"This publication is the result of a half-day symposium, "Ecology, management, and sustainability of western grassland ecosystems" held at The Wildlife Society's First Annual Technical Conference, September 22-26, 1994 in Albuquerque, NM. The purpose of the symposium was to review and synthesize information about the structure, function, and components of steppe and desert grassland ecosystems in the western United States with special emphasis on the ecological roles and requirements of wildlife species. This work, designed to draw attention to some wildlife topics that have been particularly neglected for western grasslands, represents a cross-section of the papers orally presented at the symposium as well as some additional papers solicited afterwards. To provide a quality product, a minimum of two peer reviews were solicited for each manuscript, and authors were instructed to revise manuscripts based on editor's and referees' comments. Land managers, range conservationists, wildlife biologists, ecologists, and private citizens interested in sustaining the ecological health, productivity, and biological diversity of western grassland ecosystems should find this publication valuable."
