Family: Wood-fern Family (Dryopteridaceae)

State Protection: Endangered
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 minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior.

Federal Protection: Not Listed

State Rarity Rank: S1S2
A State Rarity Rank of S1S2 means: Critically Imperiled or Imperiled in New York - Especially or very vulnerable to disappearing from New York due to rarity or other factors; typically 20 or fewer populations or locations in New York, very few individuals, very restricted range, few remaining acres (or miles of stream), and/or steep declines. More information is needed to assign a single conservation status.

Global Rarity Rank: G5
A Global Rarity Rank of G5 means: This species is demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.


Did you know?
This is the smallest of our North American wood ferns. The fragrance, which some people liken to primrose, comes from the tiny glandular hairs on the fronds. The New York plants are at the southeastern limit of the species range.

State Ranking Justification [-]
There are four known populations and at least ten historical populations. These historical locations are in the Adirondacks in areas that have likely remained unchanged since the plants were last reported. Surveys focused on these areas will likely lead to the rediscovery of these populations. Few threats are known for this plant, mainly because it is found in relatively difficult to access areas.
