Background: Napa-Sonoma Marshes Wildlife Area is remote in that it covers many acres accessible only by boat, however, there are numerous sites for wildlife viewing where the wildlife area interfaces with major state highways. This wildlife area is an important area within the Pacific Flyway in terms of wintering waterfowl and migrating shorebirds just north of San Pablo Bay.
With recent restoration efforts, interpretive signage is being added to numerous sites that incorporate species and habitat as well as cultural and natural history aspects specific to the site.

The Habitat: The Napa-Sonoma Marshes Wildlife Area is primarily a wetland area of tidal influence and historic marshes. Habitats include tidal mudflats to upland grasslands defined by San Pablo Bay, Napa River, Tolay Creek, Sonoma Creek and numerous tidal sloughs.

The Experience: The marshes are a historic migration area for birds as well as an important nursery site for fish and crustaceans. Water within the wildlife area can range from fresh water run off and fresh water ponds to brackish and even hyper-saline ponds (related to former salt ponds). The Napa-Sonoma Marshes Wildlife Area has one of the largest on-going restoration projects in the Western United States (~10,000 acres).

Wildlife and Where to Find It: "Trails" at this wildlife area consist mainly of service roads and levee tops.
