Earthworms are key organisms in terrestrial ecosystems. They are found globally and provide significant ecological functions and ecosystem services, so their conservation should be a priority. Yet little is known about the large-scale impacts of global change on earthworm diversity, species distribution, and assemblage structure. More importantly, there are no comprehensive data on changes over long periods of time. In the 1960s, Marcel Bouché conducted a study by sampling earthworm assemblages in 1399 locations in mainland France, including the island of Corsica. Through the #Vers2022 project, we achieved the resampling of 418 of these historical sites, creating the first dataset to assess the long-term changes in earthworm assemblages at a large scale. This dataset includes Bouché (1972) assemblage data, with original taxon's names, absence data, and site descriptions, published in 1972 in French, which were still not freely accessible in a standardized, computerized format. It consists of 36,079 individual earthworm records from 1399 sites, documenting 127 species and subspecies between 1961 and 1970. Additionally, it provides the results of the #Vers2022 resurvey, which includes 11,137 individual records (22,344 including unidentified) from 418 resampled sites, documenting 122 species and subspecies between 2019 and 2023. We followed the framework of quasi-permanent plots, ensuring that the environment was as similar as possible between the historical sampling and its current resampling. These sites were sampled using a standardized, reproducible, and quantitative protocol, unlike the historical sampling, which was qualitative. The dataset also includes information on the individual body mass of each specimen, the total earthworm biomass of each assemblage, and soil analysis data. Furthermore, this work presents the updated taxonomy of each taxon provided by Bouché, along with an assessment of each species name in view of current taxonomy, as well as proposed names for future studies utilizing these data. The #Vers2022 dataset represents a significant improvement in our understanding of French earthworm diversity and can be used to assess changes in diversity and assemblages over a span of more than 50 years, including patterns in individual body mass.

蚯蚓是陆地生态系统中的关键生物。它们分布于全球，发挥着重要的生态功能并提供生态系统服务，因此对它们的保护应成为优先事项。然而，关于全球变化对蚯蚓多样性、物种分布和群落结构的大规模影响，我们所知甚少。更重要的是，缺乏关于长期变化的全面数据。20世纪60年代，马塞尔·布歇在法国大陆（包括科西嘉岛）的1399个地点对蚯蚓群落进行了采样研究。通过#Vers2022项目，我们对其中418个历史地点进行了重新采样，创建了首个用于大规模评估蚯蚓群落长期变化的数据集。该数据集包括布歇（1972年）的群落数据，带有原始分类单元名称、缺失数据和地点描述，这些数据于1972年用法语发表，目前仍无法以标准化的计算机格式免费获取。它包含来自1399个地点的36079条蚯蚓个体记录，记录了1961年至1970年间的127个物种和亚种。此外，它还提供了#Vers2022重新调查的结果，其中包括来自418个重新采样地点的11137条个体记录（包括未鉴定的个体在内共22344条），记录了2019年至2023年间的122个物种和亚种。我们遵循准永久性样地的框架，确保历史采样及其当前重新采样之间的环境尽可能相似。这些地点采用标准化、可重复且定量的方案进行采样，与历史采样的定性方式不同。该数据集还包括每个标本的个体体重信息、每个群落的蚯蚓总生物量以及土壤分析数据。此外，这项工作展示了布歇提供的每个分类单元的更新分类法，以及根据当前分类法对每个物种名称的评估，还有为利用这些数据进行未来研究而提议的名称。#Vers2022数据集极大地增进了我们对法国蚯蚓多样性的理解，可用于评估50多年间多样性和群落的变化，包括个体体重模式。这些数据根据知识共享署名 - 非商业性使用 - 相同方式共享许可协议发布。
