Book Description
Research interest in the forests of Oregon and Washington east of the Cascade Range can be traced back to 1897, when Fredrick V. Coville of the Division of Forestry, U.S. Department of Agriculture, reconnoitered the Cascade Range Forest Reserve to report on forest growth and sheep grazing there in an 1898 report. Subsequent forest survey in the late 1890s and early 1900s was stimulated by anticipation of the timber boom that would follow arrival of a railroad. In 1908, Gifford Pinchot's new Forest Service sent young Thornton Taft Munger to study the encroachment of lodgepole pine (Pinus contorta Dougl. ex Loud.) on the more valuable ponderosa pine (Pinus ponderosa Dougl. ex Laws.) stands. By the end of the year, Munger was in charge of the North Pacific District's one-man Section of Silvics, which evolved to become the Pacific Northwest Forest Experiment Station in 1924 with him at the helm. The forest research effort east of the Cascade Range picked up speed with establishment in 1931 of the Pringle Falls Experimental Forest to research the ecologically and economically viable silvicultural systems that would convert the stagnant old-growth forests into more-productive secondgrowth forests. During the ensuing six and one-half decades, a small group of Forest Service researchers and their university counterparts working at the experimental forest and, beginning in 1963, the Bend Silviculture Laboratory, pioneered and pursued the practical silvicultural research that both led and responded to the evolution of their science.

Book Description
The silviculture of mixed conifer forests in eastern Oregon and Washington is described. Topics discussed include ecological setting, damaging agents, silviculture, and management. The relevant literature is presented, along with unpublished research, experience, and observations. Research needs are also proposed.

Book Description
Advance regeneration is common under decadent, old-growth stands of California red fir (Abies magnifica A. Murr.). Intense competition for the site's resources can create sapling stands of poor vigor and advanced age. When competition is reduced by overstory removal and thinning, suppressed advance regeneration has been shown to respond with increased growth. But, to select leave trees, land managers need to know which tree characteristics we associated with growth after release and thinning. This paper reports those easily measured tree characteristics found to be most closely associated with growth after 8 years, on the Swain Mountain Experimental Forest in northeastern California.
