Mediterranean humid herb communities dominated by rushes (Scirpus holoschoenus) and tall grasses, common in depressions with wet soils, on both siliceous and calcareous terrain. The water table remains permanently near to the surface but is subject to strong seasonal fluctuations, experiencing a lower level during summer and a higher in the rainy season, although the habitat is never or very rarely flooded. It is more frequent in areas under a predominantly stock-rearing system, being thus more abundant in siliceous regions. It is widespread in the entire Mediterranean basin, extending as far as the coasts of the Black Sea and the Balkans, north to Romania. This habitat has been traditionally grazed in the areas where summer pastures dry out and cattle and sheep have to graze humid pastures in the dry season. However, it is not dependent on grazing and its sustainability can be assured without this intervention.

Indicators of good quality:

  • Domination by a complete and dense cover of reeds (Scirpus holoschoenus) and grasses

  • High plant species diversity

  • Absence of shrubs, particularly willows, ashes or poplars, indicating initial stages of succession towards forest

  • No signs of heavy grazing.

Threat status

Synthesis of Red List assessment

The small amount of available quantitative data supports an evaluation of Least Concern (LC), despite a continuing decline in quantity and quality and of several threats the habitat faces.

Red List of habitat categories and criteria descriptions

Pressures and threats

  • Agriculture
    • Modification of cultivation practices
    • Grassland removal for arable land
    • Grazing
    • Abandonment of pastoral systems, lack of grazing
  • Urbanisation, residential and commercial development
    • Urbanised areas, human habitation
  • Pollution
    • Pollution to surface waters (limnic, terrestrial, marine & brackish)
  • Natural System modifications
    • Human induced changes in hydraulic conditions

Habitat restoration potential

Recovery depends greatly on the feasibility of restoring the distinctive hydrological conditions.

For each habitat a distribution map was produced from a wide variety of sources indicating known and potential occurrences of the habitat in 10x10 km grids within Europe. Occurrences in grid cells were given in two classes: actual distribution from relatively reliable sources (surveys, expert knowledge), and potential distribution based on models or less reliable indicators. Please download the fact sheet to see the map.

AOO = the area occupied by a habitat measured in number of 10x10 km grid cells.
EOO = the area (km2) of the envelope around all occurrences of a habitat (calculated by a minimum convex polygon).
