Growth responses of subalpine fir to climatic variability in the Pacific Northwest.

Presents the results of a study of regional variation in growth-limiting factors and responses to climatic variability in subalpine forests by analyzing growth patterns for 28 tree-ring growth chronologies from subalpine fir (Abies lasiocarpa (Hook.) Nutt.) stands in the Cascade and Olympic Mountains in Washington and Oregon. Introduction; Study areas; Methods; Chronology growth patterns; Climate-growth relationships; Conclusions.
