Jennings provides a unique combination of prairie and forest, which offers a wide array of resource and education opportunities. One of the park’s main features, the 20-acre prairie ecosystem, is home to distinctive prairie plants and the endangered massasauga rattlesnake. The most noteworthy and spectacular prairie flower is the blazing star. Jennings was the first reserve established in Pennsylvania to protect an individual plant species and remains the only public and protected prairie in the Commonwealth.
