The John Bunker Sands Wetland Center Mission Statement
The mission of the John Bunker Sands Wetland Center is to educate the public and provide research opportunities in the areas of water quality and supply, wildlife management, and wetland systems.
The Wetland Center facility provides opportunities for research, education, wildlife observation, and community gatherings within a comfortable, environmentally-conscious building. The Center partners with area school districts, wildlife and conservation organizations, and research institutions.
The Wetland Center resides in the middle of the East Fork Wetland Project which was designed to filter treated wastewater and supplement the water supply for 1.7 million people living in north Texas. It is one of the largest constructed wetlands on the United States and is located along the banks of the East Fork of the Trinity River, 25 miles southeast of Dallas, TX An additional 1,200 acres of bottomland hardwood forest with seasonal shallow wetlands are located on the opposite side of the river and is dedicated as a wetland mitigation bank in honor of John Bunker Sands called the Bunker Sands Mitigation Bank.
These ideas reflect and extend the vision of Bunker Sands, a holistic ranch management advocate, who directed the creation of over 2,100 wetland acres on Rosewood Ranches properties in Kaufman, Henderson, Ellis, and Navarro counties. The constructed wetlands included seasonal emergent wetlands, scrub swamps and flooded bottomland hardwood forest. Several of the original wetlands occurred at Rosewood's Seagoville Ranch, the site of the Center and of the water reuse East Fork Wetland, developed and operated by North Texas Municipal Water District.
Created in partnership with the the Caroline Rose Hunt family through The Rosewood Corporation and the North Texas Municipal Water District, the Center hosts and provides facilities to further our community's understanding of the area's water supply challenges and the importance of habitat conservation.
