Siebertal is a multi-part nature reserve along the Sieber in the Harz Mountains in the districts of Goslar and Göttingen in Lower Saxony .


The nature reserve with the sign NSG BR 105 is 694.7  hectares in size, of which 48.6 hectares are in the Goslar district and 646.1 hectares in the Göttingen district. It places parts of the Sieber river valley with valley and slope areas as well as those areas of its tributaries Dreibrode and Kulmke , the two source streams of the Kulmke ( Große Kulmke and Kleine Kulmke ) and the Lost Kulmke under protection. In this protected area, parts of the lie Karst landscape of Südharzer Zechsteingürtels with infiltration of Sieber .

The nature reserve is largely part of the FFH area “Sieber, Oder, Rhume”. It has been a nature reserve since June 16, 1992. Responsible lower nature conservation authorities are the districts of Göttingen and Goslar.

The originally 1016 hectare nature reserve initially also included the area from Bundesstraße 242 a little below the source of the Sieber on Bruchberg to the current start of nature conservation west of Sankt Andreasberg with the Schluft, Fischbach and Dreibrode tributaries. This means that almost the entire course of the Sieber, some 35 km long, was designated as a nature reserve. With the designation of the Harz National Park in the Lower Saxony part of the Harz Mountains on January 1, 1994, this part of the nature reserve became part of the National Park.

Location and description

The "Siebertal" nature reserve is located in the Upper Harz within the Goslar district in the urban area of Braunlage and the non- parish Harz region and within the Göttingen district in the city of Herzberg am Harz , the non- parish Harz region and the municipal areas of Hörden am Harz , Elbingerode and Hattorf am Harz in the joint municipality of Hattorf am Harz .

It is located between Sankt Andreasberg in the northeast and Hattorf am Harz in the southwest. The section between these two localities lies within the Harz Nature Park and borders the Harz National Park in the northeast and southwest . In Hattorf am Harz it borders on the " Oderaue " nature reserve .

The Sieber is in the resin in a wide range of semi-natural alder lined shore forest and flood plain many of mountain meadows and neglected grassland dominated. Mixed beech and spruce forests grow on the slopes . Also in the Harz foreland between Herzberg am Harz and Hattorf am Harz, the course of the river has a natural course with diverse bank vegetation. Herb-rich alluvial forest relics, willow bushes and tall herbaceous corridors as well as gravel corridors can be found on the gravel banks . The floodplain is often characterized by meadows and pastures, which are joined by mixed oak and beech forests between Herzberg am Harz and Hörden am Harz. The central terrace is in some parts marked as a steep edge.


In and near Sieber there are several references to former mining activities. Somewhat east of Sieber, near the confluence of the Kulmke and Sieber, is the former smelting site of the “Klockerhütte”, where various ores were extracted around 1600. Heavy metal flora has settled on the soil, which is contaminated with zinc, copper and lead compounds . A little to the west of this is on the Lilienberg with the "Henriettegang" a historical copper mine, in which copper was mined from 1550, as well as a tunnel for exploration. This tunnel is now used by bats as winter quarters. Another reference to former mining activities can be found in Sieber at the foot of the Breitental head. Here was the "Mittlere Sieberhütte", an ironworks.


The Sieber valley is the only large valley in the western Harz that is not blocked by a dam . The construction of the Siebertalsperre above Sieber was planned by the Harz waterworks until 1985 , but it was not realized. This should serve to generate energy and drinking water as well as flood protection in the southwestern Harz foreland.

The country road 521 runs from Herzberg through the Siebertal to Sieber and then to Königshof. From there it continues (blocked for trucks) over the Sieberberg to Silberhütte. Until March 31, 1989, a road from Königshof (as an extension of today's L 521) led along the Sieber to the B 242 northwest of Sonnenberg.

The Herzberg – Siebertal railway line , which was primarily used for freight traffic until the end of 1994, runs north-east of Herzberg through the nature reserve.
