Douglas fir and limber pine tree rings were collected from lower forest border sites across central Idaho. Sub-annual tree-ring chronologies were used to independently reconstruct seasonal precipitation over the past six centuries. Singular spectrum analysis indicates that annual and summer through winter precipitation exhibits significant decadal and multidecadal variability, whereas spring precipitation shows energetic behavior only at interdecadal timescales.
