Important habitats in and around Davis include riparian, freshwater wetlands, vernal pools, valley oak woodlands, grasslands, and streams. Even agricultural croplands and irrigation ditches provide valuable habitat. This diversity of habitats is important for migratory birds, fisheries, and rare species. Migratory birds stopover in Davis on their annual migrations along the Pacific Flyway as they move from as far as Canada and South America. Anadromous fish are once again using Putah Creek on their travels between the Pacific Ocean and valley or foothill spawning locations.
