Tree Ilm Elm, Karagach in the spring.Karagachfetus The European white elm (Ulmus laevis) is a fast-growing, medium-sized, deciduous tree mostly distributed across Central and Eastern Europe. The European White Elm cultivar Ulmus laevis 'Pendula' is a little-known cultivar of disputed taxonomy. Lowland. [25], The species has a slight to moderate susceptibility to elm yellows. Ulmus minor P-VV1 genotype seeds (the code refers to the Spanish Elm Breeding Program) were collected at Puerta de Hierro nursery (Madrid, 40°27’N, 3°45’W) conservation plot, and U. laevis M-VD.R29 genotype seeds (referring to the Spanish Elm Breeding Program) at Valdelatas forest (Madrid, 40°32’N, 3°40’W). [13], U. laevis 'Helena' as street trees, Eibergen, Netherlands, U. laevis, Roanoke Park, Capitol Hill, Seattle, US (planted 1910), Trimmed U. laevis, Sachsenplatz, Dresden (2019), Windblown laevis on chalk, Salisbury Plain, UK, U. laevis is probably not native to the United Kingdom despite its random occurrence in the countryside, although the date and circumstances of its introduction have not survived. Synonyms: U. campestris L., in part, nom. riparian forest is composed mainly of elms (Ulmus laevis Pall.)

[37], It is possible the tree's distribution was associated with Capability Brown (1716–1783), known to have favoured U. laevis, which he listed among his preferred "native" (sic) trees. pedunculata. vulgaris) 2) Dutch (Ulmus X hollandica) 3) Dutch (Ulmus X hollandica ‘Hollandica) 4) Smoothleaf (Ulmus minor) SEEDS If small & edges ciliated 1) American (Ulmus americana) 2) European white (Ulmus laevis) [21] Ergo: the tree's decline in western Europe is chiefly owing to woodland clearance in river valleys, and river management systems eliminating flooding, not disease. Linear regression identified seed removal by rodents to be frequency‐independent both over the woodland as a whole and within each of six micro‐habitats. long, downy only at the slightly notched apex, the seed situated in the middle. Ulmus laevis is similar in stature to the wych elm, if rather less symmetric, with a looser, untidy, branch structure and less neatly rounded crown. The bark is smooth at first, then in early maturity breaks into thin grey scales, which separate with age into a network of grey-brown scales and reddish-brown underbark, and finally is deeply fissured in old age like other elms. Seeds riping on branch of European white elm or Ulmus laevis, close-up, selective focus, shallow DOF. The seeds, which ripen not later than Midsummer, are round nutlets surrounded by a feathery-edged papery wing about 1 cm across. [16], Typical epicormic shoots and dense branching. [42] James Main mentions the tree as 'a native of Hungary' and in 1838 only to be met in 'ornamental plantations',[44] but by 1846 was 'becoming available in (UK) nurseries'. [9] The leaves are deciduous, alternate, simple ovate with a markedly asymmetric base, < 10 cm long and < 7 cm broad, comparatively thin, often almost papery in texture and very translucent, smooth above with a downy underside. ULMUS ’Rebella’ is a hybrid of ULMUS parvifolia x ULMUS americana bred by Prof. Smalley and Prof. Guries, Madison University Wisconsin / USA.

[17] Moreover, the tree is not favoured by the vector bark beetles, which colonize it only when there are no other elm alternatives available,[18] an uncommon situation in western Europe. 4. However, owing to its rapid growth, tolerance of soil compaction, air pollution and de-icing salts, the tree has long been used for amenity planting in towns and along roadsides.[7].

Two of the three specimens supplied by the Späth nursery, Berlin, to the Royal Botanic Garden Edinburgh in 1902 as U. effusa may survive in Edinburgh, as it was the practice of the garden to distribute trees about the city;[50] the third specimen was in the garden itself. Wych elm Ulmus glabra twigs with leaves and … Vol 1 - 4 and Supplement. The leaf margin is double serrated. The occurrence of phytoplasmas associated with elm yellows (EY) was investigated in the reproductive structures (flowers, unripe and ripe fruits) of two EY-infected trees of the hybrid elm clone Lobel and two healthy trees, an Ulmus laevis and an U. japonica [U. davidiana]. Harris, E. (2017). Research in Spain has indicated that it is the presence of an antifeedant triterpene, alnulin, at a concentration of 200 μg/g {dried bark} which renders the tree unattractive to the beetles. The recommendations provided in this module should be regarded as a commonly agreed basis to be complemented and … This species, which may be resistant to Dutch Elm … [4] NB: The epithet 'white' elm commonly used by British foresters alluded to the timber of the wych elm.

Ulmus laevis is a deciduous tree with a large, spreading, open crown; it can grow 30 metres or more tall, with a bole up to 180cm in diameter[11. Jerinić-Prodanović, D. (2006). [28], U. laevis is comparatively weak-wooded, much more so than field elm Ulmus minor, and thus an inappropriate choice for exposed locations. Significantly, the leaf veins do not divide from the central vein to the leaf margin. FAMILY: ULMACEAE. Five U. laevis populations … We studied Ulmus laevis Pallas reproductive biology in a human transformed population with lack of recruitment, during three consecutive years, in order to evaluate … Bole of ancient tree, showing buttressing and epicormic brush. parvifolia.

A tree at Syon Park identified by Elwes & Henry as U. laevis was later considered by Bean as more closely resembling U. americana by dint of its symmetrical branch arching. In trials in southern England by Butterfly Conservation, young trees of <5 m height were badly damaged by wind gusts of 40 knots (75 km/h) in midsummer storms. The seed is located in the middle. The species is threatened by habitat destruction and disturbance in some countries, notably Spain. Ulmus laevis - Russian, fluttering, or European white elm.

Cut off the seed pod that grows on the Ulmus parvifolia tree during the fall when the pod is still green but fully grown. Height rarely exceeds 100’. Surface root structure exposed by bank erosion, Like other European elms, natural populations of the European white elm have little innate resistance to Dutch elm disease, although research by Irstea has isolated clones able to survive inoculation with the causal fungus, initially losing < 70% of their foliage, but regenerating strongly the following year. Plants, 233. Effect of trace elements on the growth of seedlings of Pinus sylvestris, Ulmus laevis and Lonicera tatarica and the accumulation of carbohydrates. (2012): Seznam cévnatých rostlin květeny České republiky, Preslia 84: 647–811 [jako Ulmus laevis Pall.] There are about 30 to 40 species of Ulmus (elm); the ambiguity in number results from difficulty in delineating species, owing to the ease of hybridization between them and the development of local seed-sterile vegetatively propagated microspecies in some areas, mainly in the field elm (Ulmus minor) group. Seed dispersal Recruitment abstract From a life-cycle perspective seed dispersal is a key factor for population dynamics. Identified as those of the European white elm, Ulmus laevis, hitherto unknown in Ireland, the seeds were grown by Coillte into 15,000 saplings.
