This resource from the University of Maine introduces students to phenology, the observation of the seasonal life cycle phases of plants and animals, and then highlights the work of Signs of the Seasons, a volunteer observation program that provides scientists with data to track the local impacts of global climate change. This resource features clear text and figures, colorful photographs, and is well cited, including many peer reviewed sources. After an introduction to phenology and the Signs of the Seasons program, the resource focuses heavily on how citizen investigators are providing the crucial data to understand how climate change is impacting the sugar maple, an important species in Maine’s economy. The Phenology Observation Portal is linked, a great source for independent study. The page closes with a call for more volunteer observers and an interest form is linked. This resource clearly shows the work being done to understand an important impact of climate change and is recommended for teaching.
