Summary

In this type we have included not only the halo-nitrophilous but also the nitrophilous (with a lower content of salt) communities dominated by perennial plants, often ligneous or hemicriptophytes with large size, frequent in ruderal environments (nearby human dwellings, borders of tracks and ways, etc.) in dry to arid regions in the Mediterranean, Irano-Turanian and North Saharo-Arabian regions. Some botanical groups are highly represented in its flora such as Chenopodiaceae, Artemisia, Santolina and in many areas the grass Lygeum spartum is also abundant. Soluble nitrates and phosphates resulting from organic matter decomposition remain on the soil for long time, due to the scarcity of rainfall. This permits the life of long-living nitrophilous plants, such as shrubs, and thus, the development of a nitrophilous scrub. Such conditions of aridity also favor accumulation of salt in the soils, and many of these formations are adapted to a certain salt tolerance (halo-nitrophilous).

Threat status

Synthesis of Red List assessment

There is no concern about this habitat as it is a ruderal one, strongly linked to human activity. Only some areas in which the endorhoeic basins are being drained for several purposed (transformation into arable land, housing, etc.) report a certain decrease of the subhalophilic variant of the habitat, however with rates of extent and severity that don't meet any threat category.

Conservation and management needs

Preventing from draining the inland wet saline areas (endorheic basins).

List of conservation and management needs

  • Measures related to wetland, freshwater and coastal habitats
    • 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.
