Did you know?
Even though this beach plant seems secure on Long Island, our state has the most populations in the world and the species is much more rare in other parts of its range.
|State Ranking Justification||
There are 43 existing populations but about half of them are small with less than 100 plants. There are no other older populations which have not been rediscovered. Numbers fluctuate from year to year in its dynamic beach habitat so quantity and quality of populations are based upon five-year averages.
Short-term trends seem stable although there can be wide fluctuations in plant numbers from year to year.
Populations have remained relatively stable since it was first documented in 1861 and New York harbors the largest number of populations in the world.
