The identity of similar birches in Alaska is disputed; some include them in B. occidentalis, while others regard them as hybrids between Betula neoalaskana and Betula glandulosa.[1] A 2023 study sequenced chloroplast genomes of species from the genus Betula for phylogenetic analysis. Of the Betula species, B. occidentalis was most closely related to B. pendula purple rain and B. platyphylla.[5]
The foliage is browsed by sheep, goats,[6] and birds; some small birds also consume the seeds.[2]
Some Plateau Indian tribes used water birch to treat pimples and sores.[7]
It is also a riverside tree found in western USA that reacts to water stress by becoming isohydric.[8]
