Uses by native peoples
(Ethnobotany database)
Abies hosts caterpillars of 55 species
of butterflies and moths, in some areas.
Saplings can be killed, and growth and regeneration of this plant can be severely limited, by large populations of
western moose Alces alces andersoni,
who will eat buds and branches in ❄ winter, when their preferred food (forbs, ♒︎ aquatics, and willow and birch shoots) is unavailable.
Unless moose populations are kept in check by predators.
