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

[This dataset is embargoed until November 10, 2025]. 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. The work was carried out as part of NERC grant NE/S011641/1 Optimising the long-term management of invasive species affecting biodiversity and the rural economy using adaptive management Full details about this dataset can be found at https://doi.org/10.5285/c3295206-052a-4c87-911a-75d357791b5c

本数据集将于2025年11月10日解禁。数据资源包括关于阿根廷图库曼省Horco Molle实验保护区和Parque Sierra de San Javier（Horco Molle）所设立的入侵性次生热带山地森林（Yungas）样地树种的普查数据和形状文件。自2020年6月至2023年11月，开展了一项实验，旨在研究非本土物种女贞（Ligustrum）入侵的管理控制措施，以恢复本土树种多样性。数据包括6个样地（每个样地240米×140米，面积3.36公顷，位置由形状文件指定）的普查，以及用于评估每棵树位置的任意坐标（x为最长边，y为最短边）。对于每棵树干，分配了一个带有标签的ID，并记录了树种的名称、是否存在次生茎、胸高处的树干周长、小茎的数量、死亡茎的数量、树干形状和树干融合情况。该研究作为NERC资助项目NE/S011641/1“利用适应性管理优化影响生物多样性和农村经济的长久期入侵物种管理”的一部分进行。有关本数据集的详细信息，请参阅https://doi.org/10.5285/c3295206-052a-4c87-911a-75d357791b5c。
