Secondary successional ecosystems are widespread across the southeastern US and, as a whole, comprise a substantial sink for atmospheric carbon dioxide. Despite the important role of successional ecosystems in carbon cycling and other ecological processes, considerable uncertainty remains concerning the spatial and temporal dynamics of these ecosystems. With this in mind, the principle goal of this project is to understand the status of and controls on successional ecosystems in the southeastern US through development and analysis of coupled remotely sensed and ground based data. The project will use new and existing datasets to evaluate successional characteristics and ecological processes within and among five separate landscapes in North Carolina. This work will lay the framework for future research on carbon cycling, hydrological process, and climate-vegetation feedbacks within this region and other regions where secondary ecosystem succession is an important landscape-scale process. This work also seeks to broaden participation of underrepresented students in ecological sciences by collaborating with the Ecological Society of America's Strategies for Ecology Education, Development and Sustainability (SEEDS) program to recruit undergraduate students from minority-serving and other institutions to participate in training, fieldwork, and numerical analysis related to secondary ecosystem succession.

次要继承生态系统在整个美国东南部都广泛，总体上是大气二氧化碳的大量水槽。尽管继承生态系统在碳循环和其他生态过程中的重要作用，但与这些生态系统的空间和时间动态有关的不确定性仍然存在。 考虑到这一点，该项目的主要目标是通过开发和分析远程感知和基于地面的数据来了解美国东南部的继承生态系统的状态和控制。该项目将使用新的和现有的数据集评估北卡罗来纳州五个单独的景观内外的演讲特征和生态过程。 这项工作将为未来关于碳循环，水文过程和气候蔬菜反馈的研究奠定框架，以及次生生态系统演替是重要的景观规模过程的其他地区。 这项工作还旨在通过与美国生态学会的生态学教育，发展和可持续性（SEEDS）计划合作，扩大代表性不足的学生参与生态科学科学，以招募与少数群体服务和其他机构一起参与培训，现场工作，以及与二级生态系统相关的数字分析的本科生。
