| The ecological groups (appendix 3 and 4) are defined by biotic and abiotic characteristics, in such a way that the assignment of plant species to ecological groups can be verified by means of direct measurements of the (a)biotic characteristics used. A difference with former subdivisions¹² is the fact that a species can be assigned to more than one ecological group, depending on the ecological amplitudo of the species. The (a)biotic characteristics used are vegetation structure and stage of succession, salinity, substratum, moisture regime, nutrient availability, acidity, dynamics of the ecosystem (sand drift, trampling etc.). Each characteristic has been subdivided in several classes (appendix 1). Combinations of these classes are used to define different... |

| 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 relationships between 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 relevé’s, literature and expert... |

| The present Standard List is the updated sixth edition in the series ‘Standard List of the Flora of the Netherlands’. Standard Lists have regularly been published since 1971 with intervals of 4 to 8 years and give an up-to-date survey of the vascular plant species occurring in the Netherlands. The present Standard List gives for each species: (1) the taxon code number, (2) the scientific name, (3) the vernacular name in Dutch, (4) the rarity for three periods in the 20th century according to the KFK-scale, (5) the Red List category to which it belongs, (6, 7) the origin and – relevant for non-indigenous species – the period of naturalization, (8, 9) the dispersal and seed bank categories to which it belongs, and (10, 11) the ecological species groups to... |
