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.

  • Lowland Grassland Timescales to Achieve Favourable Condition Introduction
    Rehabilitation of existing priority lowland grassland Timescales to achieve favourable condition Introduction This advisory note identifies the length of time that different management practices take to achieve favourable condition on existing priority lowland grassland habitats. The timescales and interim indicators can be used to assess the trajectory of site condition and whether habitat condition is progressing in a positive or negative direction. Lowland grassland priority habitat encompasses a range of species-rich semi-natural grassland communities. They have declined over the second half of the 20th century, a variety of causes including agricultural improvement, urban development and abandonment where management cannot be continued or is no longer economically viable. Lowland grassland is still under threat and rare, covering around 3% of England’s area, with an estimated 7,282 ha of lowland meadow, 870 ha of upland hay meadow, 38,687 ha of lowland calcareous grassland and 20,142 ha of lowland dry acid grassland (Bullock et al. 2011). The priority lowland grassland habitats featured in this advisory note include: Lowland meadows – including dry and floodplain hay meadows and pastures. National Vegetation Classification (NVC) categories MG4-5 and MG8. Upland hay meadow – dry and floodplain hay meadows and pastures that usually occur at less than 300 m in upland landscapes, and are generally managed in a similar manner to lowland meadows (mostly dry grassland). NVC categories MG3 and upland forms of MG8. Lowland dry acid grassland – including species-rich bracken stands and inland dune grassland. NVC categories U2-U4, U4/20 and SD10-11. Lowland calcareous grassland - NVC categories CG1-10.

However, to date there is no systematic glo- bal characterization and distribution map for grassland types. To address this gap, we first propose a systematic definition of grassland. We then integrate International Vegetation Classification (IVC) grassland types with the map of Terrestrial Ecoregions of the World (TEOW). Location Global. Methods We developed a broad definition of grassland as a distinct biotic and ecological unit, noting its similarity to savanna and distinguishing it from woodland and wetland. A grassland is defined as a non-wetland type with at least 10% vegetation cover, dominated or co-dominated by graminoid and forb growth forms, and where the trees form a single-layer canopy with either less than 10% cover and 5 m height (temperate) or less than 40% cover and 8 m height (tropical). We used the IVC division level to classify grasslands into major regional types. We developed an ecologically meaningful spatial cata- logue of IVC grassland types by listing IVC grassland formations and divisions where grassland currently occupies, or historically occupied, at least 10% of an ecoregion in the TEOW framework. Results We created a global biogeographical characterization of the Earth’s grassland types, describing approximately 75% of IVC grassland divisions with ecoregions.

  • Lowland Dry Acid Grassland 1
    LOWLAND DRY ACID GRASSLAND 1 Action Plan Scope: This action plan covers the UK BAP priority habitat Lowland dry acid grassland1. This habitat typically occurs on nutrient poor, generally free-draining soils that have developed on acid rocks or superficial deposits such as sands and gravels. Lowland dry acid grasslands often occur as an integral part of lowland heath and upland fringe “ffridd” landscapes, on commons, and locally on rock outcrops, wind-blown sand and river shingle. They are normally managed as pasture, and usually grazed by sheep. In Gwynedd, lowland acid grassland often forms a vegetation mosaic with heathland, which is covered by the Lowland heathland HAP. This Action Plan covers all unimproved and semi-improved acid grasslands below the ffridd wall (or below about 300m altitude), but is focused particularly on lowland examples, as most of the scarcer vegetation types and associated species are found here. On higher ground, lowland acid grassland is often a modified community that has replaced dwarf shrub heaths of primary conservation interest. 1. CURRENT STATUS 1.1 Legislation and priority status International Habitats Directivea Birds Directiveb UK and Wales SSSI legislationc (some lowland dry acid grasslands) UK BAP priority CROW Act 200d Gwynedd LlƄn AONB Heritage Coast 1.2 Status in Wales and beyond An estimated 40,000 ha of lowland acid grassland is found in Wales, mostly around the upland fringes.

Although their plant community types have been described in detail, the diversity patterns and their environmen- tal determinants are still poorly known for these grasslands. Here, we study environmental drivers of species composition and richness in dry grasslands of northern Bohemia (České středohoří Mts) and central Bohemia (Křivoklát region), both in the Czech Republic. In vegetation plots of 100 m² we recorded all vascular plant species, measured soil chemistry variables, above-ground biomass produc- tion and nutrient concentrations in biomass. Species richness in these plots ranged from 13 to 55.

  • The High Nature Value Dry Grasslands of Southern Transylvania
    The High Nature Value dry grasslands of southern Transylvania 6210 * Scrub habitats and semi-dry grassland over limestone or other calcareous substrates ( Festuco-Brometalia ), with important orchid sites 6240 * Sub-Pannonic steppic grasslands John Akeroyd and Sabin Bădărău The High Nature Value dry grasslands of southern Transylvania Romania retains extensive tracts of traditionally farmed landscapes dominated by semi-natural grasslands. The meadows and pastures of southern Transylvania are some of last remaining ecologically-intact traditional grasslands in Europe, with extensive farmland, mixed arable and pastoral farming, non-intensive farming practices, minimum use of fertilizer (or even no use at all) and well-managed grazing. These factors have allowed the survival of an extraordinary diversity of wild plants and animals in one of Europe’s last great High Nature Value (HNV) landscapes. Even by Romanian standards, the Sighișoara-Târnava Mare area is extremely rich in dry HNV grassland. This reflects over 800 years of careful farming since the arrival of the ‘Saxon’ immigrants from Flanders, Luxembourg and NW Germany, which has allowed the survival of rich biodiversity. The grasslands are not only the habitat for many species of plants and animals that have disappeared from other parts of Europe, but also provide a great visual spectacle, especially in summer. Like the famous fortified Saxon churches, these grassland landscapes are a significant element of the cultural identity of southern Transylvania and a major attraction for visitors. The area is, however, no rural museum but a dynamic landscape, in which farming communities live and contribute to the economic development of the region. The diversity of grasses and wild flowers, especially clovers, vetches and other legumes (in the same family as peas and beans) provides an in - valuable source of feed for farm animals.

In the southern Harz and Kyffhäuser Mountains dry grasslands are found on calcareous soils on gypsum bedrock along a steep climatic gradient. With only little differences in soils and land use, climate can be assumed to be the main factor controlling the occurrence of different vegetation types of dry grasslands. For gradient studies at broader scales, climate data are normally available only from official weather stations and, thus, refer to macroclimate. As the microclimate encountered by plants on a specific site usually differs considerably from standard weather station recordings, this paper addresses the questions (1) whether a gradient in the study area is also apparent in microclimate,
