Grasses are the world’s most important plants. They are the dominant species over large parts of the earth’s land surface, a fact that is reflected in the many different words that exist for grasslands, words such as prairie, veldt, palouse, and pampas to mention just a few. As a group, grasses are of major ecological importance, as soil binders and providers of shelter and food for wild animals, both large and small. Some grasses, such as wheat, rice, corn, barley, rye, tef, and sugar cane are major sources of calories for humans and their livestock; others, primarily bamboos, are used for construction, tools, paper, and fabric. More recently, the seed catalogs that tantalize gardeners each winter have borne witness to an increasing appreciation of the aesthetic value of grasses. The Manual of Grasses for North America is designed as a successor to the classic volume by Hitchcock and Chase. It reflects current taxonomic thought and includes keys, illustrations, and distribution maps for the nearly 900 native and 400 introduced species that have been found in North America north of Mexico. In addition, it presents keys and illustrations for several species that are known only in cultivation or are of major agricultural significance, either as progenitors of bread wheat and corn or as a major threat to North American agriculture because of their ability to hybridize with crop species. The Manual of Grasses for North America is a major reference work for grasses that will retain its value for many years.

The objective of this guide is to assist federal personnel, professional and amateur botanists, and interested lay persons in the identification of the rarest plant species in Wyoming. Species covered in the guide include USFWS candidate and listed Threatened and Endangered plants, USFS Sensitive species, and plants of special concern monitored by WYNDD.

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.

These experienced and highly respected nature writers have produced an outstanding field guide to the plants that grow above the tree line, at the higher elevations of the Rockies and Cascades, and other ranges of the Western Cordillera of North America. Here is comprehensive information on almost 1,200 species of trees, shrubs, wildflowers, and more, with over 2,000 illustrations: color photos, line drawings and range maps.

Features more than five hundred plants and herbs of North America providing information on their location and medicinal uses.

This book documents nearly 500 US and Canadian locations where wildlife refuges, nature preserves, and similar properties protect natural sites that lie within the North American Great Plains, from Canada's Prairie Provinces to the Texas-Mexico border. Information on site location, size, biological diversity, and the presence of especially rare or interesting flora and fauna are mentioned, as well as driving directions, mailing addresses, and phone numbers or internet addresses, as available. US federal sites include 11 national grasslands, 13 national parks, 16 national monuments, and more than 70 national wildlife refuges. State properties include nearly 100 state parks and wildlife management areas. Also included are about 60 national and provincial parks, national wildlife areas, and migratory bird sanctuaries in Canada's Prairie Provinces. Many public-access properties owned by counties, towns, and private organizations are also described.
