State Rarity Rank: S2S3
A State Rarity Rank of S2S3 means: Imperiled or Vulnerable in New York - Very vulnerable to disappearing from New York, or vulnerable to becoming imperiled in New York, due to rarity or other factors; typically 6 to 80 populations or locations in New York, few individuals, restricted range, few remaining acres (or miles of stream), and/or recent and widespread declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G4G5
A Global Rarity Rank of G4G5 means: Apparently or Demonstrably Secure globally - Uncommon to common in the world, but not rare; usually widespread, but may be rare in some parts of its range; possibly some cause for long-term concern due to declines or other factors.

State Ranking Justification [-]
There are 15 known locations for this moss in the state. Thirteen older specimens were verified as part of the update to the rare moss list of New York (Cleavitt et al. 2006). Several new sites were identified as a part of that project in Dutchess, Ulster and Warren Counties. In 2009, a few new sites were located in the southwestern Catskills. Easily overlooked and similar to other species, further surveys should turn up more locations for this moss.
