Book Description
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.
