Global Rarity Rank: G5T3T5
A Global Rarity Rank of G5T3T5 means: Vulnerable globally, or Secure -- Conservation status of the subspecies/variety is uncertain, and could range from moderate risk of extinction due to rarity or other factors, to uncommon, to common globally.

Did you know?
Alpine sweet grass, like its close relatives indian sweet grass (Anthoxanthum hirtum and A. nitens) and sweet vernal grass (A. odoratum) has a sweet fragrance when cut, which is a result of the presence of coumarine. This aromatic organic compound also produces the fragrance of fresh-cut hay, and is used in perfumes.

State Ranking Justification [-]
There are eight known extant populations and about half of these have fewer than 100 plants.
