Abstract

The purpose of this study was to analyze annual tree ring growth characteristics for major tree species distributed in Chungbuk province. A total of 800 sample trees from 56 permanent sampling plots measured by the 5th Korean National Forest Inventory Program in 2007 was used for the calculation of annual growth rates. According to the results of this study. the species of Robinia pseudoacacia{2.30mm/yr) showed the best annual tree ring growth rates and the others are Quercus serrata(2.27mm/yr)Prunus sargentii(1.98mm/yr) and Lanrix leptolepis(1.98mm/yr) in order. Most of the major tree species in Chungbuk province, as tree age and stand density increased, annual tree
ring growth rates tended to decreased. This information could be very useful for forest managers to understand annual tree ring growth characteristics in Chungbuk province.

Key words - Annual tree ring growth. Radial growth, Chungbuk province
