In response to the Strategic Plan for Climate Change and the proposed Action Plan for Climate Change, the U.S. Fish and Wildlife Service (USFWS) National Wildlife Refuge System (NWRS) is collaborating with the USA National Phenology Network (USA-NPN) and its online phenology monitoring program, Nature’s Notebook, to monitor phenology throughout the Refuge System. The organizations share common goals of understanding and communicating patterns in the phenology of plants, animals, and landscapes, especially in response to climate change.
