Adopt a Prairie Program


The Adopt-A-Prairie Program gives volunteer groups the opportunity to engage in the restoration and maintenance of the Blackland Prairie remnants found in Dallas parks. Fourteen prairie remnants totaling more than 162 acres have been identified, of which seven prairie parcels have been adopted by various groups. The prairie remnants were assessed based on their biological diversity, abundance of invasive species and overall management challenges. Learn how you or your organization can adopt a prairie by submitting an Adopt a Prairie Form.
