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.
