The Weser-Aller Plains and Geest [1] (German : Weser-Aller-Flachland) is a natural regional unit of the North German Plain in Germany. It extends over most of the southern catchment of the Aller including the lower reaches of the Oker and Leine and is bounded in the west by the Middle Weser.
It is also bounded, from a natural region perspective, by the Stade Geest, the Luneburg Heath, the Wendland and the Altmark in the north; in the east by the Central German Black Earth Region (Mitteldeutsches Schwarzerdegebiet), in the south by the Northern Harz Foreland and Lower Saxon Börde and, in the west, by the Dümmer-Geest Lowland and Ems-Hunte Geest. [2] [3] In the BfN numbering scheme it is number D31.
In the system of natural regions of Germany the Weser-Aller Plains are a tertiary level major region and major unit group (Number 62, two-digit) within the North German Plain (primary level major region). They are split as into the following major units (fourth level regions, three-digits) : [4] [5]
Lower Saxony is a German state in northwestern Germany. It is the second-largest state by land area, with 47,614 km2 (18,384 sq mi), and fourth-largest in population among the 16 Länder federated as the Federal Republic of Germany. In rural areas, Northern Low Saxon and Saterland Frisian are still spoken, albeit in declining numbers.
Hunte is a 189-kilometre (117 mi) long river in north-western Germany, a left tributary of the Weser.
The North German Plain or Northern Lowland is one of the major geographical regions of Germany. It is the German part of the North European Plain. The region is bounded by the coasts of the North Sea and the Baltic Sea to the north, Germany's Central Uplands to the south, by the Netherlands to the west and Poland to the east.
This division of Germany into major natural regions takes account primarily of geomorphological, geological, hydrological, and pedological criteria in order to divide the country into large, physical units with a common geographical basis. Political boundaries play no part in this, apart from defining the national border.
The Stade Geest is a natural region of low, sandy heath (geest) in the North German Plain.
The Westphalian Lowland, also known as the Westphalian Basin is a flat landscape that mainly lies within the German region of Westphalia, although small areas also fall within North Rhine and in Lower Saxony. Together with the neighbouring Lower Rhine Plain to the west, it represents the second most southerly region of the North German Plain, after the Cologne Bight. It is variously known in German as the Westfälische Bucht, the Münsterländer or Westfälische Tieflands- or Flachlandsbucht.
The West Hesse Depression is part of the West Hesse Highlands and Lowlands region in the north of the German state of Hesse. Like the East Hesse Depression, it is a series of separate depressions that form a natural corridor and have been an important historical trade route.
The Gäu Plateaus form the largest natural region in the German state of Baden-Württemberg. Not surprisingly, the individual geographical units of this large region show considerable variations in climate and soil types. A common feature of the region, however, is its landscape of flat-topped hills of Muschelkalk, gently rolling tracts of loess and plateaus in which the layers of Muschelkalk have been covered by sediments of Gipskeuper and Lettenkeuper.
The Leine Uplands is a region in Germany's Central Uplands which forms a part of the Lower Saxon Hills and lies along the River Leine between Göttingen and Hanover. It borders on the Weser Uplands in the west, the Innerste Uplands in the northeast, the Harz in the east and Untereichsfeld in the southeast.
The Middle Weser Valley is part of the Weser Depression around the River Weser on the North German Plain, extending from the gap of Porta Westfalica to the town of Hoya. It is not a true valley, because it is only bordered by low hills at two points. It lies in the German federal states of Lower Saxony and North Rhine-Westphalia.
The Weser Depression or Weser Lowlands is the region north of Porta Westfalica in Germany, where the River Weser no longer flows through a valley, but a broad plain consisting of meadows and river terraces.
The Rahden-Diepenau Geest is a natural region in the extreme northeast of North Rhine-Westphalia and in the neighbouring state of Lower Saxony in north Germany. It includes the overwhelmingly gently rolling geest between the Lübbecker Lößland to the south, the Diepholz Moor Depression to the north, the Middle Weser Valley to the east and the western Wiehen Hills and Bersenbrück Land to the west. The Rahden-Diepenau Geest is part of the Dümmer Geest Depression and thus belongs to the North German Plain, although they include foothills of the Central Uplands in the shape of the Stemmer Berge.
The Franconian Keuper-Lias Plains or Franconian Keuper-Lias Lands are a major natural region in the South German Scarplands in Upper Franconia and to a lesser extent in the north, in the Thuringian district of Hildburghausen. As the name indicates, the term embraces both the Keuper landscapes and lias landscapes in Franconia. In addition, the fore-land of the Franconian Jura, in which part of the Brown Jurassic occurs, as well as parts of the former volcanic region of Heldburger Gangschar belong to this region.
The Saar-Nahe Hills or Saar-Nahe Uplands is a major natural region in the German states of Rhineland-Palatinate and the Saarland. The region of hills and mountains covers an area of 4,185 km² running from Saarbrücken, Kaiserslautern and the Palatine Forest in the south to the Hunsrück in the northeast. It contains the catchment area of the Nahe as far as Bad Kreuznach as well as small sections of the Middle Saar in the west.
Wendland and Altmark, named after the German regions of Wendland and Altmark, is the name of a natural regional major landscape unit group in Lower Saxony and Saxony-Anhalt, North Germany. In the Handbook of Natural Region Divisions of Germany it is given serial number 86, the Bundesamt für Naturschutz gives the same region the serial number D29.
The Upper Palatine-Upper Main Hills, also called the Upper Palatine-Upper Main Hills and Uplands form a landscape of low, rolling hills between the Franconian Jura in the southwest and the Franconian Forest, Fichtel Mountains and Upper Palatine Forest in the northeast.
The Dümmer Geest Lowland is a natural region unit of the 3rd level in northwest Germany that mainly extends over southwestern Lower Saxony with a small area over the border in North Rhine-Westphalia. Its uniqueness consists in the very varied juxtaposition of different landscape elements of the Northern Lowlands of which the Dümmer Geest Lowland is a part.
The North Brandenburg Plateaux and Upland is a natural region in the northwest of Brandenburg and, to a lesser extent, the southwest of Mecklenburg-Vorpommern and northeast of Saxony-Anhalt in Germany. It is major unit group no. 77 in the natural regional divisions of Germany. The Brandenburg portion of the North Brandenburg Plateaux and Upland is largely coextensive with the natural region of Prignitz and Ruppin Land in the structural atlas of the state of Brandenburg.
