Tree Inventory Data Of Pinus Nigra J.F.Arnold Subsp. Calabrica (Poir.) Maire In Southern Italy

The dataset supplied in this article provides data from a stand of <em>Pinus nigra </em>J.F.Arnold<em> </em>subsp.<em> calabrica</em> (Poir.)<em> </em>Maire (Calabrian black pine) characterized by old trees, with a relevant role for forest community biodiversity. Natural stands of Calabrian black pine have both outstanding conservation and cultural values, to be taken under consideration in forest and land uses management and monitoring plans. A time series of dendrometric parameters is provided for 58 pine trees: the data were collected during three forest surveys (in 1976, 1986 and 2016). These data, in combination with other forest stand and environmental parameters, may effectively contribute to understand the dynamics of Calabrian black pine forests in southern Italy, thus how the natural and human disturbances have affected the structure and species composition of these forest ecosystems with high ecological value.本文所提供的数据集来源于一片卡拉布里亚黑松（*Pinus nigra* J.F.Arnold subsp. *calabrica* (Poir.) Maire）林分，该林分以老龄林木为特征，对森林群落生物多样性具有重要作用。卡拉布里亚黑松天然林分兼具突出的保护价值与文化价值，需在森林与土地利用管理及监测规划中予以考量。 本数据集为58株黑松提供了测树参数时间序列，数据采集于1976年、1986年及2016年开展的三次森林调查。该数据集结合其他林分与环境参数，可有效助力解析意大利南部卡拉布里亚黑松林的动态变化，进而阐明自然与人为干扰如何影响这类具有高生态价值的森林生态系统的结构与物种组成。
