The Bullenkuhle is a predominantly marshy lake in the extreme north of the district of Gifhorn in the north German state of Lower Saxony . This strange biotope and geotope has been formed into a natural hollow in the terrain that is termed a sinkhole . The area is environmentally protected.

29-555: The Bullenkuhle lies about 15 kilometres south of the town of Uelzen and a good kilometre west of the village of Bokel (in the municipality of Sprakensehl ) at the edge of a large pine forest at a height of about 95 metres (312 ft) above NN. A stream emerges in the immediate vicinity which is initially called the Bokeler Bach and, later, becomes the Aue and finally, after combining with other streams, becomes an Elbe tributary,

58-429: A depth of several hundred metres can result in the ground collapsing right up to the surface. This results in prominent, often steep-sided and deep hollows called sinkholes or dolines (although dolines can have other morphogenetic causes, particularly in karst regions). Many of these funnel-shaped hollows remain dry, in others water collects that can later become marshy. Sinkholes are geologically often very recent; it

87-522: A diameter of about 130 metres (430 ft) and attains a depth of 15 metres (49 ft). Exactly when the Bullenkuhle was formed is not known. This would need a stratigraphic investigation and pollen analysis of the vertical profile of the sinkhole (see Maujahn Moor ). The visitor to the Bullenkuhle comes across a basin-shaped hollow with steep sides of 30 to 60° in places. At the foot of

116-659: A small role in the Hanseatic League, there is evidence that it traded with Livonia and Spain . At the Schnellenmarket , a London trading office purchased Uelzener linen , earthenware pitchers were offered for sale and brewery business flourished.

On average, there are 11 days with a maximum temperature of over 30 °C (86 °F) per year, and high temperatures of over 35 °C (95 °F) occur every four years on average.

Uelzen is characterised by timber-framed architecture and also has some striking examples of North German brick Gothic . The town earned pan-regional fame when Friedensreich Hundertwasser was selected to redesign

203-412: Is a waterbody in the middle of a raised or kettle bog , formerly also in percolating mires ( Durchströmungsmooren ). It is also called a bog pool , bog eye , raised bog kolk , bog kolk or just kolk . Bog ponds owe their existence to the growth of the bog body and are thus of biogenic origin. Brown bog ponds are surrounded by peat and receive their water exclusively from precipitation or from

232-499: Is also noteworthy and some species are peculiar to marsh biotopes . In particular there are up to eight species of amphibian as well as adders . 52°48′47″N 10°31′01″E  /  52.81306°N 10.51694°E  / 52.81306; 10.51694 Uelzen Uelzen ( German: [ˈʏltsn̩] ; Low German : Ülz'n ), officially the Hanseatic Town of Uelzen (German: Hansestadt Uelzen ),

261-1150: Is not uncommon for them to be only a few thousand years old and many hollows only date back a few hundred years. Examples of sinkhole lakes and marshes include very large lakes like the Arendsee and the Zwischenahner Meer – both at least 500 hectares in area – the Seeburger See , the Sager Meer in Oldenburg district , the Rudower See in Westprignitz district or the "bottomless marsh" ( Grundloses Moor ) in Soltau-Fallingbostel district and Maujahn in Lüchow-Dannenberg district . The Bullenkuhle belongs to this group, albeit considerably smaller. This sinkhole has

319-438: Is there stretch of open water about 0.1 hectares (0.25 acres) in area and several metres deep; a so-called bog pond . With an electrolytic conductivity of 24 μS/cm this wetland is very oligotrophic , it is rich in humus and, with a pH value of 5.0, moderately acidic. It is populated by typical marsh plants like peat mosses , bladderworts and the rare Dwarf White Water Lily ( Nymphaea candida ). In addition to peat mosses,

377-690: The River Ilmenau . The area belongs to the southeast fringes of the Hohen Heide in the centre of the Lüneburg Heath . This landscape formed from end and ground moraines and periglacial sediments was created geomorphologically mainly by the edges of the ice sheet during the later phases of the Saalian glaciation , i.e. during the so-called Drenthe II stage and the final glacial advance of

406-427: The floating mat pressing in on the bog pond consists mainly of Hare's-tail Cottongrass , Cross-leaved Heath , Common Heather and Crowberry ; as well as White Beak-sedge and Cranberry . The largely unwooded terrain can be described as flat to slightly rounded intermediate marsh ( Zwischenmoor ). On its periphery is a ring-shaped bog, which is slightly better supplied with nutrients from precipitation running down

435-637: The Lüneburg Heath is maritime temperate . In north Germany there are numerous salt domes under the ground – relicts of the Zechstein Sea from the Permian period, which were later relocated and deformed tectonically . When rock salt comes into contact with ground water it leaches away; i.e. the salt is absorbed by the water and transported off. This can lead to the development of large caverns that finally cave in. Sometimes such an event at

The typical open heath landscape of the Lüneburg Heath - which arose anthropogenically through overexploitation of forests, burning, plaggen cutting and grazing - only exists today in fragments in the area around the Bullenkuhle.

638-648: The large rain storage capacity of raised bogs. Such kolks generally represent the non-evaporating excess water of a bog. The central waterbody of these bogs exhibit almost no sedimentation . The accumulation of nutrients can lead to the formation of floating mats . Their vegetation differs from that of other structures in the bog. Usually the edges of the kolk are more nutrient-rich as a result of mineralisation processes caused by wave and wind action. Here woody plants, such as downy birch ( Betula pubescens ), and other species of plant, e.g. purple moor grass ( Molinia caerulea ), may establish, that otherwise are missing on

667-471: The railway station: the final work of the celebrated Viennese artist and architect was ceremonially opened in 2000 as the Hundertwasser Station, Uelzen , and remains a popular tourism destination.

696-405: The slopes of glacial sands is a marsh covering about 0.5 hectares (1.2 acres) that on closer inspection turns out to be a 'quaking bog' ( Schwingrasen or Schwingmoor ) - a floating mat of moss and other plants, under which there is presumably no homogeneous layer of peat, but at least in places just a body of water. The floating mat covers at least 80% of the wetland or marsh, only in the northeast

725-475: The slopes than the centre of the marsh. Bottle Sedge reeds thrive particularly well here. The slopes of the funnel-shaped terrain are covered with low vegetation such as Common Heather, Bilberry , and Cranberry , and also with Purple Moor Grass and trees. The latter include several very large and old Juniper bushes and trees, especially conspicuous and typical of the terrain. Other varieties include birch trees, Buckthorn bushes and pines.
