CARBON BUDGET OF UNITED STATES FORESTS
Q: How much carbon could
be sequestered if more trees were planted?
A: The amount of carbon sequestered
is a function of the area on which forest landowners could be convinced
to plant trees. Incentives include Federal cost-shares, forest management
assistance programs, and tax credits, and generally are targeted
at land which is marginal for agriculture. We projected carbon sequestered
under a scenarios which require a $110 million/year investment for
ten years. We adopted area estimates from a study by Moulton and
Richards (1990). They estimated how much area would be planted in
forests if $110 million/year were invested for ten years to provide
incentives for private landowners to plant trees. Funding was assumed
to be distributed across regions in a way to maximize carbon sequestration.
About an additional 2 MMT/yr. of C (Birdsey and Heath, 1995) could
be sequestered above the base scenarios over a fifty year period.
For more information about the scenario, see Haynes and others (1995).
