Large, old western redcedar trees provide a wide range of ecological functions and are an integral part of coastal First Nations’ culture in British Columbia. Redcedar bark is commonly removed from tree trunks and used in baskets, hats and clothing. The surviving tree forms a permanent scar that can be crossdated to determine the year of past cultural modifications. We have developed multi-century chronologies for western redcedar and used them to crossdate scars on culturally modified trees and stumps of trees cut before European settlement. We have dated up to 4 or 5 modifications on a single tree, dating back to the year 1541 AD. We demonstrate how we include our research results in "CSI: Cedar Science Investigations", tree-ring workshops presented to school children and youth groups in British Columbia.
