Thinning to a CSI target level allows priorty to be placed on spacing over tree frequency; whereas thinning to a basal area, trees/acre, SDI, Rd or CCF target level emphasizes tree frequency alone.

Get this from a library. Dominant Douglas-fir respond to fertilizing and thinning in southwest Oregon. [Richard E Miller; Pacific Northwest Forest and Range Experiment Station (Portland, Or.)]. Traveling across the state, you soon discover that Oregon is home to a wide range of trees.

There are 30 native coniferous species and 37 native species of broadleaf trees. Oregon varies greatly in terms of elevation, temperature, wind, rainfall and soil composition. Combinations of all these factors help determine the dominant tree species of an area.

This publication is part of the Alternative Forest Management series. It describes a case study on thinning in the mature Douglas-fir stands common to interior southwestern Oregon, many of which have become very dense and are at risk of loss due to wildfire, drought, and insect attack.

Following a wide thinning from below, nearly all the trees in the study responded with. Oregon and Gabriel F.

Thinning is removing selected trees from a stand to allow others to continue growing. Ordinarily, a woodland manager uses a thinning system that encourages the remaining trees to grow in a manner consistent with the manager’s objectives for those : William H.

Much is known about the effects of thinning on stand characteristics such as volume growth and rates of overstory tree mortality, as well as on individual tree characteristics such as diameter growth and live crown ratio (Smith, ).Several long-term studies have related tree and stand development to such measures of stand density as basal area, stand density index (Reineke Cited by: C.

Burton 3 and Erich Kyle Dodson 1 1 Department of Ecosystems and Society, Oregon State. Large-scale commercial thinning of young forests in the Pacific Northwest is currently promoted on public lands to accelerate the development of late-seral forest structure for the benefit of wildlife species such as northern spotted owls (Strix occidentalis caurina) and their prey, including the northern flying squirrel (Glaucomys sabrinus).

To demonstrate the trade-off between physical volume, economic return, and stand diameter, examples of thinning regimes for maximizing volume, forest rent, and soil expectation are compared with an example of maximizing volume without by: 7.
