Environmental Stewardship in Dallas

Dallas Ecology

Dallas lies between the Piney Woods of east Texas and the Great Plains in the Blackland Prairie. Rolling grasslands are laced with bottomland forests along rivers and creeks. The Trinity River runs through the city and just south of downtown is the 6,000-acre Great Trinity Forest, home to an estimated 1,300 plant and animal species.
