To better acquaint you with the natural history of the Keystone State, we have packaged together three portable references―Birds, Trees & Wildflowers, and Wildlife―in an attractive acetate bag. Each guide features beautiful illustrations of approximately 100 common species, as well as an ecoregion map showing top bird-finding, botanical, or wildlife-viewing hotspots. Laminated for durability, these lightweight, 12-panel folding pocket guides comprise a comprehensive three-pack for educators, learners, naturalists, birders, botanists, and wildlife enthusiasts who wish to learn more about over 300 representative species typical of Pennsylvania.
