Abstract
In this paper we examine the influence of precipitation and temperature deviations on regional volume growth rates in even aged, onnen.,ed second growth Douglas fir (
Pseudotsuga menziesii [Mirb.] Franco) stands. Between 1969 and 1986, average volume growth rates in natural stands of coast Douglas fix in western Washington and Oregon were negatively correlated with high summer temperatures and positively correlated with higher temperatures during the non growing season. Results support the hypothesis that cool wet summers and mild winters contribute to high productivity of conifers in the Pacific Northwest.
