Title: Site Index Evaluations in a 100-Year-Old Eastern White Pine Plantation at the Biltmore Estate, NC
Author(s): McNab, W. Henry; Ritter, Brian A.
Date: 1999
Source: Paper presented at the Tenth Biennial Southern Silvicultural Research Conference, Shreveport. LA, February 16-18, 1999.
Description: The precision of these equations for estimating site index and the effects of four topographic variables on total height were evaluated in a 1.6-acre planted stand of 100-year-old eastern white pines (Pinus strobus L.) on the Biltmore Estate near Asheville, NC. A polymorphic site index equation developed for the Southern Appalachian Mountains was only slightly more precise than a polymorphic equation developed for New Hampshire and an anamorphic equation developed for Wisconsin. A regression model that induded age alone explained 72 percent of variation assodated with stand total height. The inclusion of four significant topographic variables increased the explained variation to 91 percent.
