10 cm were measured. Total height of largest DBH, tree closest to the center of the plot, diameter of crown along two perpendicular directions and the thickest closest tree in each plot were also measured. The litter samples were taken based on direct sampling in 0.5*0.5 m sample plots at the center and four corners of the plot. The results showed the total biomass in intact, protected, exploited and garden land uses were 450.12, 54.95, 12.85, and 5.38 tons per hectare, respectively. The amount of carbon stored in the land uses were 258.15, 35.52, 9.49 and 3.48 tons per hectare in in intact, protected, exploited and garden land uses, respectively. The results of Duncan test also showed there are significant differences in biomass and carbon storage among different land uses. ]]>

0.618) with actual damage (100% inventory). Adequate grid dimensions were determined 100 m × 100 m with plot areas of each 0.1 ha for plot sampling and 77.5 m × 77.5 m with sample line lengths of each 60 m for line sampling. Required time for line samplings were about 90% lower than plot samplings. These results indicate the line sampling can be used for accurate and rapid estimation of frequency of damaged trees due to selection cutting and ground skidding.]]>
