Dicots |  Printer Friendly Version (PDF) |
Family: Buttercup Family (Ranunculaceae)
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: Threatened
Listed as Threatened in the United States by the US Department of Interior. State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors. Global Rarity Rank: G3
A Global Rarity Rank of G3 means: This species is either rare and local throughout its range (21 to 100 occurrences), or found locally (even abundantly at some of its locations) in a restricted range (e.g. a single physiographic region), or is vulnerable to extinction throughout its range because of other factors. Did you know? Northern monk's-hood is considered one of the most beautiful rare plants in New York. It is the signature plant of New York's Eastern Chapter of the Nature Conservancy. Genetic studies are presently under way to determine its relationship with the more common Aconitum columbianum. Some taxonomists do not consider it a distinct species. |

| State Ranking Justification | [-] |
There are five viable populations with plants numbering in the hundreds for each population. There are five populations which were very small in the past and have not been seen in many years. These are probably gone. Even though these populations are isolated in the Catskill Mountains, threats are high.
| Short-term Trends | [-] |
The species can fluctuate greatly from year to year in the stream bank populations that are subject to flooding. There is less fluctuation in the wetland populations but they may be affected by deer browse from year-to-year.
| Long-term Trends | [-] |
There has been a substantial decline from population sizes that were measured in the early 1980s. This is probably due to the repeated severe flooding of Catskill streams.
