Throughout the year, LINPI will make numerous volunteer activities available helping us advance our efforts to produce locally sourced plant materials for Long Island’s nursery and landscape industry as well as the general public.  Volunteering is a mutually beneficial endeavor; LINPI receives the help we need to advance our goals and our volunteers are afforded an opportunity to advance their knowledge of native plants and plant propagation.

Bailey Arboretum, Lattingtown, Nassau County

A decade ago, when Nassau County managed Bailey Arboretum, they had seven full-time employees on the premises.  Today we operate with the equivalent of two, one full-time and three part-time. You can see why volunteers are important to us!  If you have ideas for children’s activities at the upcoming Pumpkin Festival, experience handling PR, a few hours a month you can spare to stuff envelopes or manage the mailing list, a passion for pruning or weeding (or a desire to learn more) we have plenty of work to go around. Please give us a call at 571-8020 or send us an email at     We’d be very, very grateful for your help.
