The Heard Natural Science Museum & Wildlife Sanctuary, in McKinney Texas, is the result of Bessie Heard’s vision for the future and her commitment to the community and North Texas. Founded in 1967, the Heard consists of a 289 acre wildlife sanctuary and a natural science museum for the primary purpose of educating children about nature. The Heard exists to bring nature and people together to discover, enjoy, experience, restore, and preserve our priceless environment. The Heard sanctuary has five habitats including blackland prairie, wetlands, bottomland forest, upland forest and white rock escarpment.  Over 6.5 miles of hiking trails are available for the public to enjoy and explore. In keeping with Miss Heard’s vision, the Heard’s purpose is threefold: education, conservation, and preservation. Through education, particularly for young people, the Heard emphasizes an appreciation of nature and its conservation.
