Summary

This habitat includes helophytes beds developing in inland saline or brackish lakes, ponds and other standing or slowly flowing waters (such as saline Mediterranean rivers) subjected to dry out during summer. The habitat may include, depending by the hydrological regime, emergent communities dominated by species tolerant to brackish or saline conditions such as Bolboschoenus maritimus, Typha laxmannii, Typha domingensis, Phragmites australis, Schoenoplectus tabernaemontani, Schoenoplectus triqueter, or communities dominated by tall rushes, such as Juncus maritimus, Juncus acutus and Juncus subulatus. The communities are species-poor and often mono-dominant. Similar communities in dune slacks are considered part of habitats B1.8a or B1.8b.

In warmer and continental parts of Europe, during the hot summer, the water level in the wetlands may decrease and the water may even completely disappear. Several species inhabiting this habitat, especially reed, may survive even under such hypersaline conditions. Bolboschoenus maritimus is the most widespread middle tall helophyte on the water margins of wetlands with different levels of salinity, growing in a range from freshwater to hypersaline water. These communities mainly inhabit the water fringes, but when a wetland dries out during the year, they may expand and cover the whole bottom of a lake or pond.

This habitat is typically in contact with the habitats C1.5 (Permanent inland saline and brackish waters), C3.5 (Periodically exposed saline shores with pioneer and ephemeral vegetation) and E6 (inland salt steppes). It is distributed in the arid continental and Mediterranean parts of Europe.

Indicators of quality:

  • Minimum salinity around 0.5 ‰
  • Natural high electrical conductivity of the water
  • No alteration of the natural salinity range
  • Dominance of halophytic emergent species rather than freshwater emergent species
  • Absence of overgrowing with shrubs and trees
  • No signs of eutrophication and dominance of ruderal species
  • No indicator of negative anthropogenic influence (e.g. regulation of the water level, chemical pollution)

Threat status

Synthesis of Red List assessment

Saline reedbeds qualify as Endangered (EN) due to a very large historical decline in quantity (72%) based on estimations from three EU28 and one addiitonal EU28+ countries. Although the number of countries is low, the analysed area is still more than 50% of the present area. The most severe historical decline took place in Hungary (-90%) and the Czech Republic (-98%). These values overrule a strong historical increase in Austria.

Pressures and threats

  • Agriculture
    • Cultivation
    • Grazing
    • Abandonment of pastoral systems, lack of grazing
    • Irrigation
  • Natural System modifications
    • Human induced changes in hydraulic conditions
    • Landfill, land reclamation and drying out, general
    • Canalisation & water deviation
    • Flooding modifications

    • Modification of standing water bodies
    • Saltwater intrusion of groundwater
    • Other human induced changes in hydraulic conditions
  • Climate change
    • Droughts and less precipitations

Habitat restoration potential

Yes, if adequate water levels/hydroperiods or shores can be restored. Pending on the situation, this can be done through indirect intervention (eg improving catchment area functionality) or naturally (by stopping water input).

Conservation and management needs

Avoid input of freshwater that would modify water (soil) salinity and prevent seasonal dry periods. Avoid embankment, modification of cathment area or water derivation that would result in absence of flooding (which can be corrected by water input in some areas). From a broader nature conservation point-of-view tall helophytes may form a threat to more endangered saline or brackish grasslands. Therefore extensive grazing should be promoted where tall helophytes are at risk of expansion.

    • Restoring/Improving the hydrological regime

Distribution

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.
