Preserve Features

A major stopping point for migratory birds and containing the remnants of an extensive Upper Cretaceous swamp and a specie of palms that was previously not thought to be located this far north, this Preserve represents one of the most environmentally unique and sensitive sites in North Texas.

Because the water features are so extensive and because the ecosystem is so sensitive, please note that for safety reasons it is not possible to have the Preserve be open to the general public at this time.  However, a system of boardwalks and observation points which will allow the public to safely enjoy the Preserve is planned.  Until then, the Preserve is only open by permit to universities, governmental agencies, and credentialed researchers.
