Abstract

A dataset contains 130,054 unique occurrences of 1,465 vascular plant taxa (species, hybrids, aggregates) from Vladimir Oblast (Russia) and tiny parts of adjacent areas. They are largely based on field studies by Alexey P. Seregin performed in 1999–2020 (121,737 records) as well as on data extracted from relevant literature, manuscripts, herbarium collections, and citizen science projects (8,317 records). The most important collections from Vladimir Oblast are deposited in the Moscow University herbarium (MW), the Komarov Institute herbarium in St. Petersburg (LE), and Murom Art Museum.
Georeferences are based on WGS84 grid scheme with 342 squares ranging from 94.7 to 98.2 square km (5.0 minutes lat. × 10.0 minutes long.). Dataset contains only one occurrence per species per grid square, thereby earlier records are not duplicated if they were confirmed recently. Each occurrence is placed in the grid square centroid, therefore real coordinates, habitat details and voucher information are unavailable.
The dataset was used to produce grid maps in the “Flora of Vladimir Oblast: checklist and atlas” (Seregin et al. 2012). Additional records resulted from field excursions of 2012 and 2013 were fully covered in “Flora of Vladimir Oblast: grid data analysis” (Seregin 2014), the second monograph of the series – is an analytical part of the survey with quantitative diversity assessment given.
Data obtained in field in 2014-2020 as well as extracted from recently published souces, were published in April 2021. The last update added 7,000 new records.

Study area descriptions/descriptor: Vladimir Oblast is situated in the centre of East European Plain ca. 100–400 km east ofMoscow. It stretches ca. 190 km from north to south and ca. 290 km from west to east covering 29,084 km2. Mean January temperature is −8.5 °C, mean July temperature is +18.8 °C and mean annual temperature is +4.7 °C (Pogoda i klimat 2013). Mean annual precipitation is 585 mm with the highest precipitation in summer months. Continentality is more pronounced along the eastern border of Vladimir Oblast.
Wet, acid, nutrient-poor soils are peculiar for sandy alluvial and fluvioglacial lowlands. Dry, neutral, nutrientrich soil conditions dominate in agricultural Opolye region and areas along the major rivers (6). Dry, acid, nutrient-poor soils are located in axial zone of a carbonate fold covered by
fluvioglacial sand and sandy loam. Wet, neutral, nutrientrich soils cover Klin-Dmitrov Ridge, the highest upland of Vladimir Oblast reaching 271 m above sea level.
Vladimir Oblast is situated in the ecotone between boreal coniferous and temperate broadleaf forests. Distribution of forest types within the region is clearly determined by soil conditions. Both boreal coniferous forests dominated by Pinus sylvestris and Picea abies on various nutrient-poor substrata and temperate broadleaf forests with Quercus robur, Tilia cordata and Ulmus glabra on loamy eutrophic soils are the main components of original (pre-man) vegetation. Other native plant communities of Vladimir Oblast are peat bogs, xeric meadows on steep slopes and alder stands along lesser streams, as well as meadows, marshes and willow thickets on flood plains. Currently, 29.9 % of land is used for agriculture, while 55 % is covered by forests (official data).
Floristic divisions of Vladimir Oblast are based on UPGMA cluster analysis of grid data (Seregin 2014). This scheme corresponds to some extent to landscape
divisions (Gvozdetsky and Zhuchkova 1963; Seregin 1994).
Balakhna Lowland is the most distinct region with pine forests of Pyrolo–Pinetea class and Oxycocco–Sphagnetea peat bogs. Three spatially separated divisions (Meshchera Lowlands, Nerl district and Lower Oka district) have similar flora and vegetation consisted of Vaccinio–Piceetea boreal coniferous
woods and variable wetland vegetation. In contrast, Oka-Tsna Ridge with similar boreal forests has almost no species from wet habitats due to the proximity of limestone. Klin-Dmitrov Ridge has the most eutrophic conditions and is characterised by Querco–Fagetea and Galio–Urticetea classes, while in the
adjacent Opolye Querco–Fagetea woodlands are enframed by Trifolio–Geranietea sanguinei communities. Gorokhovets Ridge and Oka Plain are covered by Querco–Fagetea woods and xeric meadows with some diagnostic species of Festuco–
Brometea class. Sudogda Upland is the only region where both Querco–Fagetea and Vaccinio–Piceetea communities are equally present.

Study extent description: In 1999–2011, Dr. Seregin have performed grid mapping of vascular plant flora of Vladimir Oblast (Russia). This project used a grid with 339 squares (ca. 100 square km each). Nearly all grid squares were sampled once with an average recording rate 75%. “Flora of Vladimir Oblast: checklist and atlas” (Seregin et al. 2012) have summarized data on 1,371 native and alien species with ca. 118,000 occurrences on distribution maps. This was the first grid atlas published in Russia. In 2012–2013, 48 grid squares were sampled again, and distribution database contains now 123,054 records with 4,823 new records added after printing of “Flora”.
Sampling description: Study of flora begins with the preparation of routes using satellite images. They should link known localities of rare species and areas of potential interest. Our experience suggests that exact route planning helps to avoid delays and fruitless searches. Plants that are difficult to identify in field are collected in herbarium. Previously known localities of rare species are revisited. Track is permanently controlled by GPS.
Quality control description: During the field trip we are recording species in printed spreadsheets with 680 most widely distributed species. This helps us to record common species without occasional misses.
