It includes dry and mesic grasslands listed in Annex I of the Habitat Directive. EU Member States propose candidate Sites of Community Interest (pSCIs), to be further designated as Special Areas of Conservation and be part of the NATURA2000 Network. Depending on the biogeographic context and countries, the pressures due to human activities that may influence the conservation status of such habitat vary in nature and intensity. The analysis is based on data by 1999 from 984 pSCI sites (91 mountain sites, 893 lowland sites) where dry or mesic grassland covered more than 30 % of the area. Data on impacts was available only from 9 countries for lowland areas and 7 countries for mountain areas. Source: ETC/NC, analysis based on data in European Commission database on pSCIs. Key messages K Except for very limited areas of special natural grassland types, all European grasslands are maintained through grazing or cutting, the continuation and intensity of which are crucial for the protection of the grasslands and the species they harbour. LÃPressure on grassland habitats is increasing steadily. Sixty percent of the newly afforested area in the EU was formerly permanent pasture or meadows, 37 % was arable land and only 3 % was permanent cropland. Ã B.

E. Results and assessment (level of the indicator) Relevance of the indicator for describing developments in the environment Permanent grasslands play a major, but not always well recognised or understood role for society (production, employment), the environment, and biodiversity. The grasslands are key habitats for many species: herbs, grazing animals such as deer and rodents, butterflies and reptiles, and many bird species. Dry grasslands contain some specialist species, for example orchids and butterflies, which can survive only in dry well-lit conditions. Grasslands, particularly calcareous grasslands, are an important habitat for orchids, and half of the orchid species in France, and between 35 and 42 % in Belgium, the Netherlands and Luxembourg, occur in dry and mesic grasslands. A high proportion of these are either in a highly vulnerable state or close to becoming extinct.
