Tree census data from secondary subtropical forests invaded by Ligustrum lucidum, Horco Molle, Argentina, 2020-2023

The data resource consists of tree census data and shapefiles about plots established on invaded sub-tropical mountain secondary forests (Yungas) in the Horco Molle experimental reserve and Parque Sierra de San Javier (Horco Molle), Tucumán, Argentina. An experiment was conducted to investigate management control of the invasion of nonnative species Ligustrum to restore native tree diversity from June 2020 to November 2023. The data includes the census of 6 plots (240 metres by 140 metres, 3.36 hectares for each plot, the location specified in the shapefile), with arbitrary coordinates (x for the longest side and y for the shortest) to assess the location of each tree. For each tree stem, a tagged ID was assigned and the species recorded, the presence of secondary stems, its perimeter at breast height, the number of small stems, the number of death stems, stem shape and stem fusion.

该数据资源包含关于阿根廷图库曼省霍尔科莫莱实验保护区和圣胡韦尔·德·桑哈维拉（霍尔科莫莱）次生热带山地森林（云杉）上建立的样地及其地形图的树木普查数据。自2020年6月至2023年11月，进行了一项实验，旨在研究非本地物种女贞（Ligustrum）入侵的管理控制措施，以恢复本地树木多样性。数据包括6个样地（每个样地长240米、宽140米，面积为3.36公顷，位置由地形图指定）的普查信息，采用任意坐标（x轴代表最长边，y轴代表最短边）以评估每棵树的位置。对于每棵树干，分配了一个带有标签的ID，并记录了树种、是否存在次生茎、胸高处的树干周长、小茎数量、死亡茎数量、树干形状和树干融合情况。
