LTREB: Trajectory for the recovery of stream ecosystem structure and function during reforestation

河流恢复是一个价值数十亿美元的产业，然而，缺乏有关恢复工作的有效性的信息，创造了一个需要长期的河流生态系统恢复后的研究。在白色粘土溪流域的恢复涉及草地和牧场与本地落叶树和入侵植物的清除重新造林。物理环境的变化顺序（例如，水流中的水温，光的利用率），水生生物群落中（例如，物种组成，营养动力学），并在白色粘土溪内的营养物的命运将被研究种植的河边落叶林的生长和成熟。该项目将建立在河流恢复的长期研究基础上，增加我们对恢复后生态变化的基本理解，并为负责实施恢复工作的资源管理人员提供信息。其他更广泛的影响将包括为期一周的研讨会，为教师从东南宾夕法尼亚州和北方特拉华州介绍他们的研究在白色粘土溪。 初中和高中教师将接受长期环境数据使用方面的培训，提高他们使用生态数据的能力，以提高学生的数学技能、分析能力、环境知识和对科学本质的理解。

Stream restoration is a multi-billion dollar industry, however the dearth of information about the efficacy of restoration efforts has created a need for long term studies of stream ecosystem recovery following restoration. Restoration in the White Clay Creek watershed has involved reforestation of meadows and pastures with native deciduous trees and the removal of invasive plants. The sequence of changes in the physical environment (e.g., water temperature, light availability in the stream), in aquatic biological communities (e.g., species composition, trophic dynamics), and in the fate of nutrients within White Clay Creek will be studied as the planted streamside deciduous forest grows and matures. This project will build on a long term study of stream restoration, adding to our basic understanding of ecological change following restoration and informing resource managers tasked with implementing restoration efforts. Additional broader impacts will include week-long workshops for teachers from SE Pennsylvania and Northern Delaware to introduce them to research at White Clay Creek. Middle and high school teachers will be trained in the use of long term environmental data, enhancing their ability to use ecological data to enhance students' math skills, analytical abilities, and their environmental knowledge and understanding of the nature of science.
