steppe grasslands in Thuringia
More often than not, steppe grasslands are interspersed with submediterranean orchid-rich oligotrophic calcareous grasslands and calcareous areas colonized by pioneer species. In the Bottendorfer Hügel nature conservation area, they also occur in areas adjacent to calaminarian grasslands. In central Europe, there are only very small areas of natural woodless dry and semi-dry grasslands. They are limited to very steep, rocky, dry and warm sites. Far more often, we find “secondary” dry and semi-dry grasslands that have developed on abandoned fields and vineyards with shallow soils over the last centuries. Their biodiversity can only be conserved if they are subject to sheep and goat grazing on a regular basis. What is life+? Launched in 1992, life (L’instrument financier pour l’environnement – The Financial Instrument for the Environment) is the financial instrument of the European Union supporting environmental and nature conservation projects. The funding within the programme part life+ nature serves to protect habitats and animal and plant species that are regarded as European Natural Heritage. The funding is therefore restricted to areas proposed to be identified and designated by the European Commission as Special Areas of Conservation (sacs) under the Habitats Directive or Special Protection Areas (spas) under the Birds Directive. Thus Life projects contribute to securing the European Natura 2000 network of protected sites.

Becker, D.Stremke, H.Wiesbauer, K.Bogon | May 2010 steppe grasslands in Thuringia Steppe grasslands are dry grasslands and semi-dry grasslands dominated by great feather grass, spring pheasant’s eye and other species that are continentally distributed. They predominantly occur in areas with an average annual precipitation of less than 500 millimetres. In Thuringia, they are mainly found on the Keuper hills of the Thuringian Basin and in the Zechstein belt of the Ky¤häuser Mountain and of the Bottendorfer Höhe. Small areas of steppe grasslands also occur on dry and warm lime stone hillsides and on the loess islands of the Hainleite area. They can be regarded as the “outposts” of the steppe of eastern Europe. The steppe grasslands on slopes with shallow gypsum, clay or lime marl Rendzina soil that are exposed to south and west sites often live under extreme conditions: drought stress, weak soil development, wind and water erosion, and they can even turn into “Badlands” – like those in the Drei-Gleichen area and the Schwellenburg nature conservation area. project areas with steppe grasslands in thuringia The life+ nature project is managed by the Thuringian Ministry for Agriculture, Forestry, Environment and Nature Conservation (Thüringer Ministerium für Landwirtschaft, Forsten, Umwelt und Naturschutz – tmlfun). It comprises 13 project areas in the rural districts Ky¤häuserkreis (excluding the Ky¤häuser Mountain), Sömmerda, Unstrut-Hainich-Kreis, Gotha, Ilmkreis and Erfurt, the state capital. With a duration of six years (2009-2014) and a total budget of five million Euros, more than 90 individual projects will be implemented. Due to the outstanding significance of this project, the maximum funding rate of 75 percent has been granted by the European Commission. The remaining 25 percent is funded by the Free State of Thuringia. wip How can steppe grasslands be conserved?
