A synopsis of bryophyte-lichen syntaxa in the Netherlands

Abstract

We present a first complete overview of the bryophyte-lichen syntaxa in the Netherlands, including diagnostic species and Red List status of vegetations representing each (sub)association. The classification is based on more than 5000 Dutch vegetation relevés, the majority recorded after the year 2000. Whenever appropriate, we integrated bryophyte and lichen syntaxonomy. The Dutch list of bryolichenosociological units consists of 168 syntaxa: 16 classes, 27 orders, 37 alliances, 82 associations and 6 subassociations. We present synoptic tables of 13 newly described syntaxa: two alliances, nine associations and two subassociations. Finally, we present ranges of the abiotic habitat variables moisture, light availabilty, nutrient richness and acidity on class level, based on estimated values of diagnostic species of individual associations in each class.
