Forest resources of Louisiana, 1991

Abstract

The findings of the sixth Louisiana forest survey are summarized in this report. The survey is administered by the U.S. Department of Agriculture, Forest Service, Southern Forest Experiment Station, headquartered in New Orleans, Louisiana. The Forest Inventory and Analysis (SO-FIA) work unit located in Starkville, Mississippi, is responsible for conducting the surveys. The following seven Midsouth States are under the administration of the Southern Forest Experiment Station (listed in the order the surveys are conducted): Alabama, Louisiana, Texas, Oklahoma, Mississippi, Arkansas, and Tennessee. Louisiana is subdivided into five forest survey units (fig. 1): North Delta (Unit 1), South Delta (Unit 2), Southwest (Unit 3), Southeast (Unit 4), and Northwest (Unit 5). These divisions facilitate field work and data analysis because the unit boundaries are correlated fairly closely with the physiographic and vegetative regions of the State. Tables and figures present data for January 1,1991, as well as estimates of trends. Comparisons, unless otherwise noted, are made between estimates for January 1, 1984, and January 1, 1991. The appendix describes survey methods and data reliability, defines terms, lists common tree species, and provides 22 standard tables.
