Description (English)

Temporary lakes principally filled by subterranean waters and particular to karstic limestone areas in Ireland. Most flood in the autumn and then dry up between April and July. However, some may flood at any time of the year after heavy rainfall and dry out again in a few days; others, close to the sea, may be affected by the tide in summer. These lakes fill and empty at particular places. The soils are quite variable, including limestone bedrock, marls, peat, clay and humus, while aquatic conditions range from ultra oligotrophic to eutrophic. The vegetation mainly belongs to the alliance Lolio Potentillion anserinae Tx. 1947, but also Caricion davallianae Klika 1934.

Conservation status

EU conservation status

Conservation status assesses every six years and for each biogeographical region the condition of habitats and species compared to the favourable status as described in the Habitats Directive. The map shows the 2013-2018 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.

Good: A habitat is in a situation where it is prospering and with good prospects to do so in the future as well
Poor: A habitat is in a situation where a change in management or policy is required to return the habitat to favourable status but there is no danger of disappearance in the foreseeable future
Bad: A habitat is in serious danger of disappearing (at least regionally)
Unknown: The information available for the habitat type is scarce and does not allow a proper assessment of its conservation status
