[4] Biogeography indicates that the coastal populations were probably isolated during an epoch of glaciation of the Rocky Mountains range, but this is also not very helpful in resolving the remaining problems of within-group diversity, and inter-group relationships. In the Columbia Plateau ecoregion, it is an Oregon Conservation Strategy Species. It is widespread throughout the extensive shrub-steppe of central and eastern Oregon.
