Western redcedar
Thuja plicata Donn ex D. Don

Distribution and Protected Areas – from Hamann et.al. 2005

Conservation Status Summary – from Krakowski et. al. 2009

“Western redcedar is adequately protected in core ex situ and in situ locations, although additional seed collections from peripheral populations in the Interior would provide a more comprehensive set of baseline samples. Seed for this species must be periodically replaced due to deteriorating viability in long-term storage. Inter situ representation in primary trials is only marginal for the Maritime low SPU, and completely absent for the other coastal SPUs. Administratively, genetic resource management for this species would be greatly enhanced by developing interior SPUs, where the effects of climate change are expected to be considerable. Results from provenance and genecological studies should be utilized to delineate appropriate units.”
