dc.description.abstractThe purpose of this study was to investigate the dendrochronological and dendroclimatological potential of yellow-cedar in the Pacific Northwest of North America. A primary objective was to establish whether the growth response of yellow­ cedar is sensitive to climate fluctuations. Once it was determined that yellow-cedar was inherently sensitive, further dendroclimatological investigations were attempted. Trees were sampled at five sites between latitudes 50° and 51° on Vancouver Island. A total of 380 increment cores were collected in the summer of 1994. The samples were subsequently visually cross-dated, prior to ring-width measurement. Site indices were created and the five sites revealed a strong visual and statistical similarity. A regional index was constructed that represents the oldest living chronology for tree growth in Canada. A response function analysis was initiated to determine the significant climatic parameters to ring growth. This analysis identified previous August temperature as the variable most likely to influence variation in ring width. This variable was used to estimate current August temperature and associated parameters. The chronologies were compared to other relevant research on Vancouver Island and a common climate signal was apparent.
