Estimation of Height Growth Patterns and Site Index Curves for Japanese Red Cedar(Cryptomeria japonica D. Don) Stands planted in Southern Regions, Korea

Abstract

The purpose of this study is to estimate height growth patterns and site index curves (base index age 50 years) for Japanese red cedar trees(Cryptomeria japonica D. Don) grown in southern regions of Korea. The Chapman-Richards growth function was selected for stand height prediction using on the results of stern analysis data sets. Anamorphic base age invariant site index curves were presented based on this height prediction equation. The resulting site index prediction equation can provide an indication of the productivity of the site quality based on Japanese red cedar trees plantation ages planted in southern regions of Korea.
