Growth of radiata pine pinus radiata under the direct sawlog regime



Growth of radiata pine pinus radiata under the direct sawlog regime



New Zealand Journal of Forestry 25(1): 15-34



To analyze the growth of radiata pine (P. radiata D. Don) managed under the direct sawlog regime, plots were sought which had been thinned to a final stocking of about 200 stems/ha near the time of high pruning. Data were available for 43 plots at 23 locations throughout New Zealand, including 22 plots at 10 different trials in the Rotorua region. Growth trends differed between regions, indicating the need for growth models (when based on top height) to be prepared regionally. Estimates based on the extrapolation of straight-line regressions for each Rotorua-region trial predict a basal area of 39-46 m2/ha at top height 36 m. Extrapolation of an overall linear regression for the 9, planted, butt-log-pruned, Rotorua plots resulted in an estimate of 44 m2/ha basal area at top height 36 m. A similar estimate based on the 6 regenerated plots gave about 41 m2/ha. Estimates for planted, butt-log-pruned plots at Mangatu, Gwavas and Santoft forests were 56-64 m2/ha at top height 36 m. Estimates for Mohaka, Te Wera, Golden Downs and Otago Coast forests (based on limited data) lie within or beneath the estimated range for the Rotorua region. Results indicate that the Beekhuis yield-prediction method is inappropriate for stands in the Rotorua region which have been thinned early and heavily; for these the Kaingaroa Growth Model gives a better estimate. Data from Mangatu, Gwavas, Santoft and Ngaumu forests suggest that the Beekhuis method may be suitable for the direct sawlog regime on at least these forests.
