Shale Talus Slope Woodland |
 Printer Friendly Version (PDF) |
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: G3G4
A Global Rarity Rank of G3G4 means: Vulnerable globally, or Apparently Secure -- At moderate risk of extinction, with relatively few populations or locations in the world, few individuals, and/or restricted range; or uncommon but not rare globally; 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 single conservation status. Did you know? What is talus? Talus, or scree, is a steep 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 the rate of erosion; for example, shale or rapidly eroding sandstone forms unstable, small, loose talus. The unstable nature of shale results in uneven slopes and many rock crevices. Other rocky types, such as hard dolostone caprock, produces stable, very large talus that provides habitat for much larger organisms. |

| State Ranking Justification | [-] |
There are probably less than a couple hundred occurrences statewide. A few documented occurrences have good viability and few are protected on public land or private conservation land. This community is limited to regions of the state with shale bedrock/talus outcrops, and there are very few 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 that include development, trampling by visitors, and invasive species.
| Short-term Trends | [-] |
The number and acreage of shale talus slope woodlands in New York have probably declined slightly in recent decades as a result of development, trampling by visitors, and invasive species.
| Long-term Trends | [-] |
The number and acreage of shale talus slope woodlands in New York have probably declined moderately from historical numbers likely correlated with past development, trampling by visitors, and invasive species.
