Bay Delta Campaign
Few local conservation priorities are as important as restoring and protecting the health of the San Francisco Bay and Sacramento-San Joaquin Delta. The Bay Delta is vital to California's health, economy, and culture. This complex ecosystem provides fresh water to millions, supports a thriving wildlife population, and offers countless recreational opportunities.
But the Bay Delta is in ecological collapse. With over 90% of historic tidal wetlands lost, this delicate ecosystem is under threat from invasive species, industrial runoff, climate change, and rapid development. Now, more than ever, action is needed to protect this vital landscape.
At JMLT, we’ve made it part of our mission to preserve and restore critical lands in the Bay Delta. Our campaign began with the restoration of Pacheco Marsh and is expanding to include more projects to protect the region’s fragile shorelines and waterways. Through land acquisition and restoration, we’re bringing back habitats where native plants and wildlife can thrive, while also supporting the region’s economic well-being.
Why is the Bay Delta so important?
Water Source: The Bay Delta is the hub of California's water supply, providing fresh water to two-thirds of the state's population and millions of acres of farmland.
Wildlife Habitat: Nearly half of California's migrating waterfowl and shorebirds and two-thirds of the state's spawning salmon pass through the Bay Delta. The region's salt marshes provide essential nutrients, refuge, and nursery habitat for fisheries species.
Economic Engine: The Bay Delta supports a thriving economy, providing jobs and recreational opportunities for countless people.

The Bay Delta Crisis
Despite it's critical importance, the Bay Delta is facing a growing crisis. Decades of human activities have pushed this delicate region to the brink. Pollution, habitat destruction, and the relentless march of climate change have combined to threaten its very existence.
Invasive species, industrial runoff, and rising sea levels have disrupted the Bay Delta's delicate balance. Over 90% of its historic tidal wetlands have disappeared, leaving it vulnerable to flooding and erosion.
Our Bay Delta Projects
JMLT’s Bay Delta Campaign has already taken action to restore and protect this vital ecosystem. The restoration of Pacheco Marsh and the acquisition and protection of Hoover ranch are two of our flagship projects.
Pacheco Marsh Restoration and Public Access Project
Once a salt marsh devastated by industrial activity, Pacheco Marsh is now undergoing a remarkable transformation. Located along Suisun Bay, this multi-million-dollar restoration project is bringing new life to a vibrant wetland habitat.
JMLT is creating a public access point for outdoor recreation and education. Our plans include walking trails, educational pavilions, and kayak launches, inviting the community to explore and appreciate this unique ecosystem.
Hoover Ranch Acquisition
JMLT is also working to acquire and restore 600 acres of critical habitat on Bethel Island. Hoover Ranch, a haven for migratory birds and native species, is one of the largest privately-owned properties in the Bay Delta, featuring nearly two miles of shoreline. Our restoration plans include building wetlands, improving wildlife habitats, and implementing carbon sequestration practices to address climate change.
