Trembling aspen
Populus tremuloides Michx.

Distribution and Protected Areas – from Hamann 2005

Conservation Status Summary – from Chourmouzis et. al. 2009

“Protection levels for trembling aspen are very high across the province except in the CDF zone, where it is rare. Verification of this species in the CDF zone is recommended. Remnant populations threatened by urban development in the Fraser Valley should be considered for increased protection because pollination success may decline as the distance between female or male clonal clusters increases.”
