The dry habitats - seven mountains, foothills are a nature reserve in the Lower Saxony town of Alfeld (Leine) and the municipality of Sibbesse in the Hildesheim district .

The nature reserve with the sign NSG HA 241 is about 153  hectares . It is part of the FFH area “Seven Mountains, Foothills”. The previous nature reserve " Unterer Lauensberg " as well as parts of the nature reserves " Karlsberg ", " Schiefer Holzer Berg " and " Wernershöhe " and the landscape protection areas "Sieben Berge und Vorberge" and "Sackwald" have also merged into the nature reserve as the previous one, about 1, 2 hectare natural monument "Abbenser Berg". The partial areas of the nature reserve are largely surrounded by the landscape protection areas “Seven Mountains and Foothills” and “Sackwald”. The nature reserve has been under protection since December 28, 2017. The responsible lower nature conservation authority is the Hildesheim district.

The nature reserve consists of seven sub-areas in the seven mountains and foothills of the Leinebergland lying north and northeast of Alfeld . It places dry habitats and isolated forest areas under protection. The majority of the areas under nature protection are taken up by semi-arid lawns, which were created through historical use as pasture for sheep and goats. In addition to the semi-arid lawns, there are dry bushes, field trees, fringes and individual fruit trees and orchards as well as lean grassland . The forest areas are characterized as beech forests (orchid-beech forest or woodruff-beech forest) and oak-hornbeam forests , which have arisen as low or medium forests as a result of historical management .

Sub-areas of the nature reserve

Lower Lauensberg

Lower Lauensberg

The sub-area "Unterer Lauensberg" ( ⊙ ) is located north of the Alfeld district of Eimsen . It replaces the previous nature reserve of the same name that was designated on May 8, 1986 .

In the north-west there is a deciduous forest that emerged from a previously managed coppice forest. To the northeast and south, forests of the Seven Mountains adjoin, in the northwest and west the area borders on agricultural areas , from which it is separated by dirt roads .

Ortsberg

The sub-area "Ortsberg" consists of two sub-areas ( ⊙ and ⊙ ), which are located northeast of Alfeld or north of the Alfeld district of Langenholzen on slopes of the Ortsberg that are mainly exposed in southern and western directions. The two areas are characterized by a mosaic of semi-arid grassland, orchid-beech forest, coppice forest, dry bushes and hedges . These are essential structures of the historically grown cultural landscape of the southern Lower Saxony mountain and hill country, which have been preserved here, so that the area is a valuable document of landscape history.
