Abstract:

Results are reported from a provenance study of incense-cedar (Calocedrus decurrens), a tree species native to forested regions of Oregon, California, and Baja California. Seedlings from six geographically distinct regions were measured over a 12 yr period in a common-garden study located near the center of the species' native range. In general, among-region genetic variation was small. However, differences in height, stem volume, and crown form between trees from the southernmost region sampled and trees from the other five study regions were large and significant. Further studies of within-population genetic variation are recommended prior to initiating any tree improvement activities. West. J. Appl. For. 9(4):113-117.
