Hardcover. Zustand: New. Zustand des Schutzumschlags: New. Anisko, Anna (illustrator). 1st Edition. Black maples can tower to eighty-five feet. Artisans craft fine musical instruments from the wood of native red spruces. And in autumn, the leaves of sugar maples turn brilliant orange-gloriously coloring Penn's Woods. The naturalist, forester, or weekend observer will discover all this and more in Trees of Pennsylvania. Written by botanists at the Morris Arboretum, the official arboretum of the Commonwealth of Pennsylvania, this is the most comprehensive, authoritative, and accessible field and natural history guide to the state's tree life. Ann Rhoads and Timothy Block cover all of Pennsylvania's 195 trees, both native and naturalized. Each species is described in a concise, tabular format that includes the characteristics of leaves, branches, bark, flowers, and fruits. The authors discuss flowering and fruiting time, autumn leaf color, and the size of the largest specimen recorded within the state. Rhoads and Block further provide valuable historical, ecological, and economic information on each tree species, including how Pennsylvania's trees were used by Native Americans and early European settlers. This fully illustrated, user-friendly volume contains a combination of line drawings by botanical artist Anna Anisko, color photographs, range maps, and identification keys so readers will be able accurately to identify each tree species. It also offers useful information on the biology of trees, the history of Pennsylvania's many forests, and important lists of the endangered, threatened, and rare trees within the state. This is an indispensable guide for anyone interested in Pennsylvania's natural history and tree life. Signed by Illustrator(s).

Hardcover. Zustand: New. Zustand des Schutzumschlags: New. Anisko, Anna (illustrator). 1st Edition. From the Delaware River to the shores of Lake Erie, Pennsylvania's diverse watery habitats are home to more than 200 species of aquatic plants. In Aquatic Plants of Pennsylvania: A Complete Reference Guide, botanists Timothy A. Block and Ann Fowler Rhoads have assembled the first identification guide specific to the Keystone State yet useful throughout the Mid-Atlantic region. Organized and written in a way that will make information easily accessible to specialists and nonspecialists alike, the book highlights the diversity and vital ecological importance of this group of plants, providing photographs, illustrations, descriptions, and identification keys for all emergent, floating-leaved, and submergent aquatic plants found in the Commonwealth. An introductory chapter on aquatic plant ecology covers topics such as the evolution, form, and reproduction of aquatic plants, vegetation zones, types of aquatic ecosystems, and rare and endangered species. Information on invasive plants, such as Eurasian water-milfoil and curly pondweed, that threaten Pennsylvania's aquatic ecosystems will be especially useful to watershed organizations, citizen monitoring projects, lake managers, and natural resource agency personnel. An illustrated identification key guides the reader through a series of steps to properly identify a specimen based on its characteristics. Each of the more than 200 listings provides a plant's taxonomy, detailed description, distribution map, and expert botanical illustrations. Many also include color photographs of the plants in their natural habitats. Signed by Illustrator(s).
