Abstract: Inventory Program measured in 2007 were used to analyze annual diameter growth characteristics for
major tree species distributed in Chungnam province. A total of 717 sample trees from 49 plots distributed in Chungnam province were measured and analyzed for annual diameter growth characteristics. As stand age and stand density increased. annual diameter growth rates for major species tended to decrease. The species of Prunus sargentiJ{2.14mm/yr) showed the best annual diameter growth rates and the others are Quercus sen·ata(2.10mm/yr), Pinus thunbergil.2.03mm/yr), Pinus densiflors<.1.91m/yr), and Castanea crenata(l.90mm/yr) in order. This information could be very useful to understand annual diameter growth characteristics for major species distributed in Chungnam province.
