The Abraham is a small mountain range in the Calenberger Land .
geography
Abraham is located northeast of Eldagsen in the Hallerburg area in the municipality of Nordstemmen in the district of Hildesheim and in the urban area of Springe in the Hanover region in Lower Saxony . The highest point is 134 meters above sea level . Partly less than 200 meters away, the Haller flows less than 80 meters above sea level, so that the Abraham can be recognized as a mountain range.
To the east is the Hallerburger Holz forest area , as one of the FFH areas in Lower Saxony in the European Natura 2000 protected area system . In 1972, a natural forest reserve was designated in the southwestern part of the Hallerburger Holz , which was excluded from forest use and was to develop into a primeval forest in the long term. This natural forest reserve was dissolved in 1990 and the further development of the natural forest, which had previously been under special protection, was canceled.
The southwest side of the Abraham is used for agriculture , in accordance with the prevailing loess soils .
geology
The Abraham is located in a layered landscape in which the particularly solid rocks of the Abraham rise up in a railing rib. In the south and west of Gestorf, the solid rock of the Jura was cut through by the Limberg thrust (also known as the Limberg axis ), in which layers of the Triassic , which are rooted on layers of the Upper Buntsandstein , were pushed onto the layers of the Jura.
The towering layers of Lower Muschelkalk , Middle Muschelkalk , Upper Muschelkalk , Middle Keuper , Upper Keuper and Upper Buntsandstein form the Limberg , Abraham , Haarberg and Hallerburger Holz mountain ranges between Bennigsen and Hallerburg . The Hallerburger Holz forest area is one of the FFH areas in Lower Saxony in the European Natura 2000 protected area system .
The oldest rocks that come to light on Limberg and on Abraham were formed in the Triassic period about 240 million years ago in a low coastal sea of the ocean. At that time, the Germanic Basin in the European continent was temporarily flooded by the ocean. The sea deposits were mined in some quarries on Abraham. They contain numerous fossils of marine life; therefore this sequence of rocks is also known as shell limestone . In addition to the eponymous mussels, these layers also contain snails, cephalopods and, in some cases, large amounts of remains of sea lilies .
The landscape protection area "Gestorfer Lößhügel"
The Abraham lies together with the "Haarberg" and the "Limberg" in the LSG-H 74 "Gestorfer Lößhügel" nature reserve. The text of the regulation is reproduced in extracts below:
"The border of the landscape protection area runs west of Gestorf along the K 216 in a westerly direction until just before the K 215. Here it swings south in the direction of the Haller lowlands. Even before the Haller lowlands, the border runs in a south-easterly direction to the regional border, with which it runs identical over a length of approx. 2 km to the east. Then it swings to the northwest, crosses the L 422 north of the Haarberg forest area and is led again to the north on the K 216. "
"The protected area is located in the natural area of the" Kalenberger Loessbörde "and is to be assigned to the natural spatial unit" Eldagser Loesshügel ". The special importance of the area results from the diversity of the individual habitats in a landscape that is characterized in particular by hilly forms of the Gestorfer Loesshügel soils with the highest creditworthiness predominate, which, due to their fertility, enable intensive agricultural use. Particularly characteristic of the landscape are the prominent hills protruding into the terrain, which are almost completely covered with forest. Due to their old age and their species composition, these forest areas are of Particularly high importance is attached to nature protection. These are historical forest locations overgrown with species-rich mixed forests of beech and oak and hornbeam. In large parts their composition corresponds to potentially natural vegetation. They have numerous orchid locations m it is a species-rich expression. In places they are interspersed with non-native wood species such as poplar and spruce. Individual field trees, hedges, rows of trees, individual trees as well as grass and herb fringes that can be found in the area enliven the landscape and have a high ecological value, as they serve as a retreat and stepping stone biotopes for a variety of animal species due to their location in the agricultural landscape. Small bodies of water in a near-natural form are embedded in woodland southwest of the Limberg. "
