The objective of this study was to evaluate vegetation recovery on footpaths in woodland that have been closed for access for 6 years. A vegetation survey was conducted in four mesophile forests, in transects perpendicular to the trail. Analyses concentrated on the direction and rate of the recovery process. Vegetation on trail sides in these ecosystems recovered substantially. Non-metric multidimensional scaling based upon species composition separated the four sample locations and each cluster contained representatives of the three major trail zones: path centre, transition and undisturbed zones. Analysis of distribution of life forms, plant strategies and seedbank longevity indices showed no differences between trail zones. This indicates that vegetation on the path centre is likely to recover towards the plant composition of the undisturbed zone. Ellenberg values indicate that environmental variation is not related to former path structures, as significant variability was only observed between the forest sites. Furthermore, the analysis concentrated on characteristics of species relevant to the recovery process.
本研究的目的是评估已封闭6年禁止通行的林地人行道上的植被恢复情况。在四个中生森林中,沿着与小径垂直的样带进行了植被调查。分析集中在恢复过程的方向和速率上。这些生态系统中步道两侧的植被有显著恢复。基于物种组成的非度量多维标度法将四个采样地点区分开来,每个聚类都包含三个主要步道区域的代表:路径中心、过渡区和未受干扰区。对生活型分布、植物策略和种子库寿命指数的分析表明,步道区域之间没有差异。这表明路径中心的植被可能会朝着未受干扰区的植物组成恢复。埃伦贝格值表明,环境变化与以前的路径结构无关,因为仅在森林地点之间观察到显著的变异性。此外,分析集中在与恢复过程相关的物种特征上。
