Do More than Just Leaf Peep: The Foliage Network relies on the observations of people across the country.
Broadly, this is an example of phenology, the study of the timing of natural phenomena. As the climate changes, phenology is becoming an increasingly important area of research. Will pollinating insects that emerge each spring find the same flowers that bloom for short periods of time as the climate changes? Will migrating birds find the right seeds? Will inn-keepers see the same influx of tourists for leaf-peeping season, and will maple syrup makers see a robust flow of sap from their trees? These are the types of questions that phenology asks, and that citizen scientists can help to answer.
