      Biosphere Reserve Information



  General Description   The “Biosphäre Bliesgau” biosphere reserve features a high degree of spatial and historic complexity within a relatively small area (approx. 36,152 ha), simultaneously in abiotic, biotic and social respects. This degree of social complexity arose from the historic development from initially close and increasingly loosening ties to nature. The less fertile forested Buntsandstein areas in the North are contrasted with more fertile, largely
extensively farmed Muschelkalk areas in the South. Moreover, they exhibit an extremely large variety of soils and microclimates. Correspondingly, the South is characterized by a partially preserved rural way of life and by its relatively sparse population. In contrast, the northern portion of the biosphere reserve is
densely populated and characterized by urbanization. A broad suburban transition area is located in between these zones.
Due to its industrial and service sectors, the North constitutes the economic center of the region. Economically, the South is highly dependent on the North. The region is oriented toward intermediate-order and high-order central places, some of which are located within the biosphere reserve and others outside of
it. This results in interferences between humans, society and the environment that are clearly reflected in the landscape. This diversity of landscapes and habitats results in high species and habitat diversity of national significance.
The entry of the entire medium-sized town of St. Ingbert into the biosphere reserve presents a diversity of additional options. They range from added value and valorization of regional products at a medium-sized regional center with the appropriate infrastructure and purchasing power to the exemplary sustainable
development of old heavy industry sites.
Especially due to its close proximity of rural, suburban and urban areas, its high population density (an average of 337 km2 and approx. 111,000 inhabitants in the planned area) and the resulting high degree ofcomplexity, the biosphere reserve offers a good basis for the development and testing of potential sustainable solutions
  Major ecosystem type   In addition to urban habitats, hilly mesophilic beech forests of the Upper Buntsandstein and swampy floodplain valleys dominate the landscape in the northern urban areas. Characteristic elements of the southern rural areas include semi-arid grasslands, extensive infertile flatland mowing grasslands (largely sage-false oat grasslands), Streuobst complexes and orchid and woodruff-beech forests on Muschelkalk.
  Major habitats & land cover types   Forests, Hedges and thickets, Grassland habitats, Infertile grassland, Bogs and swamps, Bodies of water, Dwarf shrub heaths, Ruderal communities, Fields, Open rock formations, quarries, sand pits, settlement areas.
