Proceedings of the North American Prairie Conferences
The habitat consideted in this study is a 19.8-acre (8.0-hectare) prairie relict, which is part of the 296-acre (120-hectare) park (Jennings Environmental Education Center), and it is located in northwest Pennsylvania (Butler County). This prairie remnant is one of the easternmost existing relicts of the once widespread post-glacial prairies. The focus of this paper is to present an overview of the natural history of the Jennings Prairie with emphasis on preservation practices that have occurred since its discovery, in 1905, and management approaches aimed at the conservation of this habitat. The maintenance of its 225 native plant species requires human …
