Background The dataset covers wild tracheophytes (native species, naturalised aliens and casuals) of Vladimir Oblast, Russia. It includes only one occurrence per species per grid square, thereby recently confirmed earlier records are not duplicated. Georeferences are based on the WGS84 grid scheme with 342 squares with areas ranging from 94.7 km2 in the northernmost part to 98.2 km2 on the southern boundary (5′ lat. × 10′ long.). Each occurrence is linked to the corresponding grid square centroid, therefore actual coordinates, habitat details and voucher information are unavailable. In late 2011, the earlier version of the dataset was used for the production of grid maps in the standard "Flora of Vladimir Oblast: checklist and atlas". Additional records, obtained during field excursions of 2012 and 2013, were fully included in the "Flora of Vladimir Oblast: grid data analysis". The stable version of the dataset with 123,054 grid records (as of 1867–2013) was published in GBIF in 2017. New information Data obtained in the field during 2014–2020, as well as those extracted from recently published sources, were digitised, structured and finally published in GBIF in April 2021. The last update added 7,000 new grid records. Currently, "Flora of Vladimir Oblast, Russia: an updated grid dataset (1867–2020)" contains 130,054 unique occurrences of 1,465 vascular plant taxa (species, hybrids, species aggregates) from Vladimir Oblast and tiny parts of the adjacent areas. The average number of grid records has grown over the seven years from 363 to 380 species. The grid occurrences are largely based on the field studies by the author, performed during 1999–2020 (121,737 records), as well as on data extracted from the relevant literature, unpublished sources, herbarium collections and citizen science projects (8,317 records). The taxonomic backbone of the occurrence grid dataset follows the accompanying checklist dataset to ensure correct cross-linking of the names. As of April 2021, the dataset on the Vladimir Oblast flora represents the fourth largest dataset on vascular plants of Russia published in GBIF.

俄罗斯弗拉基米尔州的植物群：更新的网格数据集（1867-2020）

背景 该数据集涵盖了俄罗斯弗拉基米尔州的野生气管植物（本地物种、归化外星人和临时工）。它仅包括每个网格正方形每个物种的一次出现，因此最近确认的早期记录没有重复。地理参考基于 WGS84 网格方案，有 342 个方格，面积从最北端的 94.7 平方公里到南边界的 98.2 平方公里（5' 纬度 × 10' 长）。每个事件都与相应的网格正方形质心相关联，因此无法获得实际坐标、栖息地详细信息和凭证信息。2011 年底，早期版本的数据集被用于制作标准“弗拉基米尔州植物群：清单和地图集”中的网格图。在 2012 年和 2013 年实地考察期间获得的其他记录已完全包含在“ 737 条记录），以及从相关文献、未发表来源、植物标本馆收藏和公民科学项目中提取的数据（8,317 条记录）。出现网格数据集的分类主干遵循随附的清单数据集，以确保名称的正确交叉链接。截至 2021 年 4 月，弗拉基米尔州植物群数据集是 GBIF 上发表的俄罗斯维管植物数据集的第四大数据集。
