Rank Reasons
Known from only 8 occurrences, all in Clearwater County, Idaho. All sites have lost habitat due to development (transportation, industrial, and residential) associated with timber harvest. Numerous active and abandoned roads and old logging railroad grades traverse the riparian communities supporting Phlox idahonis.
Ecology & Habitat

Habitat

Occurs in 3 types of habitats, the most common being open meadows dominiated by grasses, but rich in forbs, and surrounded by western redcedar (Thuja plicata) forests. Also in shrub communities dominated by thin-leaf alder (Alnus incana) or alder buckthorn (Rhamnus alnifolia), and (rarely) in coniferous forests.
