Non-native plant species are an ever-present part of forests today and often negatively influences their adopted natural habitat by reducing survival of native plant and animal species. The present study will investigate the impact of Amur honeysuckle, an invasive non-native shrub, on the forests of Southwestern Ohio. The research will focus on nutrient cycling within this ecosystem by examining the relationship between organic inputs (e.g., fallen leaves), soil nutrients, and soil microbial diversity and composition (bacteria and fungi). These parameters strongly influence how fast nutrients are cycled through an ecosystem and may be an important predictor of what species will be most successful in an area. The study will elucidate differences between forested sites with and without honeysuckle and examine the potential for and time-scale of recovery of below-ground resources through honeysuckle removal experiments.The results of this research will provide new insights that may enhance forest restoration efforts. By integrating research and education the project will enhance undergraduate education through hands on research experiences and encourage broader participation by underrepresented groups in the sciences. To achieve these goals the project will, create summer research positions for college students from underrepresented groups, develop an exciting inquiry based laboratory that will introduce students to forest ecology through engaging them in actual field research, and conduct short-term summer classes for K-12 students from local public schools.

非本土植物物种是当今森林中无处不在的一部分，往往会减少本土动植物物种的生存，从而对它们所采用的自然栖息地产生负面影响。本研究将调查外来入侵灌木阿穆尔金银花对俄亥俄州西南部森林的影响。这项研究将通过研究有机输入(例如落叶)、土壤养分和土壤微生物多样性和组成(细菌和真菌)之间的关系，重点研究该生态系统内的养分循环。这些参数强烈地影响着营养物质在生态系统中循环的速度，并可能是一个重要的预测指标，可以预测哪个物种将在一个地区最成功。这项研究将阐明有无金银花的林地之间的差异，并通过去除金银花的实验来检验地下资源恢复的潜力和时间尺度。这项研究的结果将提供新的见解，可能会加强森林恢复工作。通过将研究与教育相结合，该项目将通过实践研究经验来加强本科教育，并鼓励未被充分代表的群体更广泛地参与科学领域。为了实现这些目标，该项目将为来自代表性不足群体的大学生创造暑期研究职位，开发一个令人兴奋的基于探究的实验室，通过让学生参与实际的实地研究来向他们介绍森林生态学，并为当地公立学校的K-12学生举办短期暑期班。
