San Bernard National Wildlife Refuge and the Columbia Bottomlands

Nestled along the Texas coast lies a hidden gem: the Columbia Bottomlands. Essential to the region’s climate resilience and to the 239 million birds who find refuge there each year, this landscape is similarly precious to the 75,000 annual visitors who’ve discovered its charms. That’s why we’ve spent decades protecting more than 7,800 acres in and around San Bernard National Wildlife Refuge, which contains much of this remaining historic ecosystem.

Within two hours of Houston and situated within the Central Flyway, an important migration path, lush hardwood forest and coastal wetlands provide a vital sanctuary for millions of migratory ducks, geese, and songbirds each year—not to mention reptiles, amphibians, mammals, and insects. Its rich biodiversity includes moss-draped coastal live oaks and pollinator-friendly native plants, making it a serene and beautiful spot for recreation, as well. In a local claim to fame, the refuge also contains the San Bernard Oak, an award-winning tree measuring more than 30 feet in circumference, with a height of 67 feet and a crown spread of 100 feet.

Trust for Public Land has long championed the protection of this unique landscape—which contains hiking trails, a drivable birding loop, and a wheelchair accessible observation platform—dating back to our first parcel, the Big Pond tract, which was added in 1999. Successful collaborations with local landowners and agencies such as the U.S. Fish and Wildlife Service have led to numerous acquisitions since then—including one funded by the Land and Water Conservation Fund.  

Our most recent addition, 32 acres near the town of West Columbia, was completed in 2025 in partnership with Cradle of Texas Land Conservancy, continuing our legacy of conservation in the region. Though not in the refuge proper, the land is adjacent to twin lakes totaling 300 acres and will serve as a stepping stone along the Central Flyway, guiding birds on their trek to northern breeding grounds. It will be managed by the Brazoria County Parks Department, which aims to enhance flood management, improve public access, and expand water-based recreational opportunities.
