Book excerpt: Excerpt from Twenty-Year Growth of Ponderosa Pine Saplings Thinned to Five Spacings in Central Oregon Stand density and understory vegeta tion have had significant effects on height growth throughout 20 years of observation following thinning. Under story vegetation has had the greatest effect on height growth at the wider spacings, reducing growth from 15 to 50 percent during some periods. Twenty years after thinning, low density plots contain less woo'd fiber than high density plots. On the other hand, widely spaced trees are much larger than narrowly spaced trees and collectively are now producing almost as much wood volume annually as high density plots. Even though most of the trees left after thinning were 70 years old, stagnated, and suppressed by overstory, they have responded well to overstory removal and release, and trees at the three widest spacings appear capable of producing a usable crop of timber despite their advanced age.

Book excerpt: Excerpt from A Ponderosa Pine-Lodgepole Pine Spacing Study in Central Oregon: Results After 20 Years Twenty years after planting, the net volume yield of pure ponderosa pine and pure lodgepole pine at the five spacings reflect the pattern of growth during this time - less wood produced by ponderosa pine at the 6 9 and 12-foot spacings and more wood produced at the 15 and 18-foot spacings when compared to lodgepole pine.

This book was released on 1991 with total page 808 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COWFISH model, developed and applied in selected Montana streams, was tested on 14 streams in Idaho, Nevada, and Utah, where it proved to have little value for predicting numbers of trout in watersheds grazed by livestock. The model holds promise for estimating the health of stream channels and riparian complexes.
