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.
