[5] A large number of synonyms have accumulated over the last three centuries; their currently accepted names can be found in the list List of elm Synonyms and Accepted Names. Vegetative reproduction is also used to produce genetically identical elms (clones). The elm occurs frequently in English literature, one of the best known instances being in Shakespeare's A Midsummer Night's Dream, where Titania, Queen of the Fairies, addresses her beloved Nick Bottom using an elm-simile. The larvae feed only on elm. Cherry Bark Elm Tree (Ulmus villosa Brandis ex Gamble) Ulmus villosaalso referred to as Cherry Bark elm is a long lived deciduous tree native to the North West and western Himalaya. These beetles burrow into the bark of elm trees, which makes them difficult to locate once they’ve settled on a tree. Its mid green leaves are elliptic with serrated margins, and turns yellow before they fall in … The mutant-elm cultivars are usually grafted, the ‘weeping' elms 'Camperdown' and 'Horizontalis' at 2–3 m (6 ft 7 in–9 ft 10 in), the dwarf cultivars 'Nana' and 'Jacqueline Hillier' at ground level. [32], However, some of these cultivars, notably those with the Siberian elm (Ulmus pumila) in their ancestry, lack the forms for which the iconic American Elm and English Elm were prized. Since the Siberian Elm is drought-tolerant, in dry countries new varieties of elm are often root-grafted on this species. The trees are particularly noteworthy along the Mall and Literary Walk, where four lines of American elms stretch over the walkway forming a cathedral-like covering. [44], The density of elm wood varies between species, but averages around 560 kg per cubic metre. The genus first appeared in the Miocene geological period about 20 million years ago, originating in what is now central Asia. An Elm Tree and Three Sisters by Norma Sommerdorf is a children's book about three young sisters that plant a small elm tree in their backyard. Slippery elm (Ulmus rubra Muhl.) Click on images of American Elm to enlarge. In northern Europe elms were, moreover, among the few trees tolerant of saline deposits from sea spray, which can cause "salt-burning" and die-back. Their range extends as far south as … Elm Tree Bark, Photo of American Elm Trunk, Close up Identification Photo of Elm Wood, Elm Trees Bark. ', Heybroek, H. M., 'Resistant Elms for Europe' (1982) in, elmcare.com/about_elms/history/liberty_elm_boston.htm, Νίκος Μπελαβίλας, ΜΥΘΟΙ ΚΑΙ ΠΡΑΓΜΑΤΙΚΟΤΗΤΕΣ ΓΙΑ ΤΟ ΜΗΤΡΟΠΟΛΙΤΙΚΟ Elm has been listed as one of the 38 substances that are used to prepare Bach flower remedies,[53] a kind of alternative medicine. In their natural setting native species, such as wych elm and European White Elm in central and northern Europe and field elm in southern Europe, set viable seed in ‘favourable' seasons. The National Elm Trial in North America, begun in 2005, is a nationwide trial to assess strengths and weaknesses of the 19 leading cultivars raised in the US over a ten-year period; European cultivars have been excluded. As a result, the population of American elms planted on the Mall and its surrounding areas has remained intact for more than 80 years.[42]. The devastation caused by the Second World War, and the demise in 1944 of the huge Späth nursery in Berlin, only accelerated the process. DNR RESPONSE TO COVID-19: For details on adjustments to DNR services, visit this webpage.For information on the state’s … During the Middle Ages elm was also used to make longbows if yew was unavailable. [46] Ovid in his Amores characterizes the elm as "loving the vine": ulmus amat vitem, vitis non deserit ulmum (:the elm loves the vine, the vine does not desert the elm),[47] and the ancients spoke of the "marriage" between elm and vine. [41], Several rows of American elm trees that the National Park Service (NPS) first planted during the 1930s line much of the 1.9 miles (3.0 km) length of the National Mall in Washington, D.C. DED first appeared on the trees during the 1950s and reached a peak in the 1970s. The tree disease was first found in America in 1930 and was thought to have entered the country via elm logs imported from Europe for the manufacture of veneer in the plywood industry. Some of the latter, however, were by today's standards inadequately described or illustrated before the pandemic, and it is possible that a number survive, or have regenerated, unrecognised. Genotype × environment interaction and growth stability of several elm clones resistant to Dutch elm disease. thank you, terry whitford. [18][19], In 1993, Mariam B. Sticklen and James L. Sherald reported the results of experiments funded by the United States National Park Service and conducted at Michigan State University in East Lansing that were designed to apply genetic engineering techniques to the development of DED-resistant strains of American elm trees. A part of New York City's urban ecology, the elms improve air and water quality, reduce erosion and flooding, and decrease air temperatures during warm days. The genus is hermaphroditic, having apetalous perfect flowers which are wind-pollinated. The elm's wood bends well and distorts easily making it quite pliant. The NPS combated the disease's local insect vector, the smaller European elm bark beetle (Scolytus multistriatus), by trapping and by spraying with insecticides. Other articles where American elm is discussed: elm: Major species: The American elm (Ulmus americana), of eastern North America, may grow 24 to 30 metres (about 80 to 100 feet) tall. Owing to its geographical isolation and effective quarantine enforcement, Australia, has so far remained unaffected by Dutch Elm Disease, as have the provinces of Alberta and British Columbia in western Canada. Some individual elms reached great size and age. Should you find or know where to find one of these rare American Elms, please record the location of the tree, its DBH at 4.5 feet above the ground and submit this information to the survivor elm website. Most serious of the elm pests is the elm leaf beetle Xanthogaleruca luteola, which can decimate foliage, although rarely with fatal results. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Breeding and scientific advances in the fight against Dutch elm disease: Will they allow the use of elms in forest restoration? Elms are a recurring element in the landscapes and studies of, for example, John Constable, Ferdinand Georg Waldmüller, Frederick Childe Hassam, Karel Klinkenberg,[57] and George Inness. Santamour, J., Frank, S. & Bentz, S. (1995). In the first Idyll of Theocritus (3rd century BC), for example, the goat-herd invites the shepherd to sit "here beneath the elm" ("δεῦρ' ὑπὸ τὰν πτελέαν") and sing. [8] The samarae are very light, those of British elms numbering around 50,000 to the pound (454 g). Slow-germinating American Elm will remain dormant until the second season. Brasier, C. M. (1996). The trunk of the American elm tree is gray and furrowed, whereas that of the Chinese elm tree (also known as Lace Bark elm) has a scale-like bark that is more brown in color when young, and turns to an appealing combination of crimson, green and orange when mature. Dutch elm disease history and diagnosis. [60] Although intensive feeding by elm bark beetles can kill weakened trees, their main impact is as vectors of DED. In south-eastern Australia and New Zealand, large numbers of English and Dutch elms, as well as other species and cultivars, were planted as ornamentals following their introduction in the 19th century, while in northern Japan Japanese Elm (Ulmus davidiana var. Slippery elm leaves are scabrous even on mature trees, lateral leaf veins typically fork near the leaf margin, the bark is brown to reddish, lateral buds are reddish, blunt, scales pubescent, twigs are roughened by persistent bases of hairs, and the samara is suborbicular and margin not ciliate. Martín-Benito D., Concepción García-Vallejo M., Pajares J. These efforts have largely been successful in saving the majority of the trees, although several are still lost each year. [80] By contrast, a famous Parisian elm associated with the Ancien Régime, L'Orme de Saint-Gervais in the Place St-Gervais, was felled by the revolutionaries; church authorities planted a new elm in its place in 1846, and an early 20th-century elm stands on the site today. The tree likes sun at the location and the soil should be alluvial soils. I can send you leaf and tree photos. There are now disease resistant varieties being introduced to the market, but we recommend exercising caution when planting these and not to over-plant. The bark is ashy gray with flat-topped ridges separated by diamond-shaped fissures. Egg of Satyrium w-album near flower-bud of an elm. Elms are deciduous and semi-deciduous trees comprising the flowering plant genus Ulmus in the plant family Ulmaceae. Moreover, several exported to northwestern Europe have proven unsuited to the maritime climate conditions there, notably because of their intolerance of anoxic conditions resulting from ponding on poorly drained soils in winter. Maunder, M. (1988). novo-ulmi, caused similar devastation in Eastern Europe and Central Asia. These proud, attractive trees were a favorite in cities and suburbs across the U.S. and were found throughout forests in their native range. A., García, S., Díez, J. J., Martín, D. & García-Vallejo, M. C. 2004. [1] These trees flourished and spread over most of the Northern Hemisphere, inhabiting the temperate and tropical-montane regions of North America and Eurasia, presently ranging southward in the Middle East to Lebanon, and Israel,[2] and across the Equator in the Far East into Indonesia.[3]. I have 3 pictures of what might be elm leaves from a tree next to my property in Oscoda Township, Michigan, 48750. In a chance event linking elms and revolution, on the morning of his execution (30 January 1649), walking to the scaffold at the Palace of Whitehall, King Charles I turned to his guards and pointed out, with evident emotion, an elm near the entrance to Spring Gardens that had been planted by his brother in happier days. [10] The hypothesis that O. novo-ulmi arose from a hybrid of the original O. ulmi and another strain endemic to the Himalaya, Ophiostoma himal-ulmi is now discredited. Brasier, C. M. & Mehotra, M. D. (1995). Elm-bark beetle Scolytus multistriatus (size: 2–3 mm), a vector for Dutch Elm Disease. Decimated by Dutch elm disease in the 1950s, the once-widespread American elm whithered and died throughout its range across eastern North America. Another unwelcome immigrant to North America is the Japanese beetle Popillia japonica. In England after the Glorious Revolution of 1688, the final victory of parliamentarians over monarchists, and the arrival from Holland, with William III and Mary II, of the 'Dutch Elm' hybrid, planting of this cultivar became a fashion among enthusiasts of the new political order.[76][77]. These proud, attractive trees were a favorite in cities and suburbs across the U.S. and were found throughout forests in their native range. In Germanic and Scandinavian mythology the first woman, Embla, was fashioned from an elm,[71] The influence of Dutch elm disease on bird population trends. It is a deciduous tree, creating a long spreading canopy, and self-pollinating flowers. [69] It has been noted[70] that two elm-motifs have arisen from classical literature: (1) the 'Paradisal Elm' motif, arising from pastoral idylls and the elm-and-vine theme, and (2) the 'Elm and Death' motif, perhaps arising from Homer's commemorative elms and Virgil's Stygian Elm. The Arbor Day Foundation points out that an American elm tree in New York is estimated to be more than 650 years old. Millions of these trees were lost to Dutch Elm Disease. Elm was also used as piers in the construction of the original London Bridge. Dutch elm disease (DED) devastated elms throughout Europe and much of North America in the second half of the 20th century. On young trees, trunk bark is gray and slightly rough overall, but it often has irregular longitudinal stripes that are colored black and white. The disease affects both wild-growing and cultivated trees. Decimated by Dutch elm disease in the 1950s, the once-widespread American elm whithered and died throughout its range across eastern North America. The first, less aggressive strain of the disease fungus, Ophiostoma ulmi, arrived in Europe from Asia in 1910, and was accidentally introduced to North America in 1928. The outbreak of the new, three times more virulent, strain of Dutch elm disease Ophiostoma novo-ulmi in the late 1960s brought the tree to its nadir. DED is caused by a micro-fungus transmitted by two species of Scolytus elm-bark beetle which act as vectors. Botanists who study elms and argue over elm identification and classification are called pteleologists, from the Greek πτελέα (:elm).[6]. The transplanting of root-suckers remains the easiest and commonest propagation-method for European field elm and its hybrids. Leaves are typically 4 to 6 inches long with feather-like veins, double serrate margins and an oblique base (Figure 13). The American Elm, is a disease resistant elm tree that can grow to heights of 100 feet or more, with a trunk averaging around 4 feet in diameter. Court filing could end Great Lakes fishing as we know it →. [68] When the Sibyl of Cumae leads Aeneas down to the Underworld, one of the sights is the Stygian Elm: Virgil refers to a Roman superstition (vulgo) that elms were trees of ill-omen because their fruit seemed to be of no value. The fruit is a round wind-dispersed samara flushed with chlorophyll, facilitating photosynthesis before the leaves emerge. In response, disease-resistant cultivars have been developed, capable of restoring the elm to forestry and landscaping. Elms are components of many kinds of natural forests. Since circa 1990 the elm has enjoyed a renaissance through the successful development in North America and Europe of cultivars highly resistant to DED. Trees in areas unaffected by Dutch elm disease (DED) can live for several hundred years. [43] Hesiod says that ploughs in Ancient Greece were also made partly of elm. ← Spotted Knapweed Removal at Kitchel-Lindquist-Hartger Dunes Preserve! American elm trees (Ulmus americana) are the most susceptible of all to Dutch elm disease. In the Netherlands, sales of elm cultivars slumped from over 56,000 in 1989 to just 6,800 in 2004,[39] whilst in the UK, only four of the new American and European releases were commercially available in 2008. American elm lining a suburban street. [86], Planting a Liberty Tree (un arbre de la liberté) during the French Revolution. Dutch Elm Disease is a fungus which is spread by the elm bark beetle It has dark gray, ridged bark and elliptical leaves. "Elms" redirects here. [14] Infection and death of the phloem effectively girdles the tree and stops the flow of water and nutrients. In Greek mythology the nymph Ptelea (Πτελέα, Elm) was one of the eight Hamadryads, nymphs of the forest and daughters of Oxylos and Hamadryas. A.K.A. The native range of the American elm. The bodies of Japanese Taiko drums are often cut from the wood of old elm trees, as the wood's resistance to splitting is highly desired for nailing the skins to them, and a set of three or more is often cut from the same tree. American elm is characterized by grayish, brown, deep furrowed bark (Figure 12). 'Cockscomb' leaf-galls (aphid Colopha compressa), Poland. Elms outside their natural range, such as Ulmus procera in England, and elms unable to pollinate because pollen-sources are genetically identical, are sterile and are propagated by vegetative reproduction. Photo provided by Michigan DNR. Research in Spain has suggested that it may be the presence of a triterpene, alnulin, which makes the tree bark unattractive to the beetle species that spread the disease. [89] Since elms may hybridize within and between species, seed-propagation entails a hybridisation risk. Woodland trees in North America are not quite as susceptible to the disease because they usually lack the root-grafting of the urban elms and are somewhat more isolated from each other. [82] In the French Republican Calendar, in use from 1792 to 1806, the 12th day of the month Ventôse (= 2 March) was officially named "jour de l'Orme", Day of the Elm. American elm trees are also known as water elms, soft elms, white elms, or Florida elms. [84][85] In an ironic development, feral elms have spread and invaded the grounds of the abandoned Greek royal summer palace at Tatoi in Attica. A bottom heat of 18 degrees[92] and humid conditions are maintained for hard- and softwood cuttings. The beetle was accidentally introduced to North America from Europe. The disease is caused by a fungus that infects the trees and whose spores are spread by bark beetles. Dutch hybridizations invariably included the Himalayan elm (Ulmus wallichiana) as a source of anti-fungal genes and have proven more tolerant of wet ground; they should also ultimately reach a greater size. 'Pimple' leaf-galls on a field elm (mite Eriophyes ulmi), Spain. [83] After the Greek Revolution of 1821–32, a thousand young elms were brought to Athens from Missolonghi, "Sacred City of the Struggle" against the Turks and scene of Lord Byron's death, and planted in 1839–40 in the National Garden. Collin, E. (2001). [50], As fossil fuel resources diminish, increasing attention is being paid to trees as sources of energy. Eight species are endemic to North America and three to Europe, but the greatest diversity is in Asia with approximately two dozen species.[3]. [citation needed]. [81] Premier Lionel Jospin, obliged by tradition to plant a tree in the garden of the Hôtel Matignon, the official residence and workplace of Prime Ministers of France, insisted on planting an elm, so-called 'tree of the Left', choosing the new disease-resistant hybrid 'Clone 762' (Ulmus 'Wanoux' = Vada). The American Elm is botanically called Ulmus americana. No need to register, buy now! The seeds are particularly nutritious, containing 45% crude protein, and less than 7% fibre by dry mass.[52]. American elm is a vase-shaped, medium to large, deciduous tree that typically grows to 60-80’ tall with a broad-rounded crown. The elm tree can grow to great height, often with a forked trunk creating a vase profile. The American elm is an extremely hardy tree that can withstand winter temperatures as low as −42 °C (−44 °F). Pages 20-28 in: Ware, G. (1995). However, in recent decades, most mature elms of European or North American origin have died from Dutch elm disease, caused by a microfungus dispersed by bark beetles. It appeared in the United States sometime in the 1940s, and was originally believed to be a mutation of O. ulmi. Screening European Elms for Resistance to Ophiostoma novo-ulmi. Biggerstaffe, C., Iles, J. K., & Gleason, M. L. (1999). It is caused by phytoplasmas which infect the phloem (inner bark) of the tree. There are two examples of pteleogenesis (:birth from elms) in world myths. Bacterial infection Erwinia carotovora of elm sap, which causes 'slime flux' ('wetwood') and staining of the trunk (here on a Camperdown Elm). [89] Seeds from autumn-flowering elms ripen in the Fall and germinate in the spring. Enthusiasm for the newer clones often remains low owing to the poor performance of earlier, supposedly disease-resistant Dutch trees released in the 1960s and 1970s. In nature, it can be found in swamps, bottomland forests, moist slopes, and in areas with especially nutrient-rich soils. For the racing series, see, Genus of flowering, deciduous tree in the family Ulmaceae, Development of trees resistant to Dutch elm disease, Fu, L., Xin, Y. The name Ulmus is the Latin name for these trees, while the English "elm" and many other European names are either cognate with or derived from it.[7]. In Italy, the Istituto per la Protezione delle Piante is (2012) in the process of releasing to commerce very fast-growing elm cultivars, able to increase in height by more than 2 m (6 ft) per annum. & Whittemore, A. The American elm is highly susceptible to DED and elm yellows. [11], There is no sign of the current pandemic waning, and no evidence of a susceptibility of the fungus to a disease of its own caused by d-factors: naturally occurring virus-like agents that severely debilitated the original O. ulmi and reduced its sporulation.[12]. In: 'Salt-tolerant landscape plants', countyofdane.com/myfairlakes/A3877.pdf, dutchtrig.com/the_netherlands/the_hague.html. [74], The cutting of the elm was a diplomatic altercation between the Kings of France and England in 1188, during which an elm tree near Gisors in Normandy was felled. New horizons in Dutch elm disease control. How to Grow Elm Trees: Elm trees grow best in rich, well-drained soil and full sun. Elm wood is valued for its interlocking grain, and consequent resistance to splitting, with significant uses in wagon wheel hubs, chair seats and coffins. [78] L'Orme de La Madeleine (:the Elm of La Madeleine), Faycelles, Département de Lot, planted around 1790 and surviving to this day, was a case in point. Due to the rarity of the sightings in the Upper Peninsula and the northern Lower Peninsula, anyone with knowledge about the location of a healthy American elm in these regions is particularly encouraged to share information. [78][79] Elm-planting by American Presidents later became something of a tradition. [66], Elms occur often in pastoral poetry, where they symbolise the idyllic life, their shade being mentioned as a place of special coolness and peace. However this resistance to decay in water does not extend to ground contact. On behalf of Midwestern forest researchers, the DNR is now calling on the public to share the locations of surviving American elm trees anywhere in Michigan. Much work has also been done into the selection of disease-resistant Asiatic species and cultivars. It is caused by phytoplasmaswhich infect the phloem (inner bark) of the tree. Heybroek, H. M., Goudzwaard, L, Kaljee, H. (2009). They were particularly popular as a street tree in avenue plantings in towns and cities, creating high-tunnelled effects. Flowers of the hybrid elm cultivar 'Columella', U. americana, Dufferin St., Toronto, c. 1914. According to the Fact Sheet on American Elm - USDA Forest Service ", Once a very popular and long-lived (300+ years) shade and street tree, American Elm suffered a dramatic decline with the introduction of Dutch elm disease, a fungus spread by a bark beetle. Smalley, E. B. Elm-leaf damage caused by Xanthogaleruca luteola, Germany. Their quick growth and variety of foliage and forms,[35] their tolerance of air-pollution and the comparatively rapid decomposition of their leaf-litter in the fall were further advantages. [8] Consequently, the total number of named cultivars, ancient and modern, now exceeds 300, although many of the older clones, possibly over 120, have been lost to cultivation. The disease's infestation of American trees has destroyed more than half of the elm trees in the northern United Sates. Find the perfect elm tree bark stock photo. [87][88], Elm propagation methods vary according to elm type and location, and the plantsman's needs. A., López D. 2005. All states have reported the disease, except those in the … Ulmus americana, American Elm. americana. American Elm is a deciduous tree that may grow 80 to 100 feet tall. The oldest of these elms were planted during the 1860s by Frederick Law Olmsted, making them among the oldest stands of American elms in the world. Its large, dark green foliage forms a dense canopy turning yellow in fall. [33], A number of highly resistant Ulmus cultivars has been released since 2000 by the Institute of Plant Protection in Florence, most commonly featuring crosses of the Dutch cultivar 'Plantijn' with the Siberian Elm to produce resistant trees better adapted to the Mediterranean climate. However, the disease had a much greater and long-lasting impact in North America, owing to the greater susceptibility of the American elm, Ulmus americana, which masked the emergence of the second, far more virulent strain of the disease Ophiostoma novo-ulmi. Jean-Baptiste Lesueur, 1790, Balcony with elm symbol, overlooking the 'Crossroads of the Elm', Place Saint-Gervais, Paris[81], President George W. Bush and Laura Bush planting a disease-resistant 'Jefferson' Elm before the White House, 2006, Elm suckers spreading before the abandoned summer royal palace in Tatoi, Greece, Μarch 2008, The name of what is now the London neighborhood of Seven Sisters is derived from seven elms which stood there at the time when it was a rural area, planted a circle with a walnut tree at their centre, and traceable on maps back to 1619. Many trees were killed by Dutch elm disease, an introduced fungal disease spread by bark beetles, but the population seems to have recovered and American Elm is … The Chinese or Lacebark elm is also more resistant to the disease. Native species may be propagated by seed. 'Pouch' leaf-galls on a wych elm (aphid Tetraneura ulmi), Germany. In the American Revolution 'The Liberty Tree' was an American white elm in Boston, Massachusetts, in front of which, from 1765, the first resistance meetings were held against British attempts to tax the American colonists without democratic representation. American Elm should be grown in full sun on well-drained, rich soil but it adapts to a wide variety of soils. [20] In 2007, AE Newhouse and F Schrodt of the State University of New York College of Environmental Science and Forestry in Syracuse reported that young transgenic American elm trees had shown reduced DED symptoms and normal mycorrhizal colonization. Many artists have admired elms for the ease and grace of their branching and foliage, and have painted them with sensitivity. Dutch elm disease was first discovered in the United States in Ohio in 1930. A second subspecies, O. novo-ulmi subsp. Lopped at three metres, the elms' quick growth, twiggy lateral branches, light shade and root-suckering made them ideal trees for this purpose. Unwelcome immigrant to North America Gil, L.
