Summer Wetlands Program

Applications closed

The 2026 application period ran January 9 – February 1. Check back in January 2027 for next year’s program!

Nesting and brood-rearing habitat for shorebirds and waterfowl

The BirdReturns Summer Wetland Program incentivizes private wetland managers to provide nesting and brood-rearing habitat for shorebirds and waterfowl. By flooding-up suitable wetland units in spring and maintaining habitat through the summer, wetland managers create this much-needed habitat for nesting birds — units must be able to maintain deep flooding and conduct a gradual drawdown.

Applicants may apply for both the Spring and Summer Wetland Programs, as long as each application covers a separate wetland unit that can be independently managed to meet program requirements.

Delayed Drawdown

Permanent wetland. Fully flooded April 1 – October 1. Suisun properties must complete a spring leach cycle by draining and reflooding to target depth by April 1.

Nurturing Brood Habitat

Brood habitat plays a critical role in supporting healthy waterfowl populations — nesting areas, refuge during molting, and protection for vulnerable ducklings. During the driest months, when natural wetland habitat is limited, brood ponds supply the food, cover, and stable water conditions that support successful breeding and chick survival

Did you know?

More than 60% of mallards harvested in California hatched here, making the state a critical breeding region for waterfowl populations.

As wetlands draw down, invertebrates concentrate in the shrinking water — a critical protein source fueling shorebirds heading into fall migration and waterfowl going through molt.

Molting ducks are flightless for three to four weeks each summer, making undisturbed, well-managed wetlands essential shelter from predators during this vulnerable period.

This little black-necked stilt was hatched for just a few hours. His two siblings were already walking around in the swamp for a day and there’s one last egg in the nest. Mama waited for this new hatchling to dry then decided to guide him to the swamp so
