Woodland Rush Juncus subcaudatus (Engelm.) Coville & Blake |
Monocots |  Printer Friendly Version (PDF) |
Family: Rush Family (Juncaceae)
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: 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: 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 species belongs to a group of Juncus with tails on the seeds, but since the tail is shorter than the tail of Canada rush its species name, meaning somewhat tailed, refects that. |

| State Ranking Justification | [-] |
There are three existing populations but one of them has no information about condition or numbers. One population is in good condition and one in excellent condition. There are 15 historical occurrences but many of these are from Western Long Island and considered extirpated.
| Short-term Trends | [-] |
The species has been in decline in recent years. About half of the existing populations that were found since 1985 have not been found again because of hydrology changes or habitat alteration. The last new population was found in 1999.
| Long-term Trends | [-] |
This species was never common in New York and many of its historical records from Nassau County are probably gone. The decline in the long-term trend is a result of habitat alteration and hydrology changes in the highly developed areas where it occurs.
