Thorough, detailed dendrological coverage of North American trees, shrubs, and vines This comprehensive field guide/procedural handbook provides extraordinarily detailed descriptions of trees, shrubs, and vines of North American forests. Written at a more detailed level than most field guides, it introduces basic taxonomic concepts and methods and explains the rationale behind taxonomic classification systems. Entries include Latin and common names for each species as well as physical descriptions at various levels of maturity and for different seasons. Also noted are regional and state distributions, soil conditions, cover types, shade tolerances, and common diseases and pests. This remarkably thorough and reliable reference includes:* Detailed descriptions of more than 800 species * Hundreds of additional varieties and cultivars * 550 exquisitely detailed line drawings of leaves, bark, fruit, and seeds * Broad coverage of commercial and noncommercial species * An emphasis on the silvical features of each species * A unique section on forest community ecology and cover types* The new North American Classification System Well-organized and practical, this authoritative guide is an immensely useful resource for foresters, wildlife and field biologists, naturalists, environmental scientists, and land managers.

Savannas and barrens were major components of the historic North American landscape before it was extensively altered by agricultural and urban development during the past century. Rock outcrop plant communities and serpentine barrens are of interest because they are refugia for endemic species adapted to extreme environmental conditions. Many of these communities have been reduced to less than one per cent of their original area and are imperiled ecosystems. This book provides a coherent, readable summary of the technical information available on savannas, barrens and rock outcrop plant communities. It is organized by region into four parts: eastern south-eastern region, central/midwest region, western/south-western region, and northern region. Written by internationally recognized regional specialists, each chapter includes a description of the climate, geology, soils associated with the community, and information about its historic and current vegetation.
