ABSTRACT

The objective of this study was to analyze the effects of thinning intensity on vertical distribution of crown fuel for wildfire in Pinus rigida stands. A total of 20 sample trees were harvested and used for development of a crown fuel vertical distribution model. The model developed in this study was used to analyze the crown fuel vertical distribution by thinning intensity. The results of this study showed that the coefficient of determination (  ) for the suggested vertical distribution model ranged from 0.961 to 0.981 and the estimated parameters were statistically significant (P <0.05). Canopy base height was 3.7m at the control site (non-thinning) while those of 20%-thinning and 40%-thinning intensity sites were 4.9m and 5.7m, respectively. The needles and twigs with less than 1cm diameter accounted for 0.22 kg/m³ of the canopy bulk density at the control site, but 0.18 kg/m³ in 20%-thinning intensity site and 0.16 kg/m³ in 40%-thinning intensity site.
