The Bornrieth Moor ( German : Bornriethmoor ) is the remains of a raised bog in the German district of Celle and belongs to the Südheide Nature Park . It has an area of 115 hectares (280 acres). The bog, which has had most of its peat extracted, was reflooded and placed under nature conservation protection in 1988. The moor was also designated as a Special Area of Conservation . The responsible nature conservation authority is the district of Celle. The area is out-of-bounds to the public. Several cranes have turned up here again and are breeding. The otherwise rare bog myrtle ( Myrica gale ) is common here. Much of the moor is covered by the common reed ('Phragmites'). Bog asphodel (Narthecium ossifragum), cottongrass (Eriophorum) and sundews (Drosera) may also be found here.
8-471: Between 1673 and 1678, boiling houses were built on the edge of the moor for the Sülze Saltworks , because the bogs in the vicinity of Sülze had been exhausted. Two salt houses were constructed here, each with two salt pans and a graduation tower , 200 m long and 7 m high. A boring mill was also built to manufacture water pipes from tree trunks. Peat was delivered by boat along canals excavated for
16-433: Is fed into artificially created ponds from which water is drawn out by evaporation , allowing the salt to be subsequently harvested. The ponds also provide a productive resting and feeding ground for many species of waterbirds , which may include endangered species. However, Ghanaian fisheries scientist RoseEmma Mamaa Entsua-Mensah also noted that salt winning can destroy mangrove forests and mudflats , altering
24-494: The salinity of the pond increases. In low- to mid-salinity ponds, green algae such as Dunaliella salina are predominant, although these algae can also take on an orange hue. Halobacteria , a type of halophilic Archaea (also known as Haloarchaea ), are responsible for changing the color of middle to high-salinity ponds to shades of pink, red, and orange. Other bacteria such as Stichococcus also contribute tints . Notable salt ponds include: Until World War II , salt
32-420: The environment and making it unproductive for other development or fish growth. The ponds are commonly separated by levees . Salt evaporation ponds may also be called salterns , salt works or salt pans . Due to variable algal concentrations, vivid colors (from pale green to bright red) are created in the evaporation ponds. The color indicates the salinity of the ponds. Microorganisms change their hues as
40-466: The moor. This was intended to simulate the nearby airfield at Faßberg and divert attention away from it. 52°46′29″N 10°05′50″E / 52.77472°N 10.09722°E / 52.77472; 10.09722 Salt evaporation pond A salt evaporation pond is a shallow artificial salt pan designed to extract salts from sea water or other brines . The salt pans are shallow and expansive, allowing sunlight to penetrate and reach
48-529: The purpose. The brine was transported in wooden pipes from Sülze. As early as 1719 the first discussions were held about moving the boiling sites again because Bornrieth Moor had been exhausted. In 1723 the new pipeline to the Scheuer Bruch was ready and in 1725 brine was boiled in the newly established village of Altensalzkoth . In the Second World War a dummy airfield was laid out on
56-552: The seawater. Natural salt pans are formed through geologic processes, where evaporating water leaves behind salt deposits. Some salt evaporation ponds are only slightly modified from their natural version, such as the ponds on Great Inagua in the Bahamas , or the ponds in Jasiira, a few kilometres south of Mogadishu , where seawater is trapped and left to evaporate in the sun. During the process of salt winning , seawater or brine
64-463: Was extracted from sea water in a unique way in Egypt near Alexandria . Posts were set out on the salt pans and covered with several feet of sea water. In time the sea water evaporated, leaving the salt behind on the post, where it was easier to harvest. Salt pans are shallow, open, often metal pans used to evaporate brine. They are usually found close to the source of the salt. For example, pans used in
