Polypodium appalachianum

Appalachian rock polypody, Appalachian polypody

Polypodiaceae

Polypodium

Perennial

Rims of cliffs, ledges, tops of boulders in forests, and talus slopes on thin mesic soil over rocks. Distinctions in habitat preferences between this and the very closely related P. virginianum as well as the hybrid between the two (P. x incognitum) have not been detected.

Since this is a relatively recently described species that refined the description of Polypodium virginianum, some records of Polypodium appalachianum are likely buried in vouchers labeled as Polypodium virginianum.

Listed Status:	(New York):Rare plants have been protected in New York State since 1933. After a long history of expanded protection efforts, the latest regulation was enacted in June 1989 and includes three rarity categories (endangered, threatened, and rare) and one non-rare protection category (exploitably vulnerable). Rare plants included on the list are protected under New York State Environmental Conservation Law section 9-1503. Part (f) of the law reads as follows: "It is a violation for any person, anywhere in the state to pick, pluck, sever, remove, damage by the application of herbicides or defoliants, or carry away, without the consent of the owner, any protected plant. Each protected plant so picked, plucked, severed, removed, damaged or carried away shall constitute a separate violation." Violators of the regulation are subject to fines of $25 per plant illegally taken. At this time, the Atlas only identifies those species listed as threatened or endangered.
Endangered: 5 or fewer extant sites, or fewer than 1,000 individuals, or restricted to fewer than 4 U.S.G.S. 7 1/2 minute topographical maps, or species listed as endangered by the U. S. Department of Interior, as enumerated in the Code of Federal Regulations 50 CFR 17.11.
Threatened: 6 to fewer than 20 extant sites, or 1,000 to fewer than 3,000 individuals, or restricted to not less than 4 or more than 7 U.S.G.S. 7 1/2 minute topographical maps, or listed as threatened by the U. S. Department of the Interior, as enumerated in the Code of Federal Regulations 50 CFR 17.11.
Rare: 20 to 35 extant sites, or 3,000 to 5,000 individuals statewide.
Exploitably vulnerable:	listed species are likely to become threatened in the near future throughout all or a significant portion of their range within the state if causal factors continue unchecked.

Listed Status: US	(U.S.) Source - List of Endangered and Threatened Wildlife and Plants under the provisions of the Endangered Species Act of 1973, as amended.
Endangered:	Any species which is in danger of extinction throughout all or a significant portion of its range.
Threatened:	Any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range.

OBL:	Obligate Wetland. Occurs almost always (estimated probability 99%) under natural conditions in wetlands.
FACW:	Facultative Wetland. Usually occurs in wetlands (estimated probability 67%-99%), but occasionally found in non-wetlands.
FAC:	Facultative. Equally likely to occur in wetlands or non-wetlands (estimated probability 34%-66%).
FACU:	Facultative Upland. Usually occurs in non-wetlands (estimated probability 67%-99%), but occasionally found in wetlands (estimated probability 1%-33%).
