Facts
Slender rock-brake has a circumboreal distribution, and in North America its range is disjunct in the northeastern and northwestern regions. In New England it is rare, and found on high-pH rocks and cliffs. The above-ground parts whither by late summer.
Habitat
Cliffs, balds, or ledges, ridges or ledges
New England distribution
Adapted from BONAP data
Native: indigenous.
Non-native: introduced (intentionally or unintentionally); has become naturalized.
County documented: documented to exist in the county by evidence (herbarium specimen, photograph). Also covers those considered historical (not seen in 20 years).
State documented: documented to exist in the state, but not documented to a county within the state. Also covers those considered historical (not seen in 20 years).
Note: when native and non-native populations both exist in a county, only native status is shown on the map.
