110-1245: Ulmus glabra Hudson , the wych elm or Scots elm , has the widest range of the European elm species, from Ireland eastwards to the Ural Mountains , and from the Arctic Circle south to the mountains of the Peloponnese and Sicily , where the species reaches its southern limit in Europe; it is also found in Iran. A large deciduous tree, it is essentially a montane species, growing at elevations up to 1,500 m (4,900 ft), preferring sites with moist soils and high humidity. The tree can form pure forests in Scandinavia and occurs as far north as latitude 67°N at Beiarn Municipality in Norway. It has been successfully introduced as far north as Tromsø and Alta in northern Norway (70°N). It has also been successfully introduced to Narsarsuaq , near

As merchants from the Middle East traded with the Bashkirs and other people living on the western slopes of the Ural as far north as Great Perm , since the 10th century, medieval mideastern geographers had been aware of the existence of the mountain range in its entirety, stretching as far as the Arctic Ocean in the north. The first Russian mention of

By topography and other natural features, the Urals are divided, from north to south, into the Polar (or Arctic), Nether-Polar (or Sub-Arctic), Northern, Central and Southern parts. The Polar Urals extend for about 385 kilometers (239 mi) from Mount Konstantinov Kamen in the north to the river Khulga in the south; they have an area of about 25,000 km (9,700 sq mi) and
660-510: A hugely variable reaction to Dutch elm disease (DED), including all the fashionable pre-20th century plantsman's clones (see Subspecies and varieties). However, field elm is genetically highly variable; Italian specimens when inoculated with the pathogen displayed between 15 and 100% dieback and between 70 and 100% wilting, whereas with trees tested in Spain, the variability ranged from 5 to 100% dieback, and 20 to 95% wilting.

Research in Spain has indicated the presence of a triterpene , alnulin , rendering the tree bark less attractive to the beetle than the field elm , though at 87 μg/g dried bark, its concentration is not as effective as in Ulmus laevis (200 μg/g). Moreover, once the tree is dying, its bark is quickly colonized by
2200-914: Is much less developed on the eastern slopes. The eastern slopes are relatively flat, with some hills and rocky outcrops and contain alternating volcanic and sedimentary layers dated to the middle Paleozoic Era. Most high mountains consist of weather-resistant rocks such as quartzite , schist and gabbro that are between 395 and 570 million years old. The river valleys are underlain by limestone. The Ural Mountains contain about 48 species of economically valuable ores and minerals. Eastern regions are rich in chalcopyrite , nickel oxide (e. g. Serov nickel deposit ), gold , platinum , chromite and magnetite ores, as well as in coal ( Chelyabinsk Oblast ), bauxite , talc , fireclay and abrasives. The Western Urals contain deposits of coal, oil, natural gas (Ishimbay and Krasnokamsk areas) and potassium salts . Both slopes are rich in bituminous coal and lignite , and

The word "wych" (also spelled "witch") comes from the Old English wice , meaning pliant or supple, which also gives definition to wicker and weak. Jacob George Strutt 's 1822 book, Sylva Britannica attests that the Wych Elm was sometimes referred to as the "Wych Hazel", a name now applied to the unrelated species Hamamelis , commonly called "wych hazels".

The tallest recorded field elms in Greece were two specimens planted in 1650 beside the newly built church of the Archangels Michael and Gabriel, in Omali Voiou (Oμαλή Bοΐου) near Siatista , which, despite being open-grown trees, attained a height of 40 metres by the mid-20th century. The immemorial elm opposite the village square of Aidona in Thessaly , Greece which has been "listed" as
7480-407: The height of 60–80 centimetres (24–31 in). Much of the land is cultivated. To the south, the meadow steppes become more sparse, dry and low. The steep gravelly slopes of the mountains and hills of the eastern slopes of the Southern Urals are mostly covered with rocky steppes. River valleys contain willow , poplar and caragana shrubs. Forest landscapes of the Urals are diverse, especially in
7590-490: The highest peaks and plateaus of Northern and Southern Urals are inhabited by some mountainous or tundra avian species, like Golden Plover , Dotterel , Ptarmigan and Willow Grouse , in Polar Urals also by Rough-legged Buzzard and Snowy Owl. The steppes of the Southern Urals are dominated by hares and rodents such as hamsters , susliks , and jerboa . There are many birds of prey such as lesser kestrel and buzzards . The continuous and intensive economic development of
7700-541: The highest peaks of the range: Mount Narodnaya (1,895 m (6,217 ft)), Mount Karpinsky (1,878 m (6,161 ft)) and Manaraga (1,662 m (5,453 ft)). They extend for more than 225 km (140 mi) south to the Shchugor . The many ridges are sawtooth shaped and dissected by river valleys. Both Polar and Nether-Polar Urals are typically Alpine; they bear traces of Pleistocene glaciation, along with permafrost and extensive modern glaciation, including 143 extant glaciers. The Northern Ural consist of
7810-424: The house of the title and is said to have a "...girth that a dozen men could not have spanned..." Forster describes the tree as "...a comrade, bending over the house, strength and adventure in its roots." The wych elm of the novel had pigs' teeth embedded in the trunk by country people long ago and it was said that chewing some of the bark could cure toothache. In keeping with the novel's epigraph, "Only connect...",
7920-405: The largest deposit of bituminous coal is in the north (Pechora field). The specialty of the Urals is precious and semi-precious stones, such as emerald , amethyst , aquamarine , jasper , rhodonite , malachite and diamond . Some of the deposits, such as the magnetite ores at Magnitogorsk , are already nearly depleted. Many rivers originate in the Ural Mountains. The western slopes south of
8030-655: The last centuries has affected the fauna, and wildlife is much diminished around all industrial centers. During World War II, hundreds of factories were evacuated from Western Russia before the German occupation, flooding the Urals with industry. The conservation measures include establishing national wildlife parks. There are nine strict nature reserves in the Urals: the Ilmen , the oldest one, mineralogical reserve founded in 1920 in Chelyabinsk Oblast, Pechora-Ilych in
8140-502: The leaf veins, detectable with the aid of a magnifying glass. The samarae are oval or obovate, glabrous, 12–15 mm ( 15 ⁄ 32 – 19 ⁄ 32 in) long, notched at the top, with the seed close to the notch. Ulmus minor in France generally begins to flower and fruit when aged 10 years. The species readily produces suckers from roots and stumps, even after devastation by Dutch elm disease ; consequently genetic resources are not considered endangered. The species has
8250-589: The main ridges by the Miass . The maximum height is 1,640 m (5,380 ft) ( Mount Yamantau ) and the width reaches 250 km (160 mi). Other notable peaks lie along the Iremel mountain ridge (Bolshoy Iremel and Maly Iremel) and Nurgush . The Southern Urals extend some 550 km (340 mi) up to the sharp westward bend of the river Ural and terminate in the Guberlin Mountains and finally in
8360-717: The main trunk of the Trans-Siberian railway. The highest peak of the Ural, Mount Narodnaya , (elevation 1,895 m [6,217 ft]) was identified in 1927. During the Soviet industrialization in the 1930s, the city of Magnitogorsk was founded in the South-Eastern Ural as a center of iron smelting and steelmaking . During the German invasion of the Soviet Union in 1941–1942, the mountains became
8470-616: The most diverse in composition: here, together with coniferous forests are also abundant broadleaf tree species such as English oak , Norway maple and elm. The Virgin Komi Forests in the northern Urals are recognized as a World Heritage site. The forests of Urals are inhabited by animals typical of Eurosiberia, such as elk, brown bear, fox, wolf, wolverine , lynx , squirrel, Siberian chipmunk , flying squirrel , reindeer and sable (north only). The fauna of Polar Urals also includes species like Arctic Fox and lemmings. Because of
8580-525: The mountain chain into seven major units, each of which has its own typical pattern of mountain ridges. From north to south, these are the Pay-Khoy, Zapolyarnyy, Pripolyarnyy, Polyarnyy, Severnyy, Sredniy, Yuzhnny Ural and Mugodzhary. The average altitudes of the Urals are around 1,000–1,300 m (3,300–4,300 ft), the highest point being Narodnaya peak in the Pripolyarnyy Ural which reaches
8690-498: The mountain slopes and summits of the northern areas. The Central Ural are the lowest part of the Ural, with smooth mountain tops, the highest mountain being 994 m (3,261 ft) (Basegi); they extend south from the river Ufa . The relief of the Southern Ural is more complex, with numerous valleys and parallel ridges directed south-west and meridionally. The range includes the Ilmensky Mountains separated from
8800-437: The mountains and their systematic extraction began in the early 18th century, eventually turning the region into the largest mineral base of Russia. One of the first scientific descriptions of the mountains was published in 1770–71. Over the next century, the region was studied by scientists from a number of countries, including Russia (geologist Alexander Karpinsky , botanist Porfiry Krylov and zoologist Leonid Sabaneyev ),
8910-445: The mountains have contributed significantly to the mineral sector of the Russian economy . The region is one of the largest centres of metallurgy and heavy industry production in Russia. As attested by Sigismund von Herberstein , in the 16th century, Russians called the Ural range by a variety of names derived from the Russian words for rock (stone) and belt. The modern Russian name for the Urals ( Урал , Ural ), first appearing in
9020-750: The mountains to the east of the East European Plain is provided by the Primary Chronicle , where it describes the Novgorodian expedition to the upper reaches of the Pechora in the year 1096. During the next few centuries, the Novgorodians engaged in fur trading with the local population and collected tribute from Yugra and Great Perm , slowly expanding southwards. The city-state of Novgorod established two trade routes to
9130-469: The north and its suckering habits, continental U. minor was occasionally planted as an ornamental urban tree. Augustine Henry wrote in 1913 that the U. minor planted in parks in Scotland were of French origin. More recently U. minor seed was imported to the UK from Italy. There are mature survivors in Edinburgh that are not the common U. minor cultivars (2015). U. minor has been introduced to
9240-411: The north, and readily hybridizes with it to produce the so-called 'Dutch elm' Ulmus × hollandica . In Spain and Italy Ulmus minor has naturally hybridized with Siberian elm U. pumila . In Spain U. pumila was introduced in the 16th century and has since spread widely, contributing to conservation concerns for U. minor . In Italy U. pumila was introduced in the 1930s; research is ongoing into
9350-430: The other European species, hence the specific epithet minor , however they can vary greatly according to the maturity of the tree. Leaves on juvenile growth (suckers, seedlings etc.) are coarse and pubescent, whereas those on mature growth are generally smooth, though remaining highly variable in form; there are generally fewer than 12 pairs of side veins. A common characteristic is the presence of minute black glands along
9460-632: The point of view of some authors of Classical antiquity, which were popular during the Renaissance . Only after Sigismund von Herberstein in his Notes on Muscovite Affairs (1549) had reported, following Russian sources, that there are mountains behind the Pechora and identified them with the Riphean Mountains and Hyperboreans of ancient authors, did the existence of the Ural, or at least of its northern part, become firmly established in
9570-729: The region. The region served as a military stronghold during Peter the Great 's Great Northern War with Sweden, during Stalin's rule when the Magnitogorsk Metallurgical Complex was built and Russian industry relocated to the Urals during the Nazi advance at the beginning of World War II, and as the center of the Soviet nuclear industry during the Cold War . Extreme levels of air, water, and radiological contamination and pollution by industrial wastes resulted. Population exodus followed, and economic depression at
9680-522: The reign of Peter I of Russia . In 1720–1722, he commissioned Vasily Tatishchev to oversee and develop the mining and smelting works in the Ural. Tatishchev proposed a new copper smelting factory in Yegoshikha , which would eventually become the core of the city of Perm and a new iron smelting factory on the Iset , which would become the largest in the world at the time of construction and give birth to
9790-521: The relatively warm climate resulting in less snow and more evaporation. The mountains contain a number of deep lakes. The eastern slopes of the Southern and Central Urals have most of these, among the largest of which are the Uvildy, Itkul, Turgoyak, and Tavatuy lakes. The lakes found on the western slopes are less numerous and also smaller. Lake Bolshoye Shchuchye, the deepest lake in the Polar Urals,
9900-434: The roots, and any seedlings are often consumed by uncontrolled deer populations, regeneration is very restricted, limited to sprouts from the stumps of young trees. The resultant decline has been extreme, and the wych elm is now uncommon over much of its former range. It is best propagated from seed or by layering stooled stock plants, although softwood cuttings taken in early June will root fairly reliably under mist. Wych elm
10010-470: The sake of his people who then poured a stone pile over his grave, which later turned into the Ural Mountains. Possibilities include Bashkir үр "elevation; upland" and Mansi ур ала "mountain peak, top of the mountain", V.N. Tatischev believes that this oronym is set to "belt" and associates it with the Turkic verb oralu- "gird". I.G. Dobrodomov suggests a transition from Aral to Ural explained on
10120-411: The southern hemisphere, notably Australasia and Argentina. U. minor can live to a great age. An ancient field elm stood until recently in the village square of Metaxades , Thrace , Greece. Having abandoned their original village in 1286 after cholera outbreaks, the villagers re-founded it in the hills where a young elm was growing beside a spring. An elm (reputedly the original) and the fountain were
10230-439: The southern part. The western areas are dominated by dark coniferous taiga forests which change to mixed and deciduous forests in the south. The eastern mountain slopes have light coniferous taiga forests. The Northern Urals are dominated by conifers, namely Siberian fir , Siberian pine , Scots pine , Siberian spruce , Norway spruce and Siberian larch , as well as by silver and downy birches . The forests are much sparser in
10340-588: The southern tip of Greenland ( 61°N ). The tree was by far the most common elm in the north and west of the British Isles and is now acknowledged as the only indisputably British native elm species. Owing to its former abundance in Scotland, the tree is occasionally known as the Scotch or Scots elm; Loch Lomond is said to be a corruption of the Gaelic Lac Leaman interpreted by some as 'Lake of
10450-457: The species in France, including Paris . U. minor in general and a number of clones in particular (see 'Cultivars' below) were once commonly cultivated across Europe in town and country, but owing to its susceptibility to Dutch elm disease, U. minor is now uncommon in cultivation. However, in an ongoing project that began in the 1990s, several thousand surviving field elms have been tested for innate resistance by national research institutes in
10560-638: The summer: the winter is dry because of the Siberian High . The landscapes of the Urals vary with both latitude and longitude and are dominated by forests and steppes. The southern area of the Mughalzhar Hills is a semidesert. Steppes lie mostly in the southern and especially south-eastern Urals. Meadow steppes have developed on the lower parts of mountain slopes and are covered with zigzag and mountain clovers , Serratula gmelinii , dropwort , meadow-grass and Bromus inermis , reaching
10670-408: The time of the collapse of the Soviet Union, but in post-Soviet times additional mineral exploration, particularly in the northern Urals, has been productive and the region has attracted industrial investment. Ulmus minor Ulmus minor Mill. , the field elm , is by far the most polymorphic of the European species, although its taxonomy remains a matter of contention. Its natural range
10780-528: The time of writing, it was "not possible to present an overall breakdown of the European Field Elm into regional varieties". The epithet 'red' elm was commonly used by British foresters, an allusion to the colour of the timber. Richens sank a number of British elms, notably English elm , as either subspecies or varieties of U. minor in 1968. However, Melville , writing ten years later, identified five distinct species (including U. glabra in
10890-791: The tree already in existence. The UK Champion listed in the Tree Register of the British Isles was at Brahan in the Scottish Highlands (died 2021); it had a girth of 703 cm (2.23 m DBH) and a height of 24 m. Possibly the oldest specimen in England was found in 2018 in a field north of Hopton Castle in Shropshire. Coppiced long ago, its bole girth measured 6.3 m in 2018. The oldest specimen in Edinburgh
11000-561: The tree was found to have a slight to moderate susceptibility to elm yellows , and a high susceptibility to the elm leaf beetle Xanthogaleruca luteola . The wych elm is moderately shade-tolerant, but requires deep, rich soils as typically found along river valleys. The species is intolerant of acid soils and flooding, as it is of prolonged drought. Although rarely used as a street tree owing to its shape, it can be surprisingly tolerant of urban air pollution, constricted growing conditions, and severe pollarding. As wych elm does not sucker from
11110-612: The upper slopes of Mount Šimonka in Slovakia , but they are believed to have survived courtesy of their isolation from disease-carrying beetles rather than any innate resistance; 50 clones of these trees were presented to the Prince of Wales for planting at his Highgrove Estate , and at Clapham , Yorkshire . E. M. Forster cites a particular wych elm, one that grew at his childhood home of Rooks Nest, Stevenage , Hertfordshire , 16 times in his novel Howards End . This tree overhangs
11220-647: The village of Samuilovo , 7 km from Sliven. In France, a tree reputedly over 650 years old survived in the centre of Biscarrosse south of Bordeaux until the summer of 2010, when it finally succumbed to Dutch elm disease. Another veteran with a 6-metre girth survives at Bettange , France, close to the Belgian border, reputedly planted in 1593. Other wrecks include 'l'ormeau de Sully' in Villesèquelande near Carcassonne , "a magnificent tree supported by three metal props", said to have been planted in
11330-517: The wide Mughalzhar Hills . The Urals are among the world's oldest extant mountain ranges . Some have estimated the age to be 250 to 300 million years, the elevation of the mountains is unusually high. They formed during the Uralian orogeny due to the collision of the eastern edge of the supercontinent Laurasia with the young and rheologically weak continent of Kazakhstania , which now underlies much of Kazakhstan and West Siberia west of
11440-413: The wych elm may be seen by some as a symbol of the connection of humans to the earth. Margaret Schlegel, the novel's protagonist, fears that any "....westerly gale might blow the wych elm down and bring the end of all things..." The tree is changed to a chestnut in the 1991 film adaptation of Howards End . About 40 cultivars have been raised, although at least 30 are now probably lost to cultivation as
11550-536: Was accepted, despite the wide source-area claimed for it ("Italy, Spain, Portugal and Algeria"), as U. carpinifolia var. italica Henry , by Krüssman (1984), who included a photograph of a specimen in Gisselfeld Park , Denmark. Bean (1988), however, considered it "a variety of rather dubious standing", and it was ignored by Richens (1983). U. canescens Melville and U. boissieri Grudz. were both sunk as U. minor by Richens. The former
11660-516: Was built across the Ural from Solikamsk to the valley of the Tura , where the town of Verkhoturye (Upper Tura) was founded in 1598. Customs was established in Verkhoturye shortly thereafter and the road was made the only legal connection between European Russia and Siberia for a long time. In 1648, the town of Kungur was founded at the western foothills of the Middle Ural. During the 17th century,
11770-430: Was completed in 1763 and rendered Babinov's road obsolete. In 1745, gold was discovered in the Ural at Beryozovskoye and later at other deposits. It has been mined since 1747. The first ample geographic survey of the Ural Mountains was completed in the early 18th century by the Russian historian and geographer Vasily Tatishchev under the orders of Peter I. Earlier, in the 17th century, rich ore deposits were discovered in
11880-768: Was the great elm that towered above its two siblings at the bottom of Long Melford Green, Long Melford , Suffolk, till the group succumbed to disease in 1978. The three "were survivors of a former clone of at least nine elms, one dating from 1757". The Long Melford elms were painted in 1940 by the watercolourist S. R. Badmin in his 'Long Melford Green on a Frosty Morning', now in the Victoria and Albert Museum . The largest known surviving trees in England are at East Coker , Somerset (30 m high, 95 cm d.b.h. ), Termitts Farm near Hatfield Peverel , Essex (25 m high, 145 d.b.h.), and Melchbourne , Bedfordshire , (147 cm d.b.h.). The name Ulmus minor subsp. minor
11990-896: Was used by R. H. Richens for field elm that was not English elm , Cornish elm , Plot elm or Guernsey elm . Many publications, however, continue to use plain Ulmus minor for undifferentiated field elm; indeed Dr Max Coleman of Royal Botanic Garden Edinburgh argued in his 2002 paper 'British Elms' that there was no clear distinction between species and subspecies. Some authorities, among them Richens and Coleman, include English elm among varieties of field elm, Richens calling English elm U. minor var. vulgaris . Richens sank as undifferentiated U. minor certain local English forms such as U. minor 'Goodyeri' , U. minor 'Hunnybunii' , U. minor 'Sowerbyi' , and U. minor 'Coritana' . Henry 's Ulmus nitens var. italica , 'Mediterranean Elm' (1913), distinguished by its 14 to 18 pairs of leaf-veins,
12100-607: Was widely planted in Edinburgh in the 19th century as a park and avenue tree, and despite losses, it remains abundant there, regenerating through seedlings. It was introduced to New England in the 18th century, to Canada (as U. montana at the Dominion Arboretum , Ottawa ) and Australia in the 19th century. Wych elm wood is prized by craftsmen for its colouring, its striking grain, its 'partridge-breast' or 'catspaw' markings, and when worked, its occasional iridescent greenish sheen or 'bloom'. The bosses on old trees produce
