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灾的生态影响如何与演替和土壤发育等更缓慢、更微妙的过程相互作用，以产生景观规模的植被模式。研究这些相互作用需要一个长期的视角，因为结果会在几个世纪内显现出来，并受到气候变异性的影响。该项目的主要目标是改进古生态方法，以记录过去1000年来威斯康星州西北部一片45万公顷沙质平原上的地点网络中火灾和植被的空间模式变化。该项目将为生态研究和管理目标提供视角，并将让两所州立大学和一所文理学院的学生参与跨学科教育体验。结果将与威斯康星州自然资源部和Chequamegon-Nicolet国家森林分享，他们正在恢复生态系统过程和结构，以保护沙地平原上的稀有物种和群落。
