AL[S3] – State rank. Typically 21-100 occurrences, limited acreage, or miles of stream in the state.

Global rank: G3 – Imperiled globally because of rarity (6-20 occurrences, or few remaining acres, or miles of stream) or very vulnerable to extinction throughout its range because of other factors.
