83-672: The Wormsgraben is a waterway in the Harz Mountains of central Germany in the state of Saxony-Anhalt . The Wormsgraben is located 1 to 3 km west of Drei Annen Hohne and 1 km south of the Hohneklippen rocks. The River Wormke , which empties into the Kalte Bode near Mandelholz  [ de ] (a part of Elend ), is in its upper reaches fed through a weir into the Wormsgraben. Initially most of

166-422: A breeding pair has settled in the eastern Harz as the result of a wildlife reintroduction project. The ring ouzel prefers semi-open stone runs and lightly wooded transition zones between treeless raised bogs and forests . The Harz is home to one of its few, isolated breeding areas in central Europe. Its main distribution area extends across northwest Europe, including large parts of England and Scotland, as well as

249-687: A consequence of the mining industry in the Upper Harz, was largely destroyed by a bark beetle outbreak and a storm of hurricane proportions in November 1800. This largest known bark beetle infestation in the Harz was known as the Große Wurmtrocknis , and destroyed about 30,000 hectares (74,000 acres) of spruce forest and lasted about for 20 years. The woods were largely reforested with spruce. Continuous problems with bark beetle and storms were

332-565: A consequence of this it is also referred to as the "Classic Geological Square Mile" ( Klassischen Quadratmeile der Geologie ). There is a room devoted to geology in the Harz Museum in Wernigerode. The vegetation of the Harz mountains is divided into six altitudinal zones : From the edge of the Harz to 700 m above sea level beech woods dominate, especially the wood-rush beech woods on locations poorly supplied with nutrients where

415-543: A cross-section of 1.5 m² at a level of 416.60 m above sea level (Normalnull). Each pipe can push 10-15 m3 /s of water, making the spillway capacity roughly 120 m3 /s. Valves are also equipped to the pipes which can reduce the siphon effect in the case that is needed. The hydro-electric power station in Romkerhalle is fed via a pipe from the Oker Reservoir and has a capacity when completed of 4.14 MW. It

498-556: A hill range has lower temperatures and higher levels of precipitation than the surrounding land. The Harz is characterised by regular precipitation throughout the year. Exposed to westerly winds from the Atlantic, heavy with rain, the windward side of the mountains has up to 1,600 mm of rain annually (West Harz, Upper Harz, High Harz); in contrast, the leeward side only receives an average of 600 mm of precipitation per annum (East Harz, Lower Harz, Eastern Harz foothills). The Harz

581-482: A keen interest in science (see Goethes: Wahrheit und Dichtung ). In 1777, Goethe climbed the Brocken, departing from Torfhaus. At that time, there was still no mass tourism on the Brocken; in the year 1779 only 421 walkers were recorded. Goethe described his feelings on the summit later, as follows: So lonely, I say to myself, while looking down at this peak, will it feel to the person, who only wants to open his soul to

664-473: A lack of old trees and natural brooks). Through improvements to its habitat, including the renaturalisation of waterways and the creation of relatively undisturbed peaceful areas, the black stork population has now recovered. A typical mammal of such deciduous woods is the European wildcat ( Felis silvestris ), that has established a stable population in the Harz. It prefers the diverse wooded areas, which offer

747-466: A result of deliberate forest management . Sycamore trees are also found in these woods. Spruce woods thrive in the highest locations from about 800 m to the tree line at around 1,000 m above sea level. These woods are also home to some deciduous trees such as rowan, silver and downy birches ( Betula pendula and Betula pubescens ) and willows ( Salix spec. ). Conditions of high humidity foster an environment rich in mosses and lichens . In spite of

830-416: A result of the increasingly continental climate on the eastern edge of the Harz, the common beech gives way to mixed forests of sessile oak. At intermediate heights of between 700 and 800 m above sea level, mixed woods of spruce ( Picea abies ) and common beech would predominantly be found under natural conditions. However, apart from a few remnants, these were supplanted a long time ago by spruce stands as

913-419: A rich variety of food. The animal kingdom of the mixed beech and spruce woods is also diverse. Species that thrive in mixed forest are especially at home. For example, the mixed mountain forest is the natural habitat of the capercaillie ( Tetrao urogallus ). The Tengmalm's owl ( Aegolius funereus ) may also be found here. It breeds almost exclusively in black woodpecker holes in old beeches, and needs, unlike

996-406: A role. Melic grass beech woods are found in the few places where there is an abundance of nutrients and bases , e. g. over dolerite and gneiss formations, and they have a vegetation layer rich in variety and luxuriant growth. Here, too, the common beech dominates, mixed, for example, with sycamore, ash ( Fraxinus excelsior ), hornbeam ( Carpinus betulus ) and Scots elm ( Ulmus glabra ). As

1079-407: A type of damselfly , can be seen by streams in the Harz. The dipper ( Cinclus cinclus ), which is found everywhere on Harz streams, occurs almost exclusively in the highlands. Its habitat is very fast-flowing, clear mountain streams with wooded banks. It can dive and run under water along the stream bed. It turns stones over in its search for food. The grey wagtail ( Motacilla cinerea ) also uses

1162-532: Is 75 million m³. The hydro-electric power station at Romkerhalle is fed by the Oker Reservoir. The construction of the Oker Dam was begun by Hr. Press in the years 1938 to 1942 and then completed between 1949 and 1956. Its completion became pressing following the devastating floods in Wolfenbüttel and Brunswick in the winter of 1946/47 when there were heavy falls of snow. Before work started

1245-612: Is a dam in the Harz mountains in Lower Saxony , Germany . It is fed by the River Oker . The dam is in the shape of an arch (see arch-gravity dam ). It is 75 m high, 260 m long, can impound up to 47 million m³ of water and provides hydropower , flood protection and water regulation at times of low water . It is also used indirectly for the production of drinking water . Its average annual discharge

1328-681: Is a native of the bilberry-rich bog spruce woods. Only a few animals are able to survive the extreme conditions of the raised bogs . Examples of these are the Alpine emerald dragonfly ( Somatochlora alpestris ), which only occurs in Lower Saxony in the Harz, and is endangered in Germany, and the Subarctic darner ( Aeshna subarctica ), a damselfly which is threatened with extinction. Rocks and stone runs are important habitat components for

1411-479: Is a ski jump bucket basin, it is made of a basin structure with an end still. The stilling basin lies about 3 km below the dam of the Oker Reservoir and about 2 km below the Romkerhalle power station. It is furnished with a gravity dam which has a height of 18 metres. The stilling basin can store up to 204,000 m³ of water and its main purpose is to regulate the water level downstream. There

1494-555: Is especially popular with canoeists . Large and sometimes abrupt changes in water level on the Oker result from the unregulated flow of the power station from here as far as the stilling basin of the Oker Reservoir. The Romkerhalle power station is also called the Oker Hydro-Electric Power Station ( Wasserkraftwerk Oker ). The 7.4 km long Oker-Grane Tunnel, with its intake near Romkerhalle and outlet on

1577-424: Is no power station immediately below the dam wall, however it services several smaller power station on the Oker as far as the northern edge of the Harz. Like the Oker Reservoir, in calm weather conditions, it forms a very smooth water surface which reflects the surrounding countryside very clearly. Because of the sheltered location of the stilling basin, this phenomenon occurs very frequently. In order not to pollute

1660-430: Is the highest (above sea level in Lower Saxony. In addition, during the summer months, numerous, private, unmotorised water craft grace the waters of the reservoir. Swimming and diving are also permitted, apart from certain out-of-bounds areas such as the zone near the dam wall. In winter, when the ice is not thick enough to support weight, ice swimming takes place. There is a circular route, using roads and paths, around

1743-538: Is the most geologically diverse of the German Mittelgebirge , although it is overwhelmingly dominated by base-poor rocks. The most common rocks lying on the surface are argillaceous shales , slaty ( geschieferte ) greywackes and granite intrusions in the shape of two large igneous rock masses or plutons . The Gießen-Harz surface layer of the Rhenohercynian zone , which is widespread in

1826-477: Is to control the water level and cleanliness of the Oker Reservoir. The dam site was designed as a retention basin (max. 15 m of water at the pre-dam) in order to create a wetland in the Kellwasser valley. Only when there is a very high level of water in the Oker Reservoir are both reservoirs at the same height. The water level in the pre-dam lake can even rise a few decimetres higher. The bottom outlet

1909-459: Is used only for floods and is only opened in case the normal outlet (located below the Windenhaus) is unable to discharge the water through it. It consists of a 1.2 nominal diameter pipe with a screen , an inspection seal, a shutoff valve on the water side, and a piston valve on the airside. It has a maximum output capacity of 15 m³/s. It has a special type of spillway as it utilized

1992-876: The Roßtrappe , could indicate an earlier Celtic occupation of the Harz. The Harzgau itself was first mentioned in a deed by the Emperor, Louis the Pious , from the year 814, in which it was referred to by its High German form, Hartingowe . According to the Fulda annals of 852, the Harzgau was occupied by the Harudes and after whom the Harudengau ( Harudorum pagus ) was named. Harud , from which Hard , Hart and Harz are derived, means forest or forested mountains, and

2075-678: The Fichtel Mountains and Rhenish Massif . They were, however, heavily eroded due to their height (up to 4 km) and were later covered over by Mesozoic rocks. From the Early Cretaceous and into Late Cretaceous times the Harz was uplifted in a single block by tectonic movements and, particularly during the Tertiary period, the younger overlying strata were eroded and the underlying base rock left standing as low mountains. The most important uplift movements were during

2158-674: The Inner German border ran through the Harz, the west belonging to the Federal Republic of Germany (West Germany) and the east to the German Democratic Republic (East Germany). Today the Harz forms a popular tourist destination for summer hiking as well as winter sports. About 700,000 to 350,000 years ago Homo erectus hunted in and around the Harz near Bilzingsleben (Thuringia), Hildesheim and Schöningen (Lower Saxony). The Neanderthals entered

2241-542: The Sauerland in west Germany. For the same reason it is also known as the " Vierwaldstättersee of the Harz". From the beginning of March to the beginning of January a passenger boat plies the reservoir ferrying tourists (only at weekends during the off-peak seasons). The large tour on the MS Aquamarin takes approximately 1.5 hours and can be started from all landing stages around the reservoir. This boat service

2324-588: The Wolkenhäuschen ("Little House in the Clouds") on the Brocken. As a young man, the famous German poet, Goethe visited the Harz several times and had a number of important lifetime experiences. These included his walks on the Brocken and his visit to the mines in Rammelsberg. Later, his observations of the rocks on the Brocken led to his geological research. His first visit to the Harz awakened in him

2407-528: The common beech ( Fagus sylvatica ) is often the only tree species. In lower, drier locations the English oak ( Quercus robur ) and sessile oak ( Quercus petraea ) occur as well. Sycamore trees ( Acer pseudoplatanus ) may be found growing in wetter places. During times of decay and rejuvenation when there is plenty of light, light-dependent pioneers such as rowan ( Sorbus aucuparia ), silver birch ( Betula pendula ) and pussy willow ( Salix caprea ) play

2490-434: The peregrine falcon ( Falco peregrinus ) and ring ouzel ( Turdus torquatus ). The peregrine, which is threatened with extinction here, needs steep rock outcrops with little vegetation. After its population had died out in the Harz, a breeding pair was re-established in the region. A crucial contribution has been made by extensive efforts to promote quiet areas in the ancestral breeding grounds of this shy species. Since 1980,

2573-487: The pygmy owl ( Glaucidium passerinum ) which is threatened with extinction and which lives in the submontane to subalpine zones within mixed and pine forests interspersed with open areas. They prefer spruce woods for breeding, but feed in more open stands of trees or on open moorland. Like the black stork , the pygmy owl had long since disappeared from the Harz, but returned in the 1980s of its own volition, as its ancestral homeland once again became more natural, so that there

2656-417: The siphon effect . In case of overflow, the water reaches the level of the spillway and starts to discharge and continues to discharge after the water goes a bit lower. This has the advantage of being more sensitive to water rising with higher discharge. This spillway has only been used twice, once in 1981 and another in 1994. The spillway consists of two groups of 2 groups of 4 pipes each, each pipe has

2739-527: The Bode in the northern Harz Foreland. Due to a steep gradient and high rate of flow a high (up to 1 m) and wide embankment is needed on the downhill side of the channel.

2822-491: The Brocken without special permission, and the lighting of fires was forbidden. The first attempts at forest conservation in the Harz were centred on the Brocken, and began with a far-sighted nature conservation act over 275 years ago. In 1718, Count Christian Ernest of the House of Stolberg issued an ordinance in which destruction or damage to the forest on the Brocken would be severely punished. In 1736, Christian Ernest also built

2905-648: The Harudes were the residents or dwellers in the Harud. Of more recent origin are settlements whose names end in –rode , a suffix that is first discernable in the Harzgau from the mid-9th century. Where the founders of these villages came from is unknown. Charlemagne declared the Harz a restricted imperial forest or Reichsbannwald . The Saxon Mirror ( Sachsenspiegel ), the oldest German law book ( Rechtsbuch ), probably published around 1220/30 at Falkenstein Castle in

2988-409: The Harz are some of the best preserved in central Europe. They were formed at the end of the last ice age about 10,000 years ago. A significant proportion of the vegetation on these raised bogs is made up of peat mosses ( Sphagnum spec. ). The flarks ( Schlenken ) and the hummocks ( Bulten ) are home to different species of flora. In the flarks, for example, Sphagnum cuspidatum is found, whereas

3071-475: The Harz is one of the regions of Germany that experiences the most rainfall, its water power was used from early times. Today the dams are primarily used to generate electricity , to provide drinking water , to prevent flooding and to supply water in times of scarcity. Modern dam-building began in the Harz with the construction of the Söse Valley Dam , which was built between 1928 and 1931. The dams of

3154-463: The Harz point to the use of this prehistoric adhesive by Neanderthals about 50,000 years ago. The Upper Palaeolithic Revolution , about 40,000 years ago, saw Homo sapiens move from Africa into Europe, including to the Harz region, where they appear to have ousted the Neanderthals and subsequently settled here. Many discoveries in the Harz, such as the bronze club of Thale, which was found by

3237-793: The Harz rocks is displayed on the Jordanshöhe near Sankt Andreasberg near the car park (see photo). The formation and geological folding of the Harz hills began during a prominent phase of the Palaeozoic era, in the course of the Hercynian mountain building of the Carboniferous period , about 350 to 250 million years ago. At that time in the history of the Earth , numerous high mountains appeared in Western Europe, including

3320-609: The Harz, consists mainly of flysch . Well-known and economically important are the limestone deposits around Elbingerode and the Gabbro of Bad Harzburg . The landscapes of the Harz are characterised by steep mountain ridges, stone runs , relatively flat plateaus with many raised bogs and long, narrow V-shaped valleys , of which the Bode Gorge , the Oker and Selke valleys are the best known. A representative cross-section of all

3403-672: The Harz: Goslar and Göttingen in the west, Harz and Mansfeld-Südharz in the north and east, and Nordhausen in the south. The districts of the Upper Harz are Goslar and Göttingen (both in Lower Saxony), whilst the Lower Harz is on the territory of Harz and Mansfeld-Südharz districts (both in Saxony-Anhalt). The Upper Harz is generally higher and features fir forests, whilst the Lower Harz gradually descends into

Between the pre-dam and the primary dam there is a fully metalled circular path, which is used by cyclists , inline skaters and roller skiers . Only the path between the pre-dam and Altenau, which is barred to motor vehicles, is not metalled, but is surfaced with gravel and stone. On the B 498 in summer there is heavy motorcycle traffic (on

3569-1010: The Oker. The Hassel , the Selke and the Holtemme (whose main tributary is the Zillierbach ) flow into the Bode. The Wipper is fed by the Eine . The Rhume is joined by the Söse and the Oder; the latter being fed by the Sieber . The Zorge , the Wieda and the Uffe all flow into the Helme. → See List of hills in the Harz → See List of rock formations (crags, tors, etc.) in the Harz Climatically

3652-533: The Selke valley, later made the imperial restriction clear: "Whoever rides through the Harz Forest, must unstring his bow and crossbow and keep dogs on a line – only crowned royalty ( gekrönte Häupter ) are allowed to hunt here". Eike von Repkow's Sachsenspiegel which, for centuries, formed the basis on which German law was administered, described the Harz as a place where wild animals are guaranteed protection in

3735-837: The Upper Harz lakes are some of the oldest dams in Germany that are still in operation. → See List of dams in the Harz The largest rivers in the Harz are the Innerste , the Oker and the Bode in the north; the Wipper in the east; and the Oder in the south. The Innerste merges into the Leine and its tributaries are the Nette and the Grane . The rivers Radau , Ecker and Ilse all discharge into

3818-546: The animals in these streams need to be well suited to high velocities. Only a few species, such as fish, swim actively against the stream. The most common species are brown trout ( Salmon trutta forma fario ) and bullhead ( Cottus gobio ). Much richer in variety, by contrast, is the range of species in the system of crevices under the streambed. In addition to the insects and fish hatchlings that thrive here, may be found protozoons , flatworms ( Turbellaria ) and water mites ( Hygrobatoidea ). Other species of animals cling fast to

3901-430: The beech woods, with their abundance of dead wood, are the black woodpecker ( Dryocopus martius ) and stock dove ( Columba oenas ). An indication of the natural state of the beech woods in the Harz is the return of the black stork ( Ciconia nigra ). This shy and susceptible resident of richly diverse deciduous and mixed forest has become very rare in central Europe due to increasing disturbance of its habitat (caused by

3984-486: The common beech gives way to hardier deciduous species such as sycamore, large-leaved lime ( Tilia platyphyllos ), Scots elm or ash. The herbaceous layer is similar to that of the better-nourished beech woods. Notable species amongst the plant communities here include the Alpine blue-sow-thistle ( Cicerbita alpina ), perennial honesty ( Lunaria rediviva ), hard shield fern ( Polystichum aculeatum ) and long beech fern ( Phegopteris connectilis ). The raised bogs in

4067-430: The drier hummocks and occasionally the cross-leaved heath ( Erica tetralix ) may be found. Typical grasses are the sheathed cottongrass ( Eriophorum vaginatum ), known for its bright, white clusters of fruit and deergrass ( Scirpus cespitosus ), which is rust-red in the autumn. One fascinating moorland plant is the round-leaved sundew ( Drosera rotundifolia ). Bog or northern bilberry (Vaccinium uliginosum) grows on

4150-491: The drier margins of the bog. A multitude of wild animals live in the beech forests of the Harz Mountains. Over 5,000 species, most of them insects, have their home in these woods. They include many species that help to decompose leaves and work them into the soil and ground cover, including springtails , oribatid mites , woodlice , roundworms , millipedes , earthworms and snails . Characteristic breeding birds in

4233-505: The earlier, serious destruction of the cave's features by Vandals . The first Harz 'rangers' were formed. In 1705, the last bear was killed in the Harz, on the Brocken. The steadily increasing consumption of wood by the pits and smelting works led to overexploitation of the forests and, from about 1700, to their outright destruction. There were no less than 30,000 charcoal piles in the Harz. In 1707, an order by Count Ernst of Stolberg forbade Brocken guides to take strangers or local folk to

4316-571: The eastern shore of the Grane Reservoir , conducts water from the Oker Reservoir (power station or bottom outlet) into the Grane Reservoir where it can be purified for use as drinking water. The Grane Reservoir itself only has a relatively small catchment area and is reliant on other tributaries in order to be able to supply drinking water. The Oker-Grane Tunnel was built in the period from 1968 to 1970. The stilling basin at Oker Dam

4399-598: The far east, the mountains merge into the East Harz foothills (Harz district, Saxony-Anhalt), which are dominated by the Selke Valley. Part of the south Harz lies in the Thuringian district of Nordhausen. The Harz National Park is located in the Harz; the protected area covers the Brocken and surrounding wilderness area. Approximately 600,000 people live in towns and villages of the Harz Mountains. Because of

4482-598: The heavy rainfall in the region the rivers of the Harz Mountains were dammed from an early date. Examples of such masonry dams are the two largest: the Oker Dam and the Rappbode Dam . The clear, cool water of the mountain streams was also dammed by early mountain folk to form the various mountain ponds of the Upper Harz waterways, such as the Oderteich . The 17 dams in the Harz block a total of twelve rivers. Because

4565-401: The high mountains of southern and eastern Europe. The waterways, with their distinct mountain stream character, play an important role right across the Harz. In comparison with the other natural regions of Lower Saxony, they are still very natural and varied, and the water is very clean. As a result of the high water velocity of the Harz streams, flowers rarely gain a foothold in the water. Even

4648-476: The higher regions are, as in most of the Harz, comparatively poor in nutrients and bases, so that only a few herbaceous plants occur here, such as heath bedstraw ( Galium saxatile ). For that reason it is more the ferns, mosses, lichens and fungi that, in addition to spruce trees, characterise these woods. Boulders and stone runs occur in the areas of weather-resistant rock in the high (alti-)montane and montane zones – these are extreme habitats for vegetation. Due to

4731-424: The hills lie the Cretaceous layers of the sub-Hercynian depression in the rolling hills of the Harz Foreland; south of the Harz, Permian sediments lie flat on southwest-dipping Palaeozoic beds. As a result of the northern fault zone and the vertical or, sometimes even overfolded, geological strata, the geology of the Harz sometimes changes frequently within a relatively small area of just a few square kilometres. As

4814-526: The hummocks are preferred by Sphagnum magellanicum . The blanket of peat moss is penetrated by dwarf bushes such as cowberry and blueberry . Bog-rosemary ( Andromeda polifolia ) is a relict of the ice age. Other such ice age plants include the dwarf birch ( Betula nana ) and few-flowered sedge ( Carex pauciflora ). Cranberries ( Vaccinium oxicoccus ) bloom from May to June. The black crowberry ( Empetrum nigrum ) may also be seen amongst those bearing black fruit. Common heather (Calluna vulgaris) grows on

4897-478: The king's restricted forests . There were three restricted forests, so described, in the state of Saxony, where there was no longer unfettered access for everyone. This ban did not last forever. Mining, ironworks, water management, increasing settlement, woodland clearances, cattle driving, agriculture, and later tourism all undermined this imperial protection over the centuries. As early as 1224, monks who had settled in Walkenried bought extensive tracts of forest in

They have an especially high variety of trees and allow more room of light-loving species such as silver birch, rowan, sycamore, willow and dwarf bushes such as the blueberry ( Vaccinium myrtillus ). Mosses and ferns are also common here. One unusual species is the Carpathian birch ( Betula pubescens subsp. carpatica ). Bog-spruce woods are found around

A well developed ground vegetation thrives on their moderately rocky and fresh, but certainly not wet, soils, characterised in appearance especially by grasses such as shaggy wood-reed ( Calamagrostis villosa ) and wavy hair-grass ( Avenella flexuosa ). The soils in

5229-443: The negative side effects of mining in the Harz Mountains. In 1818, a mounted forester, Spellerberg, from Lautenthal, killed the last lynx in the Harz on the Teufelsberg. At the start of the 19th century, the increasing changes to the natural landscape wrought by man and the extinction of large mammals like the bear, wolf and lynx raised awareness of the threat to nature.

In very calm conditions (no wind or precipitation and no man-made disturbances) a very flat surface forms on the reservoir which mirrors clearly the surrounding landscape. The pre-dam ( Vorsperre ) of the Oker Reservoir is of the gravity dam type, with a height of 20.0 metres. The pre-dam can impound up to 520,000 m³ of water and its primary purpose

It occupies an area of 2,226 square kilometres (859 sq mi), and is divided into the Upper Harz ( Oberharz ) in the northwest, which is up to 800 m high, apart from the 1,100 m high Brocken massif, and the Lower Harz ( Unterharz ) in the east which is up to around 400 m high and whose plateaus are capable of supporting arable farming. The following districts ( Kreise ) fall wholly or partly within

5478-427: The oldest, first, deepest feelings of truth. On 23 March 1798, the last wolf was killed in the Harz near the Plessenburg. The count's guest house on the Heinrichshöhe had become too small and suffered from overcrowding; in 1799 it burned down. In 1800, a new guest house was built on the Brocken to replace it. Around 1800, large swathes of the Harz were deforested. The less resistant spruce monoculture, that arose as

5561-739: The raised bogs on marshy and boggy soils. In these sorts of places spruce woods can, in exceptional cases, also form the natural woodland in lower down the mountains. These wet, moorland woods have a high proportion of peat mosses ( Sphagnum spec. ). The ground vegetation may also have a rich proliferation of low bushes such as cowberry ( Vaccinium vitis-idaea ). Clumps of purple moor grass ( Molinia caerulea ) are also typical of this type of woodland habitat. The characteristic species of fungi in natural spruce woods are Phellinus viticola and prunes and custard ( Tricholomopsis decora ). Ravine ( Schluchtwald ), riparian ( Auwald ) and river source ( Quellwald ) woods only occur in small areas. In these places

5644-415: The rich food supplies of the mountain brooks. In 2000, the lynx was successfully reintroduced by the Harz National Park , and it has since fitted well into the ecology of the region. Through specific conservation measures in past years, the retreat of the bat population in the Harz has been halted. Amongst the mammals that may be hunted are the red deer , roe deer , wild boar and mouflon . The Harz

After the Wormsgraben is crossed by the Glashütten Way ( Glashüttenweg i.e. Glassworks Way) at the Sandgrube, it discharges into the Zillierbach near the forest lodge of Hohne. The artificial ditch drains the water of the Bode and leads it to the catchment area of the Zillierbach- Holtemme , in order to transfer it after 48 km to

5810-408: The silver mining industry in the Upper Harz and in Goslar. In the middle of the 14th century, the settlements in the Harz became heavily depopulated as a result of the Black Death , and a systematic resettlement of mining villages in the Upper Harz did not take place until the first half of the 16th century. In 1588, the Nordhausen doctor, Johannes Thal, published the first book on regional flora in

5893-406: The small hamlet of Schulenberg in the valley had to be abandoned; it was rebuilt above the reservoir. The Oker Reservoir lies alongside the B 498 federal road, that follows the course of the River Oker between Goslar and Altenau. On the east bank is a forest road, that is out of bounds to private vehicles. With its many side arms the Oker Reservoir resembles the much larger Bigge Reservoir in

5976-660: The spruce woods, more open beech forest with its higher population of small mammals in its search for food. For cover, however, it prefers the darker, denser spruce trees. A large number of the animals that live in natural spruce forest are suited to the special conditions of life in the higher parts of the Harz. Typical residents amongst the bird population include the crested tit ( Parus cristatus ), goldcrest and firecrest ( Regulus regulus and Regulus ignicapillus ), siskin ( Carduelis spinus ), treecreeper ( Certhia familiaris ), coal tit ( Parus ater ) and crossbill ( Loxia curvirostra ). Special mention should be made here of

6059-529: The stage about 250,000 years ago and hunted aurochs , bison , brown bear and cave bear , mammoths , rhinos , horses , reindeer , forest elephants and other animals in the Harz region. Tools used by Neanderthals were discovered inter alia in the Einhorn Cave in the southern Harz (100,000 years ago) and in the Rübeland Caves. Finds of birch pitch near Aschersleben on the northern edge of

6142-494: The stones, e. g. caddis fly larvae ( Trichoptera ) and snails , or can only live in the reduced water velocities on the bed of the stream or on stones by having flat body shapes, e. g. stonefly larvae. In the calmer parts of the stream, behind stones or in blankets of moss, there are also water beetles ( Hydrophilidae ) and small shrimp-like amphipods . Occasionally the golden-ringed dragonfly ( Cordulegaster boltoni ) and beautiful demoiselle ( Calopteryx virgo ),

6225-493: The sub-Hercynian phase (83  mya ), when the northern edge was steeply tilted. This formed a fault zone on the northern border of the Harz (the Northern Harz Boundary Fault or Harznordrandverwerfung ). The Harz is a fault-block range, that rises abruptly from the surrounding lowlands in the west and northeast and gradually dips towards the south. It is dissected by numerous deep valleys. North of

6308-543: The surrounding area and has deciduous forests interspersed with meadows. The dividing line between Upper and Lower Harz follows approximately a line from Ilsenburg to Bad Lauterberg , which roughly separates the catchment areas for the Weser (Upper Harz) and Elbe (Lower Harz). Only on the southeastern perimeter of the Upper Harz, which is also called the High Harz ( Hochharz ) (Goslar, Göttingen and Harz districts), does

6391-500: The town of Goslar , and mines became established in the following centuries throughout the mountains. During the Middle Ages , ore from this region was exported along trade routes to far-flung places, such as Mesopotamia . The wealth of the region declined after these mines became exhausted in the early 19th century. People abandoned the towns for a short time, but prosperity eventually returned with tourism. Between 1945 and 1990,

6474-466: The western Harz, to secure economically the one quarter of the Rammelsberg ore profits promised to them by Frederick Barbarossa in 1129. From that it can be deduced that there was already a shortage of wood then. From the 12th to the 14th centuries, large parts of the Harz were managed economically by the Cistercian Abbey of Walkenried . As well as agriculture and fishing, they also controlled

6557-520: The world, Silva hercynia , in which he described the flowers specific to the Harz. In 1668, Rudolph Augustus, Duke of Brunswick-Lüneburg granted the first conservation order for Baumann's Cave . The ducal decree stated, inter alia , that the cave should be permanently preserved by all those responsible as a special, natural wonder. It also stated that nothing should be spoiled or destroyed, and that groups of ordinary strangers should not be allowed to enter without prior arrangement. A resident mine worker

6640-437: Was entrusted to oversee the natural monument . Until the issue of this conservation order, there had only been an order for the protection of the forest, which had been issued by the ruling princes for real, practical considerations. But for the first time the 1668 cave order took ethical-aesthetic considerations into account. The year 1668 was the birth of classic nature conservation in the Harz. The order had been precipitated by

6723-486: Was first mentioned as Hartingowe in an 814 deed by the Carolingian King Louis the Pious . Settlement within the mountains began only 1000 years ago, as in ancient times dense forests made the region almost inaccessible. The suffix -rode (from German : roden , to stub) denotes a place where woodland had been cleared to develop a settlement. The year 968 saw the discovery of silver deposits near

6806-415: Was opened in 1956 and is equipped with a single Francis turbine . It has a descent of 80 m, the nominal discharge is 6.5 m³ per second and it generates 12.5 million kWh per year. The power station is operated as a peaking power plant working for about 8 hours per day. It discharges directly into the river bed of the Oker. At this point the whitewater section of the Oker begins and

6889-525: Was sufficient food to support it (insects, small mammals and small birds) as well as standing dead wood (spruce trees with woodpecker holes). In addition to the many species of birds, there is a range of large butterflies in the various spruce woods that, outside of the Harz, are seriously endangered or simply non-existent. Two species will be mentioned here as examples. Gnophos sordarius occurs in old, open wood-reed spruce forest, sometimes in connection with stone runs or bog spruce forests; Enthephria caesiata
