Turkey Mountain, Tulsa’s best-loved and most utilized outdoor recreation site, is part of the endangered Cross Timbers ecoregion in Oklahoma. The MVVA Master Plan for Turkey Mountain—a landscape now surrounded by urban development, highways, and railroad tracks—restores the area’s ecological complexity and health, facilitates access, enhances the quality of its hiking and biking trails, and provides a variety of new recreational facilities. Developed in collaboration with Tulsa’s River Parks Authority, critical stakeholder groups, wetland engineers, and controlled burn specialists, the plan will return the degraded forest to its original form: a collage of native prairies, savannas, and woodlands.
