southeast, and the Lake States due to increases in population and income.
