System: Terrestrial
SubSystem: Barrens And Woodlands

State Protection: Not Listed
Federal Protection: Not Listed

State Rarity Rank: S3
A State Rarity Rank of S3 means: Typically 21 to 100 occurrences, limited acreage, or miles of stream in New York State.

Global Rarity Rank: G4?
A Global Rarity Rank of G4? means: Apparently Secure globally (most likely) - Conservation status is uncertain, but most likely uncommon 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. More information is needed to assign a firm conservation status.

Did you know?
What is talus? Talus, or scree, is a steep, rocky slope usually found at the base of a mountain. The block size of the talus is strongly influenced by the type of rock forming the cliff face and rate of erosion. Shale or rapidly eroding sandstone forms unstable small loose talus as it is eroded from the mountain's face. The unstable nature of shale results in uneven slopes and many small rock crevices. Other bedrock, such as hard dolostone caprock, produces stable, very large talus that provides habitat for larger organisms.

State Ranking Justification [-]
There are several hundred occurrences statewide. A few documented occurrences have good viability and some are protected on public land or private conservation land. This community is limited to areas with acidic talus across the state, and includes several large, high quality examples. The current trend of this community is probably stable for occurrences on public land, or declining slightly elsewhere due to moderate threats related to development pressure.
