Alpine pioneer formations of the Caricion bicoloris-atrofuscae

Description (English)

Alpine, peri-Alpine and northern British communities colonising neutral to slightly acid gravelly, sandy, stony, sometimes somewhat argilous or peaty substrates soaked by cold water, in moraines and on edges of springs, rivulets, glacial torrents of the alpine or subalpine levels, or on alluvial sands of pure, cold, slow-flowing rivers and calm backwaters. Permanent or continued soil frost over a long period is essential for the existence of this habitat type. Low vegetation composed principally of species of Carex and Juncus (Caricion bicoloris-atrofuscae).

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 2007-2012 assessments as reported by EU Member State. Assessments are further detailed in the summary document available behind the link below.

Favourable: A habitat is in a situation where it is prospering and with good prospects to do so in the future as well
Unfavourable-Inadequate: 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
Unfavourable-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
