Book Description
Grasses are among the most ubiquitous plants on the planet. They inhabit a wide geographic range and are found in a variety of natural habitats. The small parts of the grass flower and specialized terminology, however, can make identifying grasses a challenging endeavor. Sarah Chamberlain’s Field Guide to Grasses of the Mid-Atlantic makes identification simpler for everyone—regardless of their previous botanical knowledge. Featuring an easy-to-use dichotomous key, this is a user-friendly guide to more than 300 types of grasses found from the Blue Ridge Mountains and southern plains to the Appalachians and the Allegheny Plateau. Each major entry contains detailed species diagrams as well as common names, habitats, and distribution. The book’s opening sections outline the parts of grass flowers and describe stem, leaf, and sheath characteristics. With a wealth of illustrations, instructions on how to use the key, and a glossary of terms, Field Guide to Grasses of the Mid-Atlantic is an indispensable reference for naturalists and conservationists, botanists, land management professionals, and students and scholars of mid-Atlantic flora.

Book Description
The PA Flora Database (PFD) has its roots in the work of Edgar Wherry, John Fogg, Jr., and Herbert Wahl, the "Atlas of the Flora of PA", pub. by the Morris Arboretum of the Univ. of PA. Over a period of 40 years, Wherry and his colleagues gathered data from the major PA herbaria and manually placed a quarter of a million dots on over 3,500 maps, which are reproduced in this volume. The checklist of included taxa has undergone extensive review to reflect recent taxonomic and nomenclatural revisions. Recent discoveries have been added and distribution data has been updated. This volume also includes collections made in the 1990s in conjunction with the PA Natural Diversity Inventory. Extensive illustrations. Reprinted 1996.

Book Description
Throughout Pennsylvania, within the state forest system, are 61 officially designated Natural Areas, each offering a bit of wildness deemed worthy of protection: rare-bird breeding sites, stands of old-growth trees, fragile wetlands, ice age remnants, mineral-rich mountainsides. To experience first-hand the unique features of each natural area, nature writer Charles Fergus spent a year visiting all 61. In this information-filled book, he reports on what he found, offering readers a guided tour of some of natural Pennsylvania's most distinctive places. He also provides information on how to visit the areas, each of which is open to the public.
