The gypsum karst landscape near Ührde is a nature reserve in the Lower Saxony town of Osterode am Harz in the Göttingen district .

General

The nature reserve with the sign NSG BR 122 is 705  hectares . It is almost completely part of the FFH area "Gipskarstgebiet bei Osterode". In the southeast it borders on the nature reserve " Gipskarstlandschaft Hainholz ".

The area has been a nature reserve since April 26, 2007. The 15.6 hectare nature reserve "Lichtenstein" with the registration number NSG BR 036, which was designated on February 16, 1973, was incorporated into it. The responsible lower nature conservation authority is the district of Göttingen.

The nature reserve is located southwest of Osterode am Harz between the villages of Förste , Dorste , Ührde and Schwiegershausen . It places a section of the gypsum karst landscape of the southern Harz Zechstein belt under protection. In the nature reserve, which by an exceptionally moving small relief is embossed, are sinkholes , sinkholes , Bach disappearance , caves and karst formations than to find typical karst phenomena.

The area is comprised of mainly with natural beechwoods bestockte gypsum - and red sandstone surveys and grassland areas , but also areas with calcareous grasslands , as well as a portion of the valley area of the Dorster mill stream, which through marshy is embossed areas. In several places there are quarries on the edge of the nature reserve. Areas in the east of the nature reserve between Osterode am Harz and Schwiegershausen, in which gypsum mining is permitted, are left out of the nature reserve. The quarries are to be renatured after the end of their use .

The southern Harz karst hiking trail runs through parts of the nature reserve in the north.

Lichtenstein and Bauernberg

The Lichtenstein is a mountain in the Harz foreland southwest of Osterode am Harz between Förste and Dorste. It drops off steeply to the Söse valley in the west. The lower part of the mountain consists of Zechstein gypsum, in which numerous sinkholes and sinkholes have formed. The upper part of the mountain consists of red sandstone. The Bauernberg, a little to the south-east, has a similar structure.

In addition to eruptions and sinkholes, steep walls, fissures, carts and dry valleys can be found in the Lichtenstein area . In the mountains, grove beech forests grow on the red sandstone knolls as well as pearl grass beech forests in the hollows and grove beech forests on the gypsum ribs of the gypsum floors.

On the top of the Lichtenstein are the remains of the ruins of Lichtenstein Castle , which is a designated cultural monument . The Lichtenstein Cave, discovered in 1972, is located on the northwest slope of the mountain . This is designated as a natural monument .

In the east of the Lichtenstein there is a large quarry with a plaster work . The quarry was opened in 1952 and is now surrounded by the nature reserve. Fossils have been found in the quarry. There were further fossil finds in another quarry at Hopfenkuhle , a little to the southeast and on the other side of federal road 241 .

Sinkholes

At the edge of the quarry southeast of federal highway 241 is an area with several sinkholes along a geological fault in the underground.

A larger sinkhole area is located in the east of the nature reserve between Blossenberg, Langenberg and Heistermannsgrund. Large parts of the area served until 2003 as a training area for the stationed in Osterode am Harz Infantry Battalion 12th

Due to its use as a training area, the area is characterized by grassland areas with poor grass and bushes. The mountain tops are forested, in the sinkholes you can find canyon forests . The grassland areas are grazed with sheep. The former training site is characterized by a high level of biodiversity.

Parts of the former training area were sold after the deedication and the construction of quarries was approved.
