Potential residual biomass in mature pine stands of the Midsouth, U.S.A.
The extent, location, and ownership of residual woody biomass available on mature pine timberland prior to the harvest of log-size pine was determined for the Midsouth States. Most of this residual is on non-industrial private timberland. Sweetgum (Liquidambar styraciflua L.) and loblolly pine (Pinus taeda L.) are the dominant species in the residual. Stems of all species < 25 cm in diameter comprise most of the residual (66%). A preharvest biomass operation may be the most efficient way to take advantage of these substantial levels of woody biomass.
