Phenology on the Refuges

National Wildlife Refuges across the country are using phenology monitoring through USA-NPN's Nature's Notebook program to meet both management and outreach goals. Click the Refuge icons on the map or select from the list below the map to learn more about the individual goals of these refuges and what they are finding so far.

You can also explore our Phenology Trails, which are collaborations of refuge and non-refuge partners working toward a common goal to better understand phenology:
