Top 20 Natural Monuments around Rümpel

The Herrenteich Pond is located in the heart of the carp town of Reinfeld. It was artificially created in the 12th century by Cistercian monks as a reservoir for the Heilsau River for fish farming. Carp are still bred here today. A four-kilometer circular trail around the Lower Herrenteich invites you to discover this special ecosystem. 16 stations along the adventure trail offer fun and a nature experience in one, sharpening your awareness of the special features of this natural area. In summer, you can enjoy the cool water at the lido. See: https://tourismus-stormarn.de/de/naturerlebnis/herrenteich-reinfeld-5

The Herrenteich in Reinfeld is a popular tourist destination. The approximately 55-hectare body of water is divided into the upper and lower Herrenteich. The upper Herrenteich remains a recognized nature reserve. The lower Herrenteich is home to, among other things, a hiking trail and an outdoor pool in the summer. Due to melting snow, the Herrenteich flooded in early March 2010. A temporary dam erected at the time due to construction work threatened to no longer hold the water masses. A breach of the dam would have flooded the entire hinterland. The Hamburg/Lübeck railway embankment would also have been affected.

The Nienwohlder Moor lies on the watershed between the North Sea and the Baltic Sea.[2] It drains to the west into the Lankau, to the south into the Alte Alster, and to the north into the Norderbeste. The nature reserve, which is managed by the Schleswig-Holstein State Hunting Association with the exception of the areas owned by the State Forestry Administration[5],[6] can be almost completely circumnavigated on hiking trails, along which information boards are posted at several locations. In the west, a hiking trail runs through the protected area in the area of the Lunden, a towering moraine ridge.

Today, typical raised moor vegetation can once again be found in the nature reserve, including round-leaved sundew, narrow-leaved cottongrass, bladderwort, white beak sedge, sedge cottongrass, cranberry, as well as cross-leaved heather, rosemary, and common heather. The nature reserve also represents an important habitat for birds. Various wading birds such as the curlew and the common snipe, as well as ducks such as the shoveler, teal, tufted duck, and garganey, as well as meadow pipits, whinchats, and stonechats, are native here. Marsh harriers and short-eared owls can also be found here. The undisturbed moorland is a refuge for cranes, which are now breeding here again. Various woodpecker species, red-backed shrikes, and songbirds are native to the wooded moorland areas. The nature reserve also provides a habitat for various amphibians and reptiles, as well as insects such as dragonflies and butterflies.

The moor was renaturalized in the 1980s through rewetting measures.[2][3] Today, in the area of former industrial use, it is an open raised bog with numerous water-filled peat pits, surrounded by a bog forest. The farmer's hand-cut peat pits at the edge of the moor are often water-filled. Sphagnum moss quaking grassland grows here, and the peat pits are slowly silting up. Further areas are occupied by grassland and forest. Some of the grassland is extensively grazed by robust cattle.[4] Some areas are still intensively used for agriculture, including one arable area.

Peat extraction, first documented in 1804, was initially carried out by peat-cutting by peat-farmers, and the peat was used as fuel. During the Napoleonic Wars of 1806–1813, peat was also shipped to Hamburg via the Alster. In the 20th century, peat extraction became an industrial operation. From 1951 to 1976, the white peat was extracted from an area of 84 hectares, initially by hand and later by machine.[2] East of Nahe, there was a peat loading point on the Elmshorn-Barmstedt-Oldesloe railway.

The nature reserve is located northeast of Hamburg between the towns of Nienwohld, Nahe, Itzstedt, and Sülfeld. It protects a drained and largely peat-extracted raised bog area, which is the largest and best-preserved raised bog remnant in Schleswig-Holstein.[2] To the north, it borders the former Elmshorn-Barmstedt-Oldesloe Railway line.

The approximately 398-hectare nature reserve is registered under number 100 in the register of nature reserves of the Ministry of Agriculture, Environment and Rural Areas. It was designated in 1982 (date of the regulation: March 25, 1982). The nature reserve replaces the nature reserve of the same name designated in 1980.[1] It is part of the FFH area "Alster system to Itzstedter See and Nienwohlder Moor" and the EU bird sanctuary "Alsterniederung". To the south, it borders the "Nienwohld" landscape protection area. The responsible lower nature conservation authorities are the districts of Stormarn and Segeberg.
