Field Guide to the Grasses of the Pacific Northwest covers all 376 species, subspecies, and varieties of grasses, both native and introduced, that grow wild in Oregon and Washington. It provides two methods to identify grasses, a formal identification key and a well-illustrated text one can page through to match the grass at hand. Range maps are included. Grass terminology is defined in the glossary and the more important terms are explained in a highly readable introduction. To cope with shifting grass nomenclature, important synonyms are included in the index, referring the reader to the name used in the book. The microscope photos of small grass part (lemmas, glumes, ligules) are unusual in a field guide and essential for identification.

Grasses are important ecosystem components from sea level to the alpine zone, from wetlands to deserts. Numerous species grow in prairies, savannas, grasslands (surprise!), sagebrush steppe, and in the understories of forests. They are valued economicallys as grain crops, forage for livestock, lawns, and ornamentals, and they are reviled as weeds in both cultivated fields and wild lands. Managing grasses requires knowing what species you have, and that's where this book comes in. Using it, you can figure out the name and thus look up what is known about the grass's biology.

The Field Guide to the Sedges of the Pacific Northwest covers all 169 species, subspecies, and varieties of the genera Carex and Kobresia that occur in Oregon and Washington. The second edition includes 8 taxa only recently found in the area, updates nomenclature, and includes a revised identificaiton key. This key, tailored to the variation seen in PNW sedges, permits accurate identification. Each taxon gets a two-page spread, a page of photographs facing a page of text. The book has over 650 photos plus additional drawings. Range maps for each species incorporate the most recent distribution gathered from herbarium records and over a decade of field inventories conducted by the authors. The book includes information on sedge morphology, ecology, habitats, management and restoration.

Carex is the largest genus of plants in this region. Sedges are important, often dominant members of many wetland and riparian plant communities. They can be challenging to identify, with differences between species based on tiny characters. This guide helps the reader recognize and use these characters to identify the sedges they encounter in the diverse habitats of the Pacific Northwest. It is a valuable resource for land managers, public and private biologists, wetland regulators and consultants, and amateur plant enthusiasts.
