Hardwood timber supplies in the United States
- USDA Forest Service, Southeastern Forest Experiment Station, Asheville, NC (US)
Long recognized for their wildlife, watershed, and nesthetic value, hardwoods are becoming increasingly important from the standpoint of timber production. The abundance of hardwood inventory volume, technological advances allowing greater substitution into softwood markets, and relatively low stumpage prices have generated a growing interest in increased utilization of the hardwood resource. The objective of this paper is to provide a broad overview of present and expected future hardwood timber supplies in the United States. In order to monitor the nation's forest resources and develop policies for their management, Congress has directed the Secretary of Agriculture through the Renewable Resources Planning Act of 1974 (RPA) to assess periodically the current and anticipated forest resources in the United States. Timber data presented in the 1989 Assessment were gathered from two main sources: the National Forest System and the regional Forest Inventory and Analysis (FIA) Work Units of the USDA Forest Service. The first half of this paper is devoted primarily to the current hardwood resource as it exists today. Since there are timing differences among the various surveys feeding into the RPA assessment, all current resource data were adjusted to common years: 1987 for area and inventory volume statistics and 1986 for growth, removals, and mortality. The second half of the paper describes past trends and future projections.
