Summary Unclear whether this species occurs in Southeast Alaska. ARCTOS herbarium records are all of ''Populus balsamifera'' ssp. ''trichocarpa'' (''[[Populus trichocarpa]]'') and it seems plausible that this species is restricted to interior regions of BC into Yukon and Alaska - not reaching the coast before South Central Alaska.
