The Texas Master Naturalist program is designed to develop a corps of well-informed volunteers who provide education, outreach, and service dedicated to the beneficial management of natural resources and natural areas within their communities for the State of Texas. The Texas Parks and Wildlife Department and the Texas A&M AgriLife Extension serve as sponsors for the program. Trained Master Naturalist volunteers are uniquely qualified to inspire their neighbors to appreciate the natural environment, to participate in hands-on projects are local parks and preserves, and to help children and adults learn about the local natural resources. The possibilities to make a difference are endless!

One of 48 recognized chapters in Texas, the Blackland Prairie Chapter of the Texas Master Naturalist program is based in McKinney Texas. The chapter draws members from communities located in Collin and Hunt counties. Chapter meetings are held at the Heard Natural Science Museum and Wildlife Sanctuary, 1 Nature Place, McKinney, Texas 75069, on the second Tuesday of each month at 7:00 PM. Visitors are always welcome to attend.
