This pocket-sized card set provides rangeland managers with an easy-to-use photographic guide to 52 of the most important range and pasture plants. Spiral bound and printed on sturdy laminated paper this resource will hold up to rough service in the field. Each entry contains common and scientific name, lifecycle, habitat, elevation, forage quality, and general information . Also includes a comparison table of USDA Plant Database to Jepson e-flora scientific names and a summary table of the covered plants showing their life cycle, habitat, elevation, and forage value at a glance.

Field Guide to the Grasses of Oregon and Washington is an illustrated guide to all 376 species, subspecies, and varieties of grasses--both native and introduced--that grow wild in Oregon and Washington. It also has broad applicability in neighboring states and provinces. Grasses are important functional components in a variety of ecosystems and are highly valued for habitat restoration in numerous habitats, ranging from wetlands to deserts, and from sea level to alpine. They are important weeds and are also cultivated as ornamentals. This guide covers the entire spectrum of grasses from weedy invaders to rare native species. Identifying grasses can be challenging. The grass family is one of the most diverse plant families in the region, and differences between species can be both subtle and minute. This guide provides identification keys, species descriptions, photographs of each species (both in the field and through a microscope), habitats, and range maps. Users will especially appreciate the macrophotographs that illustrate hard-to-see, diagnostic features. Biologists, land managers, botanists, and consultants, as well as plant professionals, home gardeners, and amateur plant enthusiasts, will find this guide an indispensable reference for identifying all the grasses they encounter in the diverse habitats of Oregon and Washington.

Rangelands comprise between 40 and 50 percent of all U.S. land and serve the nation both as productive areas for wildlife, recreational use, and livestock grazing and as watersheds. The health and management of rangelands have been matters for scientific inquiry and public debate since the 1880s, when reports of widespread range degradation and livestock losses led to the first attempts to inventory and classify rangelands. Scientists are now questioning the utility of current methods of rangeland classification and inventory, as well as the data available to determine whether rangelands are being degraded. These experts, who are using the same methods and data, have come to different conclusions. This book examines the scientific basis of methods used by federal agencies to inventory, classify, and monitor rangelands; it assesses the success of these methods; and it recommends improvements. The book's findings and recommendations are of interest to the public; scientists; ranchers; and local, state, and federal policymakers.

Flora of the Pacific Northwest, first published in 1973, became an instant classic for its innovative style of providing species descriptions in the identification keys, and for its comprehensive illustrations of nearly all treated taxa (species, subspecies, and varieties). Students rely on it as an essential primer, while veteran botanists and natural resource managers use it as the definitive reference for the region�s flora. This completely revised and updated edition captures the advances in vascular plant systematics over the decades since publication of the first edition. These advances, together with significant changes in plant nomenclature, the description of taxa new to science from the region, and the recent documentation of new native and nonnative species in the Pacific Northwest required a thorough revision of this authoritative work. Flora of the Pacific Northwest covers all of Washington, the northern half of Oregon, Idaho north of the Snake River Plain, the mountainous portion of western Montana, and the southern portion of British Columbia. It accounts for the wild-growing native and introduced vascular plants falling within those boundaries and includes: Treatment of 5,545 taxa (more than 1,000 taxa added from the first edition) Illustrations for 4,716 taxa (1,382 more than the first edition) Nomenclature changes for more than 40 percent of the taxa included in the first edition These enhancements make this new edition the most comprehensive reference on Pacific Northwest vascular plants for professional and amateur botanists, ecologists, rare plant biologists, plant taxonomy instructors, land managers, nursery professionals, and gardeners.

A comprehensive assessment of the effects of climate change on global grasslands and the mitigating role that ecologists can play.
