Excerpt from Reduction in Growth of Pole-Sized Ponderosa Pine Related to a Pandora Moth Outbreak in Central Oregon These analyses tested the hypotheses that tree basal area growth rates did not differ with species-area combinations or period. Assuming the effects of the drought, ongoing since the mid-1970s (cochran were the same in all three areas, a procedure was derived to isolate the effect of the pandora moth outbreak from the effect of drought on basal area increment of the sampled trees. Annual basal area increments of individual trees (al) for the four species-area combinations were adjusted to a common tree basal area at the start of each growing season to begin the procedure. These adjustments were made by per forming regression analyses (sas Institute 1988) for each year (1985 through 1994, i 1 through 10) by using the model.

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.
