There are only two known populations of this plant, one being discovered in 2005, and at least six historical locations that need further survey work. This plant tends to form large stands with hundreds to thousands of culms. In New York it is a sedge of calcareous wetlands, a very limited habitat type. It may be threatened by changes to hydrology, water chemistry changes, and invasive species
There are only two populations that have been seen in recent years. One of these populations was first found in 2005. It was probably overlooked in the past. The other population is large and healthy but no exact data is available on the trends. Therefore, short term trends are not clear but might indicate that this species is currently stable.
One population has been known for at least 140 years. Another populations was just discovered in 2005 but it was probably overlooked in the past. There are approximately seven or so additional populations that are only known from historical documentation. It is unknown if these populations are still extant. Overall, long term trends are unknown.
