Identifying Trees of the East
All-season field guide for identifying common trees of eastern NA This popular, field-tested guide for identifying trees in any season, not just when they are in full leaf, features 600 color photos and 200 line drawings showing bark, branching patterns, fruits, flowers, nuts, and overall appearance in addition to leaf color and shape. Accompanying text describes common locations and identifying characteristics. Covers every common tree in eastern North America, updated with the latest taxonomy and 130 range maps. Created for in-the-field or at-home use, this helpful guide includes an easy-to-use key to facilitate putting a name to a tree.

Deep Canyon and Subalpine Riparian and Wetland Plant Associations of the Malheur, Umatilla, and Wallowa-Whitman National Forests
This guide presents a classification of the deep canyon and subalpine riparian and wetland vegetation types of the Malheur, Umatilla, and Wallowa-Whitman National Forests. A primary goal of the deep canyon and subalpine riparian and wetland classification was a seamless linkage with the midmontane northeastern Oregon riparian and wetland classification provided by Crowe and Clausnitzer in 1997. The classification is based on potential natural vegetation and follows directly from the plant association concept for riparian zones. The 95 vegetation types classified across the three national forests were organized into 16 vegetation series, and included some 45 vegetation types not previously cl...

The Ribbon of Green
Woody wetlands constitute a relatively small but extremely important part of the landscape in the southwestern United States. These riparian habitats support more than one-third of the regionÕs vascular plant species, are home to a variety of wildlife, and provide essential havens for dozens of migratory animals. Because of their limited size and disproportionately high biological value, the goal of protecting wetland environments frequently takes priority over nearly all other habitat types. In The Ribbon of Green, hydrologists Robert H. Webb, and Stanley A. Leake and botanist Raymond M. Turner examine the factors that affect the stability of woody riparian vegetation, one of the largest c...
