Grass Productivity is a prodigiously documented textbook of scientific information concerning every aspect of management "where the cow and grass meet." Andre Voisin's "rational grazing" method maximizes productivity in both grass and cattle operations.

Colorado's elevation range of more than 11,000 feet creates a wide variety of habitats that supports a spectacular diversity of grasses. With 335 known species, Colorado has one of the most diverse and extensive grass floras in the United States.

Comprehensive coverage, useful keys, and detailed species descriptions in Grasses of Colorado will make this volume the standard reference for years to come. Robert B. Shaw provides overviews of Colorado's physiography and ecoregions and introduces the grass plant in plain, enjoyable text. He includes a checklist of Colorado grasses, a bibliography, and a glossary of terms that may be unfamiliar to nonspecialists. Line drawings, state distribution maps, and habitat notes for each species enable accurate plant identification, familiarity with regional ecogeography, and increased understanding of plant ecology of the Rocky Mountains.

A monumental accomplishment certain to become the standard work on the subject, Grasses of Colorado synthesizes existing literature and incorporates recent scientific findings to offer a complete, current reference.

Missouri's diverse landscapes, geology, and climate have endowed the state with a rich and varied grass flora. From tallgrass prairies to forested Ozarks to Mississippi lowlands, the state offers an array of grasses that can be classified into six subfamilies of the Poaceae, eighteen tribes, and eighty-seven genera.

Significant changes have been made in grass classification since the first edition of The Grasses of Missouri was published in 1961, resulting in an increased emphasis on phyletic criteria. Recognizing the recent advances in classification and changes in nomenclature, as well as new additions to the flora, this newly revised edition serves as a compilation of the native and naturalized species and subspecific taxa found in Missouri.

Formerly divided into two subfamilies, the Festucoideae and Panicoideae, the state's grass flora is now represented by six subfamilies. While the Panicoideae have remained intact, the traditional Festucoideae are now separated into smaller, more cohesive groupings. Further revisions have resulted in eighteen tribes compared to the twelve identified in the first edition.

Covering more than 275 species and subspecific entities, The Grasses of Missouri is an essential research tool for identifying grasses, complete with working keys, descriptions, line drawings, distributions, a glossary, and a bibliography. The professional and lay person alike will benefit from this indispensable manual.

There is no easy way to identify grasses. And no one understands this better than H.D. Harrington, who observed thousands of students struggle and learn. His clear, concise, and well-organized guide will continue to be a basic and essential text for use in the classroom or in the field. The book contains over 500 drawings and an illustrated glossary.

Settlers crossing the tallgrass prairie in the early 1800s were greeted by a seemingly endless landscape of wildflowers and grasses, one of the most diverse ecosystems on our planet. Today, although the tallgrass prairie has been reduced to a tiny percentage of its former expanse, people are working to restore and reconstruct prairie communities. This lavishly illustrated guide to seeds and seedlings, crafted by Tallgrass Prairie Center botanist Dave Williams and illustrator Brent Butler, will insure that everyone from urban gardeners to grassland managers can properly identify and germinate seventy-two species of tallgrass wildflowers and grasses in eastern North Dakota, eastern South Dakota, southwestern Minnesota, southwestern Wisconsin, northern Illinois, northwestern Indiana, Iowa, eastern Nebraska, eastern Kansas, northwestern Missouri, and eastern Oklahoma.

Williams has created a brilliant, nearly foolproof system of identification and verification. Two primary keys lead to eleven secondary keys that link to characteristic groups of tallgrass plants: seven groups for wildflowers and four groups for grasses. To identify a seedling, use the primary key to discover its place in the secondary key, then turn to that characteristic group to find your seedling. Circles on each full seedling photograph correspond to close-up photographs; triangles on these close-ups illustrate information in the text to further pinpoint identification. Drawings of leaves illuminate exact identification, and enlarged photographs of each seed provide yet another way to confirm identification.

Thousands of seeds were sprouted in the Tallgrass Prairie Center’s greenhouse to provide seedlings close in size and development to those grown in the field near the end of their first season; research and photography took place over four years. Williams’s text for each species includes a thorough description, a comparison of similar species, and guidance for germination and growth. A complete glossary supports the text, which is concise but detailed enough to be accessible to beginning prairie enthusiasts.

Anyone in the Upper Midwest who wishes to preserve the native vegetation of prairie remnants or reconstruct a tallgrass prairie of whatever size—from home gardens to schoolyards to roadsides to large acreages—will benefit from the hundreds of photographs and drawings and the precise text in this meticulously prepared guide.
