Long-term plant invasion in disturbed and undisturbed forests: species richness, frequency, and abundance

This data publication contains understory vegetation measured on 23 80+ years of age mature second-growth stands and 12 15-year old clearcut stands on the Cheat Ranger District of the Monongahela National Forest, West Virginia, USA. These data were sampled every 5-6 years from 2001-2017 (for mature stands) and 2002-2018 for clearcut stands. Stands were randomly selected but stratified across three land types that followed a moisture gradient. Data include plant species cover for both native and invasive nonnative plants in 2002 and 2018, as well as stand-level measurements of frequency and cover of invasive plant species measured multiple times between 2001 and 2018.
The purpose of this study was to determine how invasive and native plant species interact in response to changing environmental conditions and disturbances. This study is one of several studies to examine the effects of invasive plants on forest ecosystems and how best to ameliorate their impacts.

本数据集收录了美国西弗吉尼亚州莫农加希拉国家森林奇特特护林区内的林下植被调查数据，调查对象涵盖23个80年以上树龄的成熟次生林分，以及12个15年生的皆伐迹地林分。其中，成熟林分的采样时间跨度为2001年至2017年，皆伐迹地林分的采样时间跨度为2002年至2018年，两次采样间隔为5至6年。林分采用随机抽样方法选取，并按水分梯度划分为三类土地类型进行分层抽样。数据集涵盖2002年与2018年时本土植物与外来入侵植物的物种盖度数据，同时包含2001年至2018年间多次测定的林分尺度入侵植物频度与盖度测量结果。
本研究旨在探明本土植物与入侵植物如何响应环境变化与干扰过程并产生种间互作关系。本研究是系列研究之一，旨在探究入侵植物对森林生态系统的影响，以及制定最优的入侵影响缓解策略。
