Signs of the Seasons: A New England Phenology Program

Contact email:

Using their backyards as laboratories, participants in the Signs of the Seasons program help scientists document the local effects of global climate change. Hundreds are trained to observe and record the phenology (seasonal changes) of common plants and animals living in their own communities – a citizen science project that fills a gap in regional climate research. Volunteers across Maine and now New Hampshire make observations on 20 species both terrestrial and marine. The collected data are made available to our collaborating scientists and resource managers.
