Ecosystem management requires understanding how the ecological effects of forest fire interact with slower, more subtle processes such as succession and soil development to generate landscape-scale vegetation patterns. A long time perspective is required to study these interactions because the results manifest themselves over centuries, and are affected by climate variability. The primary objective of this project is to refine paleoecological methods to document changes in spatial patterns of fire and vegetation over the last 1000 years in a network of sites across a 450,000 ha sand plain in northwestern Wisconsin. The project will provide perspective for ecological studies and management goals and will involve students at two state universities and one liberal arts college in an interdisciplinary educational experience. Results will be shared with the Wisconsin Department of Natural Resources and Chequamegon-Nicolet National Forest, who are restoring ecosystem processes and structure to protect rare species and communities on the sand plain.

生态系统管理需要了解森林火的生态影响如何与较慢，更微妙的过程（例如继任和土壤发展）相互作用，以产生景观规模的植被模式。需要长时间的观点来研究这些相互作用，因为结果在几个世纪以来都表现出来，并受到气候变异性的影响。 该项目的主要目的是在过去1000年中，在威斯康星州西北部450,000公顷的沙滩上的网络中，在过去1000年中，在过去1000年中使用古生物学方法来记录火灾和植被的空间变化。该项目将为生态研究和管理目标提供观点，并将在两所州立大学和一所文科学院的学生参与跨学科的教育经验中。结果将与威斯康星州自然资源部和Chequamegon-Nicolet国家森林共享，他们正在恢复生态系统过程和结构，以保护沙平原上的稀有物种和社区。
