This three-year study will investigate the impact that anthropogenic disturbance has on tundra land cover near Barrow Alaska. Based on photographs made over the last 50 years, anthropogenic disturbances will be documented and the evolving response by plant communities will be chronicled. Additional tests concerning the resilience and resistance of principal tundra plant communities will be examined using manipulation experiments within experimental plots. The data developed from this study will be made available in a Geographic Information System format. The concepts and parameters obtained will then be used in a geographically based Arctic System Land Transformation Model in order to examine the possible impacts of man's expanding use of the Alaskan tundra. Undergraduate students from the Barrow community will be utilized as research assistants. This project will directly link with ongoing studies of the climatological and vegetation transformations occurring in the Arctic tundra.

这项为期三年的研究将调查人为干扰对阿拉斯加巴罗附近苔原土地覆盖的影响。 根据过去50年拍摄的照片，将记录人为干扰，并记录植物群落不断变化的反应。 将在实验地块内使用操纵实验来检查关于主要冻原植物群落的复原力和抵抗力的其他测试。将以地理信息系统的格式提供从这项研究中获得的数据。 所获得的概念和参数，然后将被用于一个基于地理的北极系统土地转换模型，以检查人类的阿拉斯加苔原的扩大使用可能产生的影响。 来自巴罗社区的本科生将被用作研究助理。 该项目将与正在进行的关于北极苔原气候和植被变化的研究直接联系起来。
