Ferns |  Printer Friendly Version (PDF) |
|
Family: Spleenwort Family (Aspleniaceae)
State Protection: Endangered Species 
This level of state protection means: listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 ½ minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior. Federal Protection: Not Listed State Rarity Rank: SH
A State Rarity Rank of SH means: This plant is only historically known from New York State, typically with the last plant observed over 20 years ago. Many SH plants have not been seen in 50-100 years. Global Rarity Rank: G4
A Global Rarity Rank of G4 means: This species is apparently secure globally (typically with more than 100+ populations), though it may be quite rare in parts of its range, especially at the periphery. Did you know? There have only been two historical locations of this plant in New York. One is from "a hill near Newburgh" in 1864 and the other is from the "Shawangunk Mountains" where it was observed in 1882 and 1895. More exploration of the Shawangunk cliff communities may result in its rediscovery. The plant is named for its discoverer Professor Frank H. Bradley, 1838-1879, naturalist and geologist from Indiana. The genus name Asplenium comes from a name (Asplenon) used by Dioscorides for a fern supposed to cure diseases of the spleen. |
| State Ranking Justification |
| Even though there is plenty of available habitat and numerous surveys have been conducted to find this fern, no populations are known today. There are two historical reports, one from Newburgh which is feared extirpated and one from the Shawangunk Mountains where potential habitat abounds. While this plant was last reported in New York in 1895, we still believe there is a high probability that it will be rediscovered. The most likely location for rediscovery is somewhere within the Shawangunk Mountains. |
