Centenary forest statistics informing major attributes of French forests were digitized, checked for consistency, and used to infer forest dynamics. Comparison to forest inventory data highlights increases in forest area and tree diversity, and substantial maturation of forests. Dataset access at10.5281/zenodo.3739458 The history of European forest dynamic remains fragmental. In France, the Daubrée statistics (1908) and agricultural statistics (1892, 1929) formed fundamental material to fill this gap. Release, test, and summarize the digitalized dataset. Analyze long-term forest changes in forest area, composition, and structure. Primary data on forest area across NUTS-3 geographic units, split by forest management and ownership categories and dominating tree species (Daubrée), were digitized and cross-compared. Centennial changes in forest attributes were assessed from modern forest inventory data. Cross-comparison revealed: (1) strong temporal consistency in forest changes over time, (2) systematic and interpretable biases in ownership/management categories between Daubrée and agricultural statistics. Strong shift from coppices to high forests, increased prevalence of private ownership, and constant proportion of broadleaf- and conifer-dominated forests were highlighted, with increased tree species diversity at country scale. Ancient statistics are shown to play a major role in retrospective land-use and forest policy analysis.

古代森林统计数据提供了对法国森林面积现状和动态的百年视角

将告知法国森林主要属性的百年森林统计数据进行数字化、检查一致性并用于推断森林动态。与森林清单数据的比较突出显示了森林面积和树木多样性的增加,以及森林的实质性成熟。数据集访问 at10.5281/zenodo.3739458 欧洲森林动态的历史仍然不完整。在法国,Daubrée 统计数据(1908 年)和农业统计数据(1892 年、1929 年)形成了填补这一空白的基本资料。发布、测试和汇总数字化数据集。分析森林面积、组成和结构的长期森林变化。按森林管理和所有权类别以及主要树种 (Daubrée) 划分的 NUTS-3 地理单位森林面积的主要数据进行了数字化和交叉比较。根据现代森林清单数据评估了森林属性的百年变化。交叉比较显示:(1) 森林随时间变化的强烈时间一致性,(2) Daubrée 和农业统计数据之间所有权/管理类别的系统性和可解释性偏差。强调了从林地向高地森林的强烈转变、私人所有权的增加以及阔叶和针叶林占主导地位的森林比例不变,以及国家范围内树种多样性的增加。古代统计数据在回顾性土地利用和森林政策分析中发挥着重要作用。(2) Daubrée 和农业统计数据之间所有权/管理类别的系统性和可解释性偏差。强调了从林地向高地森林的强烈转变、私人所有权的增加以及阔叶和针叶林占主导地位的森林比例不变,以及国家范围内树种多样性的增加。古代统计数据在回顾性土地利用和森林政策分析中发挥着重要作用。(2) Daubrée 和农业统计数据之间所有权/管理类别的系统性和可解释性偏差。强调了从林地向高地森林的强烈转变、私人所有权的增加以及阔叶和针叶林占主导地位的森林比例不变,以及国家范围内树种多样性的增加。古代统计数据在回顾性土地利用和森林政策分析中发挥着重要作用。
