Abstract/ Summary

Signs of the Seasons (SOS) is an environmental monitoring and education program for Maine citizens of all ages. Participants contribute to scientists' understanding of the local effects of climate change by observing and recording phenology, the seasonal changes of common plants and animals, in their own backyards and communities. The University of Maine Cooperative Extension and Maine Sea Grant developed the program in 2010, and co-coordinate the program's volunteer services, research collaborations, and public outreach. In 2012, University of New Hampshire Cooperative Extension and New Hampshire Sea Grant joined the effort, and have extended the program to volunteers and research partners in New Hampshire. We are a Partner Program of the USA National Phenology Network, and we work closely with many other research and outreach partners, including the National Park Service, U.S. Fish and Wildlife Service, Maine Audubon, Schoodic Education and Research Center, Coastal Maine Botanical Gardens, and faculty at the University of Maine, Maine Maritime Academy, and the University of New Hampshire.
