Summary

The habitat type includes mainly basophilous, xerophytic, tall, tufted, dense or short open grasslands (pseudosteppes) with a wide Mediterranean distribution. They are dominated by plant species which are adapted to the xerothermic climatic conditions, the poor soil conditions and human-made disturbances such as grazing, trampling etc. This habitat type includes several plant communities of dry grasslands, differentiated mostly by the geographical region (western, central or eastern Mediterranean area) and the geological substrate (calcareous, magnesite, dolomite) or the soil types (deep or shallow, sandy, clay or ultramafic soils). Physiognomically, they usually look like steppes even if no Stipa species occur (pseudosteppes). Their floristic composition can be fairly differentiated depending on specific communities, but generally they are dominated by grasses such as Lygeum spartum, Brachypodium retusum, Hyparrhenia hirta, Stipa spp. etc. Alien species, adapted to xerothermic conditions, are often found with high abundance, like Opuntia spp. Grazing or other disturbances, such as wildfires, maintain these grasslands, which are – in several cases – the result of the degradation of forests or evergreen shrublands. Invasion by alien species, transformation to agricultural land and urbanization are the major threats for this habitat type.

Indicators of quality:

This habitat type is characterized by steppe-like grasslands. Subsequently, the most important quality indicators are: (a) dominance of grass species, (b) absence or very low cover of nitrophilous or alien species, (c) no signs of primary succession (e.g. encroachment of chamaephytes or shrub species), (d) presence of properly adjusted, extensive grazing, (e) absence of indications of significant, crevice-like, erosion.

Threat status

Synthesis of Red List assessment

The habitat has been assigned to the category Least Concern (LC) both for EU28 and EU28+. It covers a large area, as it is extended all over the Mediterranean region, and it has only been reduced by 3% in the last decades. As regards reduction in quality, 7% of its area has suffered degradation with a severity of 40%. So, although it cannot be assigned in any category of threat, the application of light conservation measures in the future, such as the maintenance of extensive grazing in many areas and the control of urbanization and disturbances especially in coastal areas and islands should be considered.

Pressures and threats

  • Agriculture
    • Modification of cultivation practices
    • Grassland removal for arable land
    • Abandonment of pastoral systems, lack of grazing
  • Sylviculture, forestry
    • Forest planting on open ground
  • Urbanisation, residential and commercial development
    • Urbanised areas, human habitation
  • Natural biotic and abiotic processes (without catastrophes)
    • Species composition change (succession)

Habitat restoration potential

These grasslands grow on many types of soils, but as they occur in dry climates, their degradation is often caused by soil erosion and thus their restoration may need very long time, depending on the degree of erosion. If the habitat degradation is due to management abandonment and the consequent shrub encroachment, it can be restored by the re-introduction of traditional forms of extensive grazing.

Conservation and management needs

The maintenance of traditional silvopastoral systems is very important for the conservation of this habitat. Extensive grazing is a basic feature of these systems, and management practices should focus on this key factor. In regions where these grasslands are more endangered their change to arable lands and tree plantations should be minimized.

List of conservation and management needs

  • Measures related to agriculture and open habitats
    • Maintaining grasslands and other open habitats
  • Measures related to spatial planning
    • Establish protected areas/sites
    • Legal protection of habitats and species
    • Manage landscape features

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.
