This book was released on 2015-06-26 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study gives an overview of the current inventory status and the projection of future forest inventories on other public timberland. Other public lands are lands administered by state, local, and federal government but excluding National Forest System lands. These projections were used as part of the 2005 USDA Forest Service Resource Planning Act timber assessment update. The projections were made by region and forest type by using the modified Aggregated Timberland Assessment System and the forest inventory data with methods and procedures consistent with the methods used for private and national forest inventory projections. Although the projected inventory volume differs by region, both softwood and hardwood inventories on other public timberlands in the United States are projected to increase over 60 percent during the next 50 years. Forest net growth exceeds harvest in most regions pushing inventory volumes up. The one exception is the Pacific Northwest East (ponderosa pine region) where the softwood inventory is expected to decrease until 2030 owing to lower softwood net growth and then slowly increase. The mature and old mature stands for both softwood and hardwood are projected to increase significantly for all regions especially in the South region where proportion of mature and old mature increases from 9 to 54 percent for softwood and 4 to 55 percent for hardwood.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Trim Timber Projections: An Evaluation Based on Forest Inventory Measurements Two consecutive timberland inventories collected from permanent plots in the natural pine type in North Carolina were used to evaluate the timber resource inventory model (trim). This study compares model predictions with field measurements and examines the effect of inventory data aggregation on the accuracy of projections. Pro jections were repeated for two geographic areas with two data aggregation schemes. The sensitivity of the model to harvest was tested with historical and adjusted values. For each simulation, the trim growth projection mechanism was tested with two types of yield tables. Yield tables developed from growth data produced projections that were closer to the measured inventory than did yield tables derived from volume data. This study suggests that timber growth measurements should be incorporated into trim yield tables when stands have the characteristics found in natural pine in North Carolina. The trim system is outlined, and the methods used to derive yield tables are discussed. Keywords: Yield-table projection, growth simulation, growth measurements, inventory data aggregation, inventory models, forest survey, regional timber supply studies, model validation, South.

Book excerpt: Excerpt from Spats: A Model for Projecting Softwood Timber Inventories in the Southern United States Simulating the development of regional forests is an essential component of long-term timber supply studies. The Southern Pine Age-class Timber Simulator (spats) was designed to be used in conjunction with a model of North American timber markets. The spats model can also be used as a stand-alone simulator of softwood forests in the Southern United States.
