US Fish and Wildlife Service and the USA National Phenology Network

Understanding the seasonal cycles of plants and animals, how they are changing, and how these changes can inform management, operations, and interpretation is critical to the mission of the US Fish and Wildlife Service (FWS): to work with others to conserve, protect, and enhance fish, wildlife, plants, and their habitats for the continuing benefit of the American people. Phenology monitoring is particularly relevant to the management of national wildlife refuges.
