Thinning: Douglas-fir responds well to thinning at an early age or until the trees reach pole and small sawlog size. The method of thinning becomes more important in the sawlog stands. For the thinning response to be good and the danger from tipover and breakage low, care should be taken to leave the stand in a thrifty condition. During most.

Understanding Douglas Fir's Strengths & Weaknesses. Throughout the learning curve that J. Gibson McIlvain has gone through in our decade-long relationship with carrying softwoods, we’ve come to understand the up sides and down sides of using Douglas Fir. Douglas Fir, a distinctive North American tree growing in all states from the Rocky Mountains to the Pacific Ocean, is probably used for more lumber and lumber product purposes than any other individual species grown on the American Continent. The total Douglas Fir sawtimber stand in the Western Woods Region is estimated at billion board feet.

Commercial Thinning of Douglas-Fir in the Paciic Northwest by Norman P. Worthington and George R. Staebler* Paciic Northwest Forest and Range Experiment Station INTRODUCTION Thinning is probably the major silvicultural practice characterizing intensive.
old Douglas fir with 10 per cent hemlock, cedar, balsam fir, and maple. The present second-growth stand originated from natural reproduction after clear felling of the virgin timber inand the stand has been allowed to grow in its natural state until this first thinning took place.
Effects of variable-density thinning on understory diversity and heterogeneity in young Douglas-fir forests / Summary Nine years after variable-density thinning (VDT) on the Forest Ecosystem Study, we examined low understory vegetation in 60 plots of eight stands (four pairs of VDT and control).
Precommercial thinning is a practi-cal means of substantially increasing the production of usable wood. The larger the trees must be to be merchantable, the greater are the gains from precommercial thinning. This paper provides guidance on when and how to precommercially thin stands of nearly pure Douglas-fir.
Relative gains. Pseudotsuga menziesii is an evergreen conifer species in the pine family, cateringwhidbey.com is native to western North America and is known as Douglas fir, Douglas-fir, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (P. menziesii var. menziesii), Rocky Mountain Douglas-fir (P.
menziesii var. glauca) and Mexican Douglas fir (P. menziesii var. lindleyana).Family: Pinaceae. Overstory Response to Alternative Thinning Treatments in Young Douglas-fir Forests of Western Oregon Abstract An increase in land dominated by young second-growth Douglas-fir forests in the Pacific Northwest has coincided with heightened concerns over loss of old-growth habitat.
Jan 28, · Aim of this study was to determine the long-term effects of thinning regime with different intensities on the stand and tree social classes development, particularly regarding the old question of compensative effect between stocking and girth improvement using the example of Douglas-fir.

Adjusting rotation or commercial thinning can compensate for lack of early stand management or heavy early thinning. earlier reports have summarized the results to (Bell and Berg ) and (Berg and Bell ). These studies, designed only to test the response of young Douglas-fir to intensive, frequent thinnings, have provided good.
Douglas fir needles give a strong citrus fragrance. Position in Irish Forestry Douglas fir was first introduced to Ireland in and was initially planted on old woodland sites. While excellent state plantations of Douglas fir were harvested in County Wicklow, along.
maximize when thinning is an option because of the variable growth responses to thinning intensities and intervals, the potential for capturing mortality, and the large number of potential thinning regimes that must be tested.
When stand growth models are used to estimate mortality and response to thinning, computers can quick-Cited by: 7. noted that selective thinning caused greater residual stand damage than a herringbone thinning. In a commercial thinning using a small helicopter with a payload capacity of 1, kg (2, pounds), Flatten () found that damage to a young Douglas-fir stand appeared to be far less than typically found with sky-line systems.
