Annual Sandplain Gerardia Count Yields a 10 Year High!

September 2022 -- On Labor Day, board members, student interns, and the Friends' Habitat Director participated in the annual Agalinis acuta survey to count existing plants at the Hempstead Plains Preserve.  The Species, Agalinis acuta is considered a "globally rare" plant and is found in only a few locations on Long Island--with the largest source being right here at the Hempstead Plains.  

Part of the reason this whole preserve is protected, is due to the presence of this listed species.  With that comes a certain responsibility though.  Here at the plains, our management of the habitat directly affects the success of this rare plant.  With proper annual mowing during the winter months, and constant removal of large woody growth, we have maintained the historic habitat for these plants, and hope that expansion to other areas occurs in the future.

This years survey included over 3,700 plants! most of which were in full bloom during this years survey.  For some context, the count in 2021 was under 1,500, and was 2,400 in 2020.  There are many factors that affect the abundance and vigor of these plants.  The plant communities within the protected Agalinis area likely have the greatest influence, and studies show the microhabitats where Agalinis acuta are found is very unique.  If you're a blossoming botanist, this is a great research opportunity!

While they are past bloom now, we hope to see you next September for another chance to see this special plant.
