This is our only fern that acts as a true vine, although it doesn't climb very high.
|State Ranking Justification||
There are four existing populations but they are small and only one of them is on protected land. There are only five other historical locations for this fern in New York, from 1868 to 1965, but three of them no longer exist.
The short-term trend appears stable as existing populations have not increased or decreased.
This plant has always been very rare in New York with less than 5 populations. It will continue to exist at low levels into the foreseeable future.
