Table 14econd-growth white pine age-height data aA base-age invariant polymorphic site index equation was used to model the white pine (Pznus strobus L.) site-quality data provided by Frothingham (1914). These data are the accepted standard used by the Southern Forest Inventory and Analysis unit of the U.S. Department of Agriculture, Forest Service. An all possible growth intervals data structure was used, and autocorrelation parameters were incorporated into the site index model. It has recently been shown that these measures are necessary to obtain unbiased, efficient parameter estimates. The model is invertible, hence site index can be explicitly determined without the need for a numerical evaluation procedure. The site index model can be solved to provide an equation for any base age, hence it is applicable regardless of the choice of rotation age. Site index curves are graphed for base ages 25 and 50 years, and example calculations are provided.

Gen. Tech. Rep. RMRS-GTR-149. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Research Station. 17 p. http://www.fs.fed.us/research/infocenter.htmlThis assessment characterizes, at a regional scale, forest biomass that can potentially be removed to implement the fuel reduction and ecosystem restoration objectives of the National Fire Plan for the Western United States. The assessment area covers forests on both public and private ownerships in the region and describes all standing tree volume including stems, limbs, and tops. Analysis of treatment areas and potential removals is included. Additionally, the operational systems necessary to effect the treatments as well as potential erosion impacts, utilization opportunities and market implications were examined.
