Seedlings from 29 seed lots of western white pine (Pinusmonticola Dougl. ex D. Don) from the British Columbia coast and interior ranges were tested for frost hardiness. Detached needles were exposed to a series of freezing temperatures, and relative hardiness was calculated based on visual scoring of injury. Seasonal progress in hardening was tested in seedlings maintained at the University of British Columbia (coastal) nursery. In addition, the same seed lots grown at a coastal and an interior field plantation were tested once during the hardening process. There was a significant (p = 0.04) r

High Zr/Nb and Zr/Y ratios and lack of strong -ve Eu anomalies suggest that the felsic component of the provenance was dominantly made up of tonalites-trondhjemites; granites and granodiorites were very subordinate constituents.

The most basic guidelines for germplasm movement involve the use of Regions of Provenance (RoP).
