The rising sap in spring can be used to make refreshing drinks, wines, ales and liqueurs and various parts of the tree have been used in herbal medicine. The leaves of the downy birch are rounder in shape than those of silver birch. Genus Betula can be deciduous trees or shrubs, usually colouring well in autumn and often with striking white, pink, or peeling brown bark; separate male and female … A number of cultivars have been developed but many are no longer in cultivation. 2–20 m (6.5–65 ft.), usu. It tolerates poor soils and harsh frosts and copes well with drought. Flowers when coming into leaf. It has serrate leaves, not doubly serrate like silver birch. Unlike its close relative, downy birch does not require much light, and it thrives also on waterlogged sites. Downy Birch leaves have a grey underside (left) that are slightly hairy but in the main only when the leaf is young. Both silver birch and downy birch have a wide natural dis-tribution area on the Eurasian continent, ranging from the Silviculture of birch ( Betula pendula Roth and Betula pubescens Ehrh.) Habitat: Moist coniferous and mixed forests, spruce swamps, eutrophic fens, ditches, shores, field and road margins. [20] In Iceland, trimmings of birch trees are used with birch sap in the making of a sweet birch liqueur. Downy birch is also a pioneer species, especially in Northern Finland. Planted Downy Birch are more susceptible to Birch dieback, a disease caused by the pathogenic Fungi Marssonia betulae and Anisogramma virgultorum. Betula pubescens is commonly known as downy birch, with other common names including moor birch, white birch, European white birch or hairy birch. [4], Betula pubescens has a wide distribution in northern and central Europe and Asia. [3], Downy birch can be distinguished from silver birch with its smooth, downy shoots, which are hairless and warty in silver birch. Inflorescences dense, pendent catkins formed by numerous, 2–3-flowered cymes. Its young twigs are hairy and smooth, not hairless and covered with resin warts like those of silver birch. Downy birch is a deciduous broad-leaf tree native to the UK and northern Europe and northern Asia. [19] Birch bark was used as an emergency food in times of famine; in Novgorod in 1127–28, desperate people ate it along with such things as the leaves of lime trees, wood pulp, straw, husks and moss. Betula pubescens (syn. The leaf margins also differ, finely serrated in downy birch, coarsely double-toothed in silver birch. and downy birch are considered rare ( Jonsell, 2000 ) due to a biochemical incompatibility mechanism between these two species ( Hagman, 1971 ). Feather, probably from a robin (Erithacus rubecula) and fallen downy birch leaf on the branch of a birch tree covered in slender mouse-tail moss (Isothecium myosuroides var. Downy Birch (B. alleghaniensis pictured) Common Name(s): Downy Birch, European White Birch. Birch leaves are a source of food for various butterflies. The shoots are grey-brown with fine downy. Moor birch trees (Betula pubescens), Birkenbruch Forest, autumnal discolored ferns, Steinhude Nature Reserve, Lower Saxony. Distribution: Northern Europe, Asia, Iceland, and Greenland. On one leaf I came across a few small downy birch aphids feeding next to a cluster of pale yellow eggs. [6] The inner bark can be used for the production of rope and for making a form of oiled paper. This variety is notable as being one of very few trees native to Iceland and Greenland, and is the only tree to form woodland in Iceland. myosuroides) on the trunk of a downy birch tree beside the Burn of Segal. They are also prone to a few pests such as the Bronze Birch Borer and Asian Longhorn beetle. These may eventually overshadow the downy birch and replace it as the dominant tree. [4], Three varieties are recognised, the nominate Betula pubescens var. Flowering time: April–June. This makes it possible for other, more demanding trees to move in. pumila (arctic downy birch or mountain birch, formerly called B. p. subsp. In terms of genetic structure, the trees are quite different, but do, however, occasionally hybridise. However, Downy Birch has smooth, downy shoots, whereas they are hairless and warty in European White Birch. As successive generations live, shed leaves and die, a richer soil underneath the trees builds up. Leaf Properties & Uses: ... Downy Birch also has a more upright growth habit of the branches, compared with Silver birch that does the more stereotypical cascading, ‘pendulous’ branches. (e.g., first appearance of species, flowering, ripening, leaf yellowing, snow fall, and melt). Buds: Narrowly tapering, rather small, brown, sometimes greenish. Damage to the leaf tissue stimulates the tree to produce chemicals that reduce foliage quality, retarding the growth of the larvae and reducing their pupal weights. In Scandinavia and Finland, this is done on a domestic scale, but in the former USSR, particularly Russia, Ukraine, Belarus, Estonia, Latvia and Lithuania, birch sap is harvested commercially and used to manufacture cosmetics, medicines and foodstuffs. It grows to an altitude of 760 m in Scotland. The fruit is a pendulous, cylindrical aggregate 1 to 4 cm (0.4 to 1.6 in) long and 5 to 7 mm (0.2 to 0.3 in) wide which disintegrates at maturity, releasing the individual seeds; these seeds are 2 mm (0.08 in) long with two small wings along the side. The inner bark is edible and it was ground up and used in bread-making in times of famine. Huge collection, amazing choice, 100+ million high quality, affordable RF and RM images. Autumn colour yellow to orange. Leaves: Ovate, short-pointed, serrate (with sawlike margins), often hairy beneath. Betula pubescens is commonly known as downy birch, with other common names including moor birch, white birch, European white birch or hairy birch. Downy birch is the most commonly seen birch in Northern Ireland. Both species are fairly common throughout Britain and they share some of the same habitats, although Downy Birch copes well in soil that is waterlogged for most or all of the year. The bark can also be turned into a high quality charcoal favoured by artists. Elizabeth M. Williamson . Young leaves of Downy Birch are thinly pubescent. The trunks of birches are covered with white or darkish, often papery bark. litwinowii (distributed in the Caucasus and Turkey) and B. p. var. Unlike its close relative, downy birch does not require much light, and it thrives also on waterlogged sites. This is how north-western Europe was recolonised by trees following th… pubescens, B. p. var. myosuroides). All three species can be distinguished cytologically, silver birch and dwarf birch being diploid (with two sets of chromosomes), whereas downy birch is tetraploid (with four sets of chromosomes). Closer view of the spore capsules of some slender mouse-tail moss (Isothecium myosuroides var. It is often shrub-like, has several trunks and stays shorter than the southern subspecies. downy birch: leaf: Indoors, in greenhouse, captivity, culture or experimentally induced (early 4-)5-6(-12) adult feeds on leaf: leaf: leaf is grazed by adult: Cryptocephalus decemmaculatus: 10-spotted Pot Beetle: Coleoptera: Chrysomelidae: Atlas of the Seed and Leaf Beetles of Britain and Ireland, Cox, M.L., 2007 Tough and flexible timber of downy birch is good for making furniture. Nowadays, cardboard boxes are used, but imprinted with the typical bark pattern. Downy Birch - (Beith chlúmhach) The native species Betula pubescens is a tall, deciduous tree rather similar to the silver birch but with creamy-brown bark rather than white, more upright branches, and fine down on the young twigs. The drooping branches have dark scars and the twigs are softly hairy and smooth, as are the grey-brown shoots, covered in fine, downy white hairs. woodlands. Find the perfect downy birch leaf stock photo. In Iceland, dwarf birch and downy birch sometimes hybridise, the resulting plants being triploid (with three sets of chromosomes). Leaf. The flowers are wind-pollinated catkins, produced in early spring before the leaves. Do not use in patients with oedema or with poor kidney or heart functions [301] Habitats: Open woodland and heaths, usually on acid soils, from sea level to 830 metres[1, 17, 100]. Many fungi are associated with the tree and certain pathogenic fungi are the causal agents of birch dieback disease. It has serrate leaves, not doubly serrate like silver birch. Silver Birch, Common Alder, Dwarf Birch, Grey Alder, Hazel, Silver Birch. The silver birch has pointed, triangular leaves. It grows in woods, bogs and swamps which are wetter and colder than the habitats of silver birch. BETULA PUBESCENS – Downy Birch Characteristics Many people find it difficult to distinguish between Betula pendula – Silver Birch and Betula pubescens – Downy Birch, particularly when they are young. Simple leaf that is roughly triangular with rounded corners and a leaf margin that is quite toothed (serrated). Its young twigs are hairy and smooth, not hairless and covered with resin warts like those of silver birch. This can be consumed fresh, concentrated into a syrup similar to the better-known maple syrup, or can be fermented into an ale or wine. At one time the island is thought to have been covered in downy birch woodland, but that cover is reduced to about one percent of the land surface today. Downy Birch (right) have more rounded, ovate leaves with less acutely pointed tips. Its range extends from Newfoundland, Iceland, the British Isles and Spain eastwards across northern and central Europe and Asia as far as the Lake Baikal region in Siberia. Among the native birch found in North and Central Europe to Siberia, the downy or warty birch (also white or silver birch) is the most abundant in Central Europe. However, naturally formed Downy Birch appears to be more resistant to it. Search for more papers by this author. downy birch (Betula pubescens), birch leaf, Germany. Pests: ‘Witches brooms’ are a type of gall caused by . The Downy birch is a small, spindly tree with thin branches and papery bark. Dwarf Birch, – In Wielgolaski, E. Downy birch is a deciduous broadleaf tree native to the UK and northern Europe and northern Asia It is also known as moor birch, white birch, common white birch and European white birch Downy birch is found on damper soils than silver birch, and can even tolerate waterlogged or peaty condition It quickly grows into a tree, up to 30m, with a dominant trunk and overhanging branches. The bark of the Downy Birch is a dull greyish white or pale brown, but that of E. White Birch is striking white, papery, with black fissures. The bark of the downy birch is a dull greyish white, whereas the silver birch has striking white, papery bark with black fissures. [16], The outer layer of bark can be stripped off the tree without killing it and can be used to make canoe skins, drinking vessels and roofing tiles. The bark can be stripped off without killing the tree and the bark and the timber is used for turnery and in the manufacture of plywood, furniture, shelves, coffins, matches, toys and wood flooring. In the fjeld district in the far north mountain birch (ssp. Both can get to 20m (65ft) have silvery white bark and a similar shaped leaf. [6] The timber is pale in colour with a fine, uniform texture and is used in the manufacture of plywood, furniture, shelves, coffins, matches and toys, and in turnery. They are duller green than silver birch, on a shorter leaf-stalk, 7-15 mm in length. Yet, downy birches are characterised by hairy leaves and young shoots, whereas the same parts on silver birch are hairless. Scientific Name: Betula pubescens. [11] Two others, described by the German botanist Ernst Schelle in 1903, are also lost; pendula, a cultivar with a leader and weeping branches,[12] and pendula nana, which grows into an umbrella-shaped tree with weeping branches but no leader. Appearing from April to May, male catkins are long and yellow-brown in colour. [12], The larva of the autumnal moth (Epirrita autumnata) feeds on the foliage of Betula pubescens and other tree species. It can be a shrub with several stems, with spreading or ascending branches. True to its species name, its twigs are covered in short, stiff hairs. [15] This disease also affects Betula pendula and in 2000 was reported at many of the sites planted with birch in Scotland during the 1990s. The shoots are grey-brown with fine downy. [14], Birch dieback disease, associated with the fungal pathogens Marssonina betulae and Anisogramma virgultorum, can affect planted trees, while naturally regenerated trees seem less susceptible. Many of the birch trees that we see in the countryside in Britain and Ireland are not true Silver Birches but hybrids between Betula pendula and the Downy Birch Betula pubescens. The two species can be distinguished by their leaves, with those of downy birch being rounder in shape than silver birch, and having a single row of teeth on the leaf margin, in contrast to the double row of teeth on silver birch leaves. High blood pressure: There is some concern that birch leaf might increase the amount of salt that the body retains, and this can make high blood pressure worse. 8–20 m. Flower: Small, greenish to brownish, lacking perianth. ID check. pubescens and B. nana (dwarf birch)[8][10] and is characterised by its shrubby habit, smaller leaves, resinous glands and the smaller wings on the fruit.

Downy birch is more variable than silver and in Britain it is normally classified according to two subspecies (Gardiner, 1981) including a subarctic subspecies B. pubescens ssp.‘tortuosa’ (a.k.a. Narrowly conical habit. [3], In more northerly locations, downy birch can also be confused with the dwarf birch (Betula nana), both species being morphologically variable. The leaves of silver birch are more noticeably serrated - even the teeth may have teeth! Inês da Costa Rocha. This bark is also rich in tannin and has been used as a brown dye and as a preservative. They include "Armenian gold", "Arnold Brembo" (scented foliage), crenata nana (shrubby and dwarf), incisa (lobed foliage), integrifolia (unlobed foliage), murigthii (shrubby with doubly serrate leaves), ponitica (hairless), undulata (leaf margins waxy), urticifolia (nettle-leaved), variegata (variegated) and "Yellow wings". The leaves are ovate-acute, 2 to 5 cm (0.8 to 2.0 in) long and 1.5 to 4.5 cm (0.6 to 1.8 in) broad, with a finely serrated margin. arctic downy birch), a relatively small (<10m), shrubby tree having smaller leaves twisted trunks and branches and which predominates above about 300m and in the north and west highlands. Downy birch, also known as white birch, is a very variable tree. [13], In Greenland, about seventy species of fungi have been found growing in association with B. pubescens, as parasites or saprobes on living or dead wood. All rights reserved. [9] The latter has arisen from the hybridization of var. Male and female flowers in separate inflorescences. (ed. Always green at emergence. The genus Betula comprises some 40 species, both trees, shrubs, and dwarf shrubs. [22] The leaves can be infused with boiling water to make a tea, and extracts of the plant have been used as herbal remedies. tortuosa). a fungus (Taphrina betulina). White Birch, Downy birch: Family: Betulaceae: USDA hardiness: Coming soon: Known Hazards : The aromatic and aliphatic hydrocarbons in birch tar are irritating to the skin. [2] Growing form and height: Tree with a single trunk or shrub with several main stems. Downy birch is monoecious, meaning both male and female flowers (catkins) are found on the same tree. In outbreak years, large areas of birch forest can be defoliated by this insect. The tree is a pioneer species, readily colonising cleared land, but later being replaced by taller, more long-lived species. Some of the most common fungi include Ceriporia reticulata, Chondrostereum purpureum, Exidia repanda, Hyphoderma spp, Inonotus obliquus, Inonotus radiatus, Mycena galericulata, Mycena rubromarginata, Panellus ringens, Peniophora incarnata, Phellinus lundellii, Radulomyces confluens, Stereum rugosum, Trechispora spp., Tubulicrinis spp. They flower when coming into leaf in the spring. Specimens of the subarctic populations are usually small and very contorted, and are often distinguished as arctic downy birch or mountain birch, B. p. var. The range extends southwards to about 40°N, its southernmost limit being Turkey, the Caucasus and the Altai Mountains. [2][3], B. pubescens is closely related to, and often confused with, the silver birch (B. pendula). My immediate intuition was that these must be eggs of the two-spot ladybird, so I photographed them and then later compared the photo with images on the Internet of ladybird eggs – it looked like I was correct. UCL School of Pharmacy, UK. Tree Size: 33-65 ft (10-20 m) tall, 1-2 ft (.3-.6 m) trunk diameter. © Copyright: Images: Jouko Lehmuskallio. and hybrids Sarah E. Edwards. It is found on heathland, moorland and mountainsides, as well as on damp soils. The larva of the autumnal moth (Epirrita autumnata) feeds on the foliage and in some years, large areas of birch forest can be defoliated by this insect. The two have differences in habitat requirements, with downy birch more common on wet, poorly drained sites, such as clays and peat bogs, and silver birch found mainly on dry, sandy soils. No need to register, buy now! Birch Rust caused by Melampsoridium betulinum on leaf of downy birch or Betula pubescens - Buy this stock photo and explore similar images at Adobe Stock Sales: 888-649-2990 Sell [2], Both B. pubescens and B. pendula can be tapped in spring to obtain a sugary fluid. [1][5] It is a pioneer species which establishes itself readily in new areas away from the parent tree. pumila. [17], The Sami people of Scandinavia used the bark of both B. pubescens and B. pendula as an ingredient in bread-making; the reddish phloem, just below the outer bark, was dried, ground up and blended with wheat flour to make a traditional loaf. [7][8] (not to be confused with B. nana). The observations are collected either on paper and are subsequently submit-ted manually to an open-source online database or submitted directly via a newly developed mobile app. The twigs and young branches are very flexible and make good whisks and brooms. Downy birch, also known as white birch, is a very variable tree. ), 10.2305/IUCN.UK.2014-3.RLTS.T194521A2344298.en, European Forest Genetic Resources Programme, https://en.wikipedia.org/w/index.php?title=Betula_pubescens&oldid=992415464, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 December 2020, at 04:05. Leaves can be used as tea and in herbal medicines, and sap as a stimulating drink in spring. Many North American texts treat the two species as conspecific (and cause confusion by combining the downy birch's alternative vernacular name, white birch, with the scientific name B. pendula of the other species), but they are regarded as distinct species throughout Europe. Downy birch is native to Europe but has naturalized in Connecticut, Massachusetts, Maine, and Vermont. Average Dried Weight: 39 lbs/ft 3 (625 kg/m 3) Specific Gravity (Basic, 12% MC):.48, .62. It is closely related to, and often confused with, the silver birch (B. pendula), but grows in wetter places with heavier soils and poorer drainage; smaller trees can also be confused with the dwarf birch (B. nana). Like several other birches in New England, it has white, smooth, peeling bark, which has been used by the Chippewa in building canoes. Betula alba), commonly known as downy birch and also as moor birch, white birch, European white birch or hairy birch, is a species of deciduous tree, native and abundant throughout northern Europe and northern Asia, growing farther north than any other broadleaf tree. In spring, the male catkins (or 'lamb's tails') turn yellow and shed their pollen, which is carried by the wind to the short, green, female catkins that appear on the same tree. [23], {{cite iucn}}: error: |doi= / |page= mismatch (, Väre, H. 2001: Mountain birch taxonomy and floristics of mountain birch The edge of the leaf is doubly toothed (unlike the downy birch which is singly toothed). The small flowers are unisexual, the inflorescence a catkin-like, dense compound cyme. Subspecies: Downy Birch or White Birch (ssp. The leaf base of silver birch is usually a right angle to the stalk, while for downy birches, it is rounded. and Tyromyces chioneus. Three varieties are recognised and it hybridises with the silver and dwarf birches. The leavesare ovate-acute, 2 to 5 cm (0.8 to 2.0 in) long and 1.5 to 4.5 cm (0.6 t… Areas of poor soil are quickly colonised by this tree. Downy beech is a deciduous tree with a single trunk up to 25 m in height. It is a deciduous tree growing to 10 to 20 m (33 to 66 ft) tall (rarely to 27 m), with a slender crown and a trunk up to 70 cm (28 in) (exceptionally 1 m) in diameter, with smooth but dull grey-white bark finely marked with dark horizontal lenticels. This allows other woodland trees to become established and the birch, a short-lived tree, eventually gets crowded out as its seedlings are intolerant of shady conditions. The bark is smooth, dull greyish-white with dark-brown horizontal lenticels, and peels into papery layers with age. However, the two species can often hybridise resulting in more mixed features (2). [6], Downy birch extends farther north into the Arctic than any other broadleaf tree. It tolerates the cold well and thrives in damp soil, often peaty and acidic.
