The plateaus in the southern Maindreieck are a small-scale natural spatial unit (5th order) with the order number 134.11 in the area of the municipalities of Biebelried , Buchbrunn , Dettelbach , Estenfeld , Gerbrunn , Kitzingen , Kürnach , Mainstockheim , Ochsenfurt , Randersacker , Rottendorf , Sulzfeld am Main and Theilheim in the districts of Kitzingen and Würzburg .
location
The plateaus in the southern Maindreieck (134.11) form a sub-unit within the main unit of Inner Gahe Plateaus in the Maindreieck (134.1). They are part of the Gäuf areas in the Main Triangle (134) and thus a natural area in the main unit group of the Mainfränkische Platten . To the north, the Gäuf area joins the northern Maindreieck (134.10). To the east is part of the Middle Main Valley (133), the Kitzinger Main Valley (133.05). The south is also taken by the Main, here the Würzburg-Ochsenfurter Main Valley (133.04) connects. In the west, the natural area is bounded by the Würzburg basin (133.03). Only in the southwest does not the Main, but the extensive drifting sand area around Lindelbach (134.2) form the border. The Würzburg northern Main side valleys (135.0) as part of the Wern-Lauer-Platten (135) can be found in the northwest.
The plateaus occupy an extraordinarily large area, which distinguishes them from the otherwise rather small-scale natural units along the main triangle . The northern border forms the area of the municipality of Kürnach in the district of Würzburg. The natural area cuts through the municipality of Dettelbach and runs through the Euerfelder and Bibergauer districts. The southernmost point is the Segnitz and Kleinochsenfurt districts . Erlach is also in the plateau, while the places Sommerhausen and Eibelstadt are no longer part of the natural area. The densely built-up areas around Würzburg already begin in the west around Gerbrunn and Randersacker . The proximity to Würzburg is also evident from the many roads that cross the area. These are the Würzburg-Nuremberg and Würzburg-Bamberg railway lines , as well as the federal motorways 3 and 7 .
Landscape characteristics
The natural area presents itself as a 300 m high Gäu plateau with a steep drop to the main valley. The plateaus rise gently until shortly before reaching the main valley, so that this steep slope is reached. The smaller Main tributaries that cut through the area have produced a comparatively steep bank (so-called blades ), which have recently been deepened by anthropogenic interventions. The streams here usually do not carry any water in summer.
Today the landscape is characterized by extensive arable land on which mainly wheat, brewing barley and sugar beet (in the Ochsenfurt area) are grown. In addition, suburban development is well advanced here. Historically, forest areas that were interspersed with permanent grassland predominated here . They can only be found around Kitzingen-Sulzfeld (Nonnenholz) and Kürnach (Hart). The potential natural vegetation (without human intervention) would produce extensive alluvial forests here , only spruce would be found along the streams .
Protected areas
Due to the dense population, only a few protected areas have been designated in the natural area. The only nature reserve is the Marsberg-Wachtelberg in the north-west , which is also part of a large fauna and flora habitat . The Zeubelried Moor , on the other hand, can already be assigned to the Lindelach drift sand area. The Ortolan areas around Erlach and Ochsenfurt are a large bird sanctuary that lies in the center of the natural area. The Ochsenfurter Forst and Hübnerholz, on the other hand, are designated as landscape protection areas.
Geology and tectonics
The soil compositions form the brackets that hold the extensive natural space together. The area is characterized by hard shell limestone subsoil under softer Lettenkeuper with loess clay blankets . It was this composition that made the deep cuts in the stream valleys possible. Para brown earths developed on this mixture .
