Based on papers presented at a 1987 symposium, "Fire in North American Grasslands," cosponsored by the Ecological Society of America and the Botanical Society of America, this book represents an important contribution to key unanswered questions concerning the role of fire in grassland ecosystems: How often did fires occur in the past? Were they primarily natural or caused by humans? At what time of year did grasslands normally burn? How should fire be used as a management tool? What constitutes a proper prescribed burning regime both with and without grazing?
