October, 1991 newsletter NYFA

Eighteen members of NYFA met in Riverhead, N Y on September 22 for a hike through several exemplary Long Island plant communities. The weather was sunny and warm. The first stop was the pine barrens and associated ponds in the headwaters of the Peconic River. We walked through the woods from Route 25 to the northern end of Peasy's Pond and then walked through Peasy's as far as Sandy Pond. The water level was nearly at its highest with only a small area of exposed margin. Although many of the species seen during low water years were not present, we recorded many bladderwort species and 14 species that are listed as rare in New York by the New York Natural Heritage Program.

The second stop was along the southeast side of Hubbard Creek Marsh in Flanders to visit one of Long Island's best salt marshes. Phragmites occurs only locally at this site which has both high productivity stands of low marsh cordgrass and large patches of high-salinity upper marsh.
The final stop was at the Dwarf pine barrens in the area southwest of Interchange 63 on the Sunrise Highway. We walked a old cinder road into a characteristic site with stunted pitch pine.
Base species lists were compiled from Heritage work over several years. The followings lists were made from additions by Betty Lotowycy, Barbara Conolly, Chris Mangels, Steve Clements, and David Hunt.
