Sedges are key members of many Northwest ecosystems, performing critical roles in wetlands, prairies, savannas, steppes, and forests. They are often the dominant ground cover in flood plains, along stream banks, and in wet meadows and marshes. Their extensive, fibrous root systems prevent erosion by binding soils, while their dense foliage traps sediment, making them critical elements in the restoration of wetland and riparian systems. Field Guide to the Sedges of the Pacific Northwest is the first illustrated guide to all 164 species, subspecies, and varieties in the genus Carex that occur in Oregon and Washington and throughout the Pacific Northwest. Sedges can be challenging to identify with differences between species based on small, technical characters. After nearly fifteen years of research, Oregon botanists of the Carex Working Group have written this comprehensive guide, complete with identification keys, descriptions, color photographs, and distribution maps for each species, providing users with helpful tools and tips for identifying the plants in this challenging group. Information about sedge ecology, habitat management and restoration, ethnobotanical uses, and propagation enhances the guide's utility. The Field Guide provides a comprehensive and essential resource for botanists, land managers, restoration ecologists, and plant enthusiasts. And, as the genus Carex becomes increasingly important amongst landscapers, nurseries, and gardeners, the guide will serve as a handy tool for choosing Northwest natives for the garden.
