The newly established collaborative vegetation-plot database GrassPlot (Database of Scale-Dependent Phytodiversity Patterns in Palaearctic Grasslands; GIVD code: EU-00-003) is seeking high-quality vegetation-plot records from any type of grassland sensu lato (mesic, wet, dry, coastal, alpine, saline, rocky, fen) from the whole Palaearctic biogeographic realm (Europe, North Africa, West, Central and North Asia). Current data coverage is available at https://www.bayceer.uni-bayreuth.de/ecoinformatics/en/grassplot/gru/html.php?id_obj=140121, indicating that we specifically search for data from Western Europe (France, Benelux, United Kingdom, Ireland), the Mediterranean Basin as well as Japan and Korea. However, high-quality data from other parts of the Palaearctic are also welcome.

To be accepted, plots must have been precisely delimited in the field (i.e. with pins in the corners and line around the edges) and sampled carefully and exhaustively for complete species list. They either can come from one or several of the GrassPlot standard grain sizes (0.0001; 0.001; 0.01; 0.1; 1; 10; 100; 1000 m²) or be nested-plot series with at least 4 grain sizes. Preferentially, we take plots on which also the bryophytes and lichens have been recorded and that have environmental data (e.g. soil data) measured in the plot.

Those who have such data and agree with the GrassPlot Bylaws (https://www.researchgate.net/publication/315382229) can join the GrassPlot Consortium, meaning that they will be invited for active co-authorship when papers are emerging that use their data and they can also get access to the GrassPlot database for own projects according to the Bylaws.

If you wish to contribute to GrassPlot, have questions or know of published sources with such data, please let the GrassPlot database manager Idoia Biurrun ([email protected]) or me ([email protected]) know.

[If you have traditional phytosociological data of Palaearctic grasslands that do not meet the strict quality criteria of GrassPlot (e.g. have not been delimited precisely in the field or do not have GPS coordinates) they might still be very valuable for "normal" vegetation-plot databases. You are thus invited to contribute them instead/additionally to member databases of the European Vegetation Archive (EVA) or the global plot database "sPlot". There are various EDGG-related, collaborative grassland databases for many European countries (see "Vegetation databases" at https://www.bayceer.uni-bayreuth.de/ecoinformatics/?lang=en). Names and contact data of all other EVA databases are available at: http://euroveg.org/eva-database-participating-databases.]
