mariarose.evesdown@inbo.be 0009-0000-9611-3824 2026-07-23 eng This dataset was gathered by INBO as part of a 1995 vegetation inventory in the Bourgoyen-Ossemeersen nature reserve. Certain abiotic data was also collected, but is not presented here. All observations and identifications were made by trained experts. The data comes from INBOVEG, the INBO vegetation record database (also part of the "Global Index of Vegetation-plot databases" and the "European Vegetation Archive"). The GBIF dataset is the same as the data in INBOVeg. The relevant identification code is 'IV2014072211590684'. It has been previously published on GBIF as part of the FLORABANK1 bulk data publication (https://doi.org/10.3897/phytokeys.12.2849) at either a 1 km² or a 4 km² scale; here, it is published with specific locations (with 30m² uncertainty). No coordinate uncertainty was noted in the accompanying report, so 30m² is only an estimate. The coordinates were originally recorded in the Belgian Lambert system, but they are given here as WGS84 coordinates.In the data, under 'Occurrence remarks', the vegetation layer is noted. Details of the sampling protocol, including the vegetation layer codes, are given in the associated report: Butaye, J., De Becker, P. & Maelfait, J.-P. (1995).

(Rapporten van het instituut voor natuurbehoud; no. 23)This research was carried out by INBO under its previous name (the Institute for Nature Conservation, in Dutch ‘het Instituut voor Natuurbehoud’), on behalf of the City of Ghent. Much of the nature reserve was previously working agricultural grasslands which were taken out of agricultural service in 1974, some 30 years before these vegetation surveys were carried out.To allow anyone to use this dataset, we have released the data to the public domain under a Creative Commons Attribution waiver (https://creativecommons.org/licenses/by/4.0/).

Due to the limited surveying period, it is assumed that certain vegetation was missed and the surveys therefore do not present an entire view of the vegetation present in the nature reserve during that year. 3 m x 3 m test areas/plots were fully surveyed, with all contained species being noted and their abundance estimated using the Londo scale. Below 5%, the symbols 'r' (raro = 1-3 exemplaars), 'p' (paululum = 3-20 exemplaars), 'a' (amplius = 20-100 exemplaren) or 'm'm (multum = >100 exemplaars) were used. The used Londo scale is given in the accompanying report (page 12, Butaye, J., De Becker, P. & Maelfait, J.-P., 1995). All observations and identifications were made by trained experts. It was difficult to distinguish Myosotis laxa spp. cespitosa, which was instead classified as Myosotis sp. The different types of Agrostis grasses were also generally grouped together, with the exception of certain flowering Agrostis canina individuals which were clearly identifiable. Piet De Becker principalInvestigator J Butaye principalInvestigator J-P Maelfait principalInvestigator At the request of the City of Ghent, a vegetation map of the ‘Bourgoyen-Ossemeersen’ nature reserve was drawn up during the 1995 growing season. A thorough inventory and interpretation of both biotic and abiotic parameters was essential for understanding the relationships and developments within a given ecosystem, and was indispensable for developing a scientifically sound ecological management plan. Furthermore, a baseline condition was needed in order to evaluate the management measures implemented. This vegetation study aimed to shed more light on the evolution of the various vegetation types. From both a botanical and vegetation science perspective and from the point of view of (avi-)fauna conservation, effective vegetation management is the only way to ensure that the area retains its ecological value in the long term as a wintering ground for waterbirds and as a typical East Flemish floodplain and valley grassland area. In an initial phase, around three hundred representative vegetation surveys were carried out. In these surveys, all species within an area of 3 by 3 metres were recorded, together with an estimate of their cover and abundance using Londo’s scale. The raw data was then classified using the Fortran programme TWINSPAN (Hill, 1979) to produce a typology, which formed the basis for an area-wide vegetation map. A brief literature review also provided an overview of the various vegetation types and their habitats. Together with knowledge regarding management, soil, history and topography, this serves as source material for the explanatory text. A comparative study was then carried out using a previously produced vegetation map from 1982. Since the water level maintained at the time of the assessment of the distribution and potential spread of the vegetation types was a determining factor, a detailed topographical survey of the entire study area was also carried out. Using geostatistical techniques, these measurements were interpolated across the entire study area in order to produce a contour map. The City of Ghent funded this research.
