National Phenology Network

The USA National Phenology Network brings together citizen scientists, government agencies, nonprofit groups, educators, and students to monitor the impact of climate change on plants and animals in the United States.

Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and other variations in climate, as well as habitat factors. The National Phenology Network provides data and information on the timing of these events in plants and animals to ensure the well-being of humans, ecosystems, and natural resources.
