We analyse environments undergoing temporary and permanent waterlogging in central-western Spain. Their high phytocenotic diversity is conditioned by the moisture gradient. In small areas with temporary waterlogging of an ephemeral nature there is a predominance of Habitat 3170* (temporary Mediterranean lakes and pools), represented by the following associations: Pulicario uliginosae-Agrostietum salmanticae; Junco pygmaei-Isoetetum velati; Hyperico humifusi-Cicendietum filiformis; Periballio laevis-Illecebretum verticillati; Sibthorpio-Pinguiculetum lusitanicae. If the waterlogging persists for longer periods, and only the upper soil horizon dries out, the dominant communities belong to Habitat 6410 (meadows with Molinia caerulea on moist soils most of the year). This is a non-priority habitat for the EU, which we propose should be made priority due to its transitional character between 3170* and 4020*.

Permanently waterlogged areas are home to communities of Genistion micrantho-anglicae (Rivas-Martínez, 1079), with the presence of habitat 4020* in this alliance, and including the association Erico tetralicis-Myricetum gale, and on its outer edges on less waterlogged soils, a community of Erica lusitánica, and outside this a community of Erica scoparia.

Abstract
We analyse environments undergoing temporary and permanent waterlogging in central-western Spain. Their high phytocenotic diversity is conditioned by the moisture gradient. In small areas with temporary waterlogging of an ephemeral nature there is a predominance of Habitat 3170* (temporary Mediterranean lakes and pools), represented by the following associations: Pulicario uliginosae-Agrostietum salmanticae; Junco pygmaei-Isoetetum velati; Hyperico humifusi-Cicendietum filiformis; Periballio laevis-Illecebretum verticillati; Sibthorpio-Pinguiculetum lusitanicae. If the waterlogging persists for longer periods, and only the upper soil horizon dries out, the dominant communities belong to Habitat 6410 (meadows with Molinia caerulea on moist soils most of the year). This is a non-priority habitat for the EU, which we propose should be made priority due to its transitional character between 3170* and 4020*. These communities belong to the associations Hyperico undulati-Juncetum acutiflori and Lobelio urentis-Lotetum pedunculati. Permanently waterlogged areas are home to communities of Genistion micrantho-anglicae (Rivas-Martínez, 1079), with the presence of habitat 4020* in this alliance, and including the association Erico tetralicis-Myricetum gale, and on its outer edges on less waterlogged soils, a community of Erica lusitánica, and outside this a community of Erica scoparia.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
