The East Brunswick Hügelland (also Ostfälisches Hügelland ) describes the hilly landscape between the fertile bordering landscapes of the Braunschweig-Hildesheimer Loessbörde in the west of Lower Saxony and the Magdeburg Börde in the east of Saxony-Anhalt . The inner German border ran through the landscape, to the west of it in the Elm at up to 323.3  m above sea level. NHN by far the highest and most formative mountain range. Between the mountain ranges of the Triassic , Jura and Cretaceous mountains , huge deposits of loess can be found again and again .

The Ministry for Spatial Planning, Agriculture and Environment and the State Office for Environmental Protection Saxony-Anhalt , who published a breakdown of the state into so-called "landscapes" in 2001, call the part of the East Brunswick hill country belonging to Saxony-Anhalt Börde-hill country .

location

The East Brunswick hill country extends in the core landscape from Brunswick in the northwest to Oschersleben in the southeast with the Oker around Wolfenbüttel in the west and the Großer Graben as the southern border. This area takes up about 50 km in a west-east direction and about half in a north-south direction. In addition, the edge heights of the Oker and the Oder forest are added to the west . Larger towns in the interior are only found in the western half of Lower Saxony with Schöningen in the center, Helmstedt in the north, Königslutter in the northwest and Schöppenstedt in the west.

The northern border of the landscape to the East Brunswick lowlands , which adjoins in the north, does not follow the altitude, as the name suggests, but the quality of the soil in the middle layers and lowlands. The Lappwald reaches up to 194  m above sea level. NHN almost the heights of its continuation to the southeast, reaching 211.1  m to the east of Sommersdorf and reaching up to the Hohen Holz (up to 208.8  m ), but due to the disappearance of the loess cover even on the flanks it belongs to the East Brunswick flatland, while its south-eastern continuation is in the Lee of the Elm is covered by Quaternary rocks up to the higher elevations . And the Flechtinger ridge to the east of the Lappwald, which reaches up to 179  m , clearly towers above the landscape of the hill country of East Brunswick that adjoins it to the south.

To the south, the landscape drops significantly towards the neighboring natural area of Großes Bruch (main unit 511), to the south of it the Harz rim hollow (510), which is also characterized by island-like ridges, but has a lower ground level overall. Together with both of them, the hill country of East Brunswick (512) forms the main unit group 51 Northern Harz Foreland . Like the Braunschweig-Hildesheimer Börde in the west and the Magdeburger Börde in the east, this belongs to the natural spatial greater region of the 2nd order of the Lößbörden , which, directly in the northern connection to the low mountain range threshold , extends from Lübbecker Loessland in the west on German soil to Upper Lusatia pulls.

Natural structure

The East Brunswick hill country was defined in the Handbook of Natural Spatial Structure of Germany in the first mapping from 1954 and, based on those boundaries, is specified in the 6th edition of the Handbook from 1959 with an area of ​​1277.1 km². An updated map was published in 1960. Theodor Müller , who had also written the relevant section in the manual, gave a more detailed breakdown in 1962 on single sheet 1: 200,000 87 Braunschweig. The Federal Agency for Nature Conservation, based on Sheet 87 Braunschweig, has determined an area totaling 1349 km².

In the following all sub-natural areas of the East Brunswick hill country are given; In addition, for (possibly island-like) mountain ranges, the altitude above sea ​​level and the surrounding rock ( red sandstone , shell limestone , Keuper , Jura , chalk and loess ) are listed:

The Eggenstedt-Marienborn ridge (512.3), which extends the Lappwald (624.3) to the south-east, separates a purely Saxon-Anhalt eastern part, which in the interior still clearly has characteristics of the Magdeburg Börde (504). The loess-rich landscapes of this triangle are framed to the southwest by the Oberallerniederung (512.4) and separated from the Magdeburg Börde to the east-southeast by the Druxberg range of hills (512.53); in its interior lies the depression of the Seelschen Bruch (512.51).

In the Helmstedt-Oschersleben Mulde (512.2), which hugs the Eggenstedt-Marienborn ridge to the south-west, the loess thickness drops significantly from south-east to north-west; The Oschersleben Mulde (512.22), which is located significantly northwest of the eponymous city ​​with Ausleben in the approximate center, still has a clear Börden character, while the Helmstedter Mulde (512.21) immediately east of the Elm (512.15) only in the areas around Schöningen and Süpplingen is comparably well equipped. The Dormhügelland (521.20) closes the landscape to the north with the last two mountain ranges worth mentioning.

In the Asse-Elm-Hügelland (512.1), which stretches from the Elm to the southwest to the mouth of the Schiffgraben in the Oker, rocks of the Triassic come to the surface in mountain ranges . Only to the left of the Oker and north (512.02) to west (512.00) of the Oderwald (512.01) do the loess thicknesses typical of the region appear again in the Okerrand heights (512.0), which come close to those of the Braunschweig-Hildesheimer Loessbörde (520) to the west . Both of these partial landscapes are almost entirely included in the Braunschweig-Hildesheimer Börde both on the maps for the manual and on other structures (e.g. Günther Schönfelder 2008). Especially the Beinumer Mulde (512.00) would be a natural continuation of the Lebenstedter Börde (520.6) to the southeast.
