Carbon and nitrogen status by decay class in fallen dead wood of three pine species in southern Korea

The importance of a quantitative assessment C and N contents dead wood is increasing in forest ecosystems. This study aimed to determine the density carbon (C) nitrogen (N) status with decay class for three pine species (Pinus densiflora, Pinus rigida, koraiensis) southern Korea. concentration was significantly different among (P. 50.31%; P. koraiensis, 47.22%; 44.96%), whereas did not affect (p > 0.05). content all decreased class. concentrations increased more rapidly rigida koraiensis than an Thus, unchanged or that densiflora because reduction Our results indicate unchanged, increased, depends on
