Abstract:

Forest managers in British Columbia increasingly manage some forests as mixed species stands that include paper birch (Betula papyrifera Marsh.), which regenerates naturally or can be planted. This genecology study, in association with ongoing tree improvement field studies, is aimed at developing seed transfer guidelines and identifying faster growing sources of paper birch for use in BC forests. Two of the objectives discussed here are to examine the effects of seed origin on (1) dormancy release (bud flushing), and (2) growth cessation and cold acclimation.
