The primary objective of the surveys is to periodically inventory and evaluate all forests and their related resources. These multiresource data help provide a basis for formulating forest policies and programs and for the orderly development and use of the resources. This report deals only with the extent and condition of forest land, associated timber volumes, and rates of timber growth, mortality, and removals. ACKNOWLEDGMENTS The Midsouth FL4 (MIDSO-FIA) unit gratefully acknowledges the cooperation and assistance provided by the Arkansas Forestry Commission, Georgia-Pacific Corporation, International Paper Company, Anthony Timberlands, and Weyerhaeuser in collecting field data. Appreciation is also expressed for the cooperation of other public agencies and private landowners in providing access to measurement plots. The following members of the MIDSO-FIA staff completed the field measurements:

The total land base for Louisiana is 28,493,700 acres. Of this, 14,611,000 acres are classified as agriculture, urban, residential, highways and other rights-of-way, and small wooded lots of strips too small

Data from the 1992 east Texas forest survey were used to derive fresh and dry biomass estimates for all trees, on timberland, greater than 1.0 inch in diameter at breast height (d.b.h.1. There are 382.2 million fresh tons in softwood species and 492.9 million fresh tons in hardwood species. The woody biomass resource averages 43.2 and 45.4 tons per acre for softwoods and hardwoods where they occur, respectively. Most of this biomass is in the stem portion of the trees-84 percent for softwoods and 74 percent for hardwoods. Nonindustrial private landowners hold 56 and 71 percent of the total softwood and hardwood biomass resource, respectively. OwnershipNonindustrial private owners have 566.0 million fresh tons of biomass (295.1 million dry tons) (appendix 4, fig. 4). This is 65 percent of the total forest resource. Forest industry holds 222.0 million fresh tons (115.3 million dry tons). The remaining 87.2 million fresh tons is in the public domain. Forest m eThe loblolly-shortleaf pine forest type has 336.3 million fresh tons of biomass (488.8 million dry tons), followed by 183.7, 172.8, and 165.9 million fresh tons in the oak-pine, oak-hickory, and bottomland hardwood types (94.4, 92.2, and 91.0 million dry tons), respectively. These three forest types collectively account for 98 percent of all fresh weight biomass (appendix 4, fig. 5). The remaining 2 percent of fresh biomass is in the longleaf-slash pine type. Diameter ClassA major portion of the State's biomass is in trees 2 7.0 and <17.0 inches in d.b.h. Trees in this diameter class account for 462.2 million fresh tons (239.4 million dry tons). These diameter classes account for 53 percent of the total biomass resource (appendix 4, fig. 6). Tree ClassThere are 665.9 million fresh tons (267.9 million dry tons) of biomass in growing-stock trees 25.0 inches in d.h.h. (appendix 4, fig. 7). Rough and rotten trees account for 104.4 million fresh tons (39.1 million dry tons) of biomass. Salvable dead trees account for only 3.2 million fresh tons, less than one-half of 1 percent of the total biomass resource. SpeciesThe predominant tree species in east Texas is loblolly pine, with 272.6 million fresh tons (135.4 million dry tons) of biomass. Shortleaf pine ranked second in dominance, with 84.7 million fresh tons (41.1 million dry tons), followed closely by sweetgum, with 80.6 million fresh tons (38.6 million dry tons). Together, these three species account for 50 percent of the State's fresh weight biomass.
