Herziening van de indeling in ecologische soortengroepen voor Nederland en Vlaanderen

摘要

In 1987 a first version of the ecological species groups for the Netherlands was published. The groups indicate which plant species occur on different site types. For the characterisation of the sites an ecotope classification is used in which sites on the scale level of ecotopes are classified using vegetation structure and site conditions as classification characteristics. A revision was considered necessary in order to bring the species groups up to date with current knowledge on the relationshipsbetween plant species and site conditions, and to extend the area in which the species groups can be used by including Flanders. Prior to the revision the validity of old species groups was extensively tested on the basis of releve's, literature and expert knowledge. The resulting species groups will be published in the forthcoming standard list of the Dutch flora. Details on the revision and the resulting species groups can be found on the following web site: http://www, synbiosys.alterra.nl/ecotopen.
