Book excerpt: 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.

Download or read book The Highlands written by Richard G. Lathrop and published by Rutgers University Press. This book was released on 2011-12-12 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Think of the Highlands as the “backyard” and “backstop” of the Philadelphia–New York–Hartford metroplex. A backyard that spans over three million acres across Pennsylvania, New York, and Connecticut, the Highlands serves as recreational open space for the metroplex’s burgeoning human population. As backstop, Highlands’ watersheds provide a ready source of high-quality drinking water for over fifteen million people. The Highlands is the first book to examine the natural and cultural landscape of this four-state region, showing how it’s distinctive and why its conservation is vital. Each chapter is written by a different leading researcher and specialist in that field, and introduces readers to another aspect of the Highlands: its geological foundations, its aquifers and watersheds, its forest ecology, its past iron industry. In the 1800s, the Highlands were mined, cutover, and then largely abandoned. Given time, the forests regenerated, the land healed, and the waters cleared. Increasingly, however, the Highlands are under assault again—polluted runoff contaminating lakes and streams, invasive species choking out the local flora and fauna, exurban sprawl blighting the rural landscape, and climate change threatening the integrity of its ecosystems. The Highlands makes a compelling case for land use planning and resource management strategies that could help ensure a sustainable future for the region, strategies that could in turn be applied to other landscapes threatened by urbanization across the country. The Highlands are a valuable resource. And now, so is The Highlands.

Download or read book The Lehigh Valley: A Natural and Environmental History written by and published by Penn State Press. This book was released on with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprising approximately 730 square miles and over half a million residents, the Lehigh Valley is the third largest metropolitan area in Pennsylvania, encompassing the cities of Allentown, Bethlehem, and Easton. Much is known about the industrial history of the valley (home to Bethlehem Steel, Mack Trucks, and Crayola crayons). But few have discovered the valley's natural history: the "endless" Blue Mountain, the spectacular raptor migrations, the wetlands and watercourses. The Lehigh Valley explores the land and the natural forces and human history that have altered it. From boulder fields to water gaps, from sinkholes to limestone caves, the valley has long had a powerful influence on the lives of its residents--and the people have had a similarly powerful effect on the valley; the text features brief profiles of some of the people who have shaped the environmental history of the area. The authors also include directions to historical and natural sites, and the book's illustrations aid visitors and naturalists in identifying the region's abundance of flora and fauna. The Lehigh Valley is a unique combination of narrative natural history, identification handbook, and travel and hiking guide. Mountain laurel, red-tailed hawks, dusky salamanders: The Lehigh Valley not only shows us what resides in this beautiful and bountiful valley, but also explains why. This illustrated guide surveys the valley's ecology, geology, history, and agriculture--and is complemented by maps and drawings of the area's plant and animal life. The Lehigh Valley will appeal to area residents, amateur naturalists, and Pennsylvania visitors with an interest in natural history.
