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.

河流恢复是一个价值数十亿美元的产业，然而，由于缺乏有关恢复工作有效性的信息，因此需要对恢复后的河流生态系统恢复进行长期研究。白粘土溪流域的恢复工作包括在草地和牧场上重新造林，种植本土落叶乔木，并清除入侵植物。随着种植的河边落叶林的生长和成熟，将研究白粘土溪内的物理环境（例如水温、溪流中的光可用性）、水生生物群落（例如物种组成、营养动态）以及营养物的命运的变化顺序。该项目将以对河流恢复的长期研究为基础，增加我们对恢复后生态变化的基本了解，并为负责实施恢复工作的资源管理者提供信息。其他更广泛的影响将包括为宾夕法尼亚州东南部和特拉华州北部的教师举办为期一周的研讨会，向他们介绍白土溪的研究。 初中和高中教师将接受长期环境数据使用方面的培训，提高他们利用生态数据的能力，增强学生的数学技能、分析能力、环境知识和对科学本质的理解。
