RETEZAT

  General Description   This biosphere reserve is situated in the southern Carpathian Mountains and has an altitude range from low mountain ranges to alpine landscape. Peak Peleaga with 2,509 meters above sea level is the highest elevation in the biosphere reserve. The Retezat Massif is a well-defined upland block, separated on most sides from the rest of the range by deep valleys and to the north overlooking the Tertiary Hateg basin. The area was glaciated in the quaternary and has many landforms caused by glacial erosion. This biosphere reserve is significant for the conservation of European mountain forest diversity. The vegetation is very diverse due to the varied relief and the junction of three floristic regions in this area.
The biosphere reserve is not inhabited, however rural communities outside the biosphere reserve depend on agriculture, livestock raising and forestry. Impacts on the environment come from overgrazing and recreation activities. In this region, people from different origins (Romania, Hungary, Germany and Serbia) are living together.
  Major ecosystem type   Temperate and sub-polar broadleaf forests or woodlands (Coniferous forest, Mesophyllous broad-leaved forests, Mixed broadleaved and coniferous woods, Cryophyllous alpine grasslands, Mesophyllous grasslands, Saxicole and petrophyllous formations, Cryophyllous small alpine bushes, Subalpine bushes)
  Major habitats & land cover types   a) Natural and semi-natural habitats:
Alpine and subalpine grasslands; alpine and subalpine scrub; bogs, mires, fens; cliffs, rock outcrops and shelves (siliceous and basic); coniferous woodland, deciduous broadleaved forest; dry grasslands; inland surface waters (running and still), together with their littoral zones; ; mesic grasslands; mixed broadleaved and coniferous woods; riparian scrub; scree slopes; shrub habitats; snow-patch habitats; sparsely or unvegetated areas; terrestrial underground caves and waterbodies; wet grasslands; woodland fringes and clearings (tall grass/fern)
b) Strongly anthropogenic habitats include:
Artificial water structures; man-influenced woods/cleared areas; settled areas; transportation networks and their margins
c) Special features: Within these broad EUNIS types, certain habitats are of special national and international importance. There are >80 glacial lakes (largest is Bucura at 2041m and 8.86 ha). Forests (broad-leaved, coniferous and mixed) include a number of local and distinctive Carpathian and Dacian types, displaying a distinct altitudinal zonation: 650-1,650m: Quercus petraea, Carpinus betulus and Tilia cordata giving way above to Fagus sylvatica and Abies alba, or Picea abies mixed with Fagus, or Picea alone in the upper area; Subalpine levels have dwarf-pine (Pinus mugo) up to 2,300 m, with occasional Arolla Pine (P. cembra) and areas of both Rhododendron myrtifolium and Alnus viridis. The alpine area is mainly siliceous, but with strongly basic areas in the Little Retezat. As well as having a very rich assemblage of both animals and plants, the Retezat is a centre of diversity and endemism for Hieracium (257 taxa) and Poa (31 taxa). More than 60 plant communities are described for the Park.
