5th December 2012. Last night at the Annual meeting TWIG was officially dissolved, read about in 'News hoots' All funds to be donated to the Green Light Trust.

 
   
   

We hope to list many native British trees on this page, with photos and other information regarding their uses and even the myths relating to them!

Some trees not native to the UK will be listed.  Naturalised trees, those that have been introduced here and are not only growing in our environment, but successfully setting seed and germinating saplings.  Some of these are not recommended to  be included in woodland, but  can be seen growing in hedgerows, nationwide.

NATIVE TREES AND SHRUBS.

NATIVE TREES

Common name Scientific name Description Habitat Other
Alder Alnus glutinosa

 

Fast growing tree that will reach 60m. Can be coppiced.

 

Grows on wet or flooded sites, often next to streams and ponds. Also on poor soils. Avoid acid soils, shady situations and very dry areas. A versatile tree that can be used on reclamation sites or as a pioneer species.
Ash Fraxinus excelsior Large tree, up to 45m, that can live for some 200 years. Grey/green bark with distinctive black buds in spring. Widespread, preferring limestone soils that are moist but well drained. Up to 450m altitude. Grows well in mixed woodland if not too shaded. Comes into leaf late and often drops leaves earlier than other species.
Aspen Populus tremula Very hardy tree that can reach 20m. Matures in 50 years. Suitable for a wide range of habitats from wet lowlands to mountain areas, but not too dry. Common in the Scottish Highlands besides streams and rivers.
Bay Willow Salix pentandra Usually grows to 10m. Native to North Wales and northwards Grows by rivers and other wet areas though not a common tree. Not shady sites Has broad glossy leaves which are sticky and fragrant when young. Good for bees.
Beech Fagus sylvatica Can grow up to 40m. Large species which casts deep shade on the woodland floor. Needs well-drained, sandy or chalky soils. Common in South East and Midlands Native only to southern England. Popular as hedging species
Bird Cherry Prunus padus Grows to 15m. Native of the north Midlands northwards. Common by streams in limestone areas such as north-west Yorkshire. Likes lime-rich soils. Attractive in June when in flower and in autumn with its yellow and amber colours. Fruits edible for birds.
Black Poplar Populus nigra Grows to 20-35m. Now quite Scarce in the countryside. Typically grows in damp soils, along stream and river sides. Also known as the Manchester poplar. Very resilient to pollution and fast growing so was once commonly planted in cities Now rare and care should be taken to find stock of local provenance.
Box Buxus sempervirens Usually grows to 2-5m. A dense evergreen that is often no more than a shrub. Typically grows on chalky soils such as the Chilterns, North Downs and the Cotswolds. Native to SE England The wood is the heaviest of the native timbers and does not float!
Crab Apple Malus sylvestris Grows to 2-10m. Spiny with white flowers. Found scattered in all areas including oak woodland, hedgerows and hilly chalky areas. The wild crab is one of at least four species from which the domestic apple is derived.
Crack Willow Salix fragilis Tall tree that grows to 10-18m. Has glossy elongated slender leaves Likes deep moist soils or riversides. Abundant in SE England and present throughout the UK. If twisted, brittle twigs crack at the base. In water it produces fine red, coral-like roots.
Downy Birch Betula pubescens Similar to the silver birch, although even less demanding. Quick growing to 25m, but short lived

showing signs of aging at 60 years.

Common on poorly drained soils and heaths, peat bogs and damper areas. Also by streams and pools. It is a pioneer species – often the first to colonise areas of cleared woodland or wasteland.
English Elm Ulmus procera Once a common species in wet woodland, hedgerows and banks. Grows to 30m Leaves dark green and rough above and pale beneath. Dark brown bark and cracked into rectangular plates Tree numbers were devastated during the 1970’s and 80’s with outbreak of Dutch Elm Disease, thought to have killed over 80% of population. Root stock often remains and suckers from this but gets infected again between 5-10 years as bark matures.
Field Maple Acer campestre The only native maple to Britain growing to 20m. Often used in hedges as either a shrub or tree Common on chalk or limestone soils in the south to the Midlands. Less common in northern England and Scotland A medium sized tough robust tree with colourful leaves that turn deep yellow in autumn. Fruit tinged pink in early summer
Goat Willow Salix caprea More commonly a shrub but can grow to 10m. Found in many areas. Hedgerows, woods and scrub, likes damp conditions. Very distinctive in spring when branches are covered in green and yellow catkins Distinctive silvery male catkins- gives the name pussy willow before bright yellow stamens emerge.
Hornbeam Carpinus betula A graceful tree that grows to a height of 30m. It also keeps its lower leaves in winter like beech. Prefers sheltered positions. Found in woods and hedges common in southern England. Grows well on heavy clay soils, as well as lighter soils but not acid sands. One of the hardest and strongest of native timbers. Historically used for cartwheels, still used for piano hammers.
Large leaved Lime Tilia platyphyllos Large tree that grows to 40m. Native to the Wye Valley and South Yorkshire. Commonly planted. Grows well in woods and often in limestone areas. Often found in parks and avenues. First lime to flower – fragrant blooms hang in clusters in late June.
Osier Salix viminalis Between 3 to 6m Commonly lining rivers and streams. Greyish – brown bark and fissured. Twigs are long and straight. Catkins in late February, March and early April. Plants can be cut annually to provide flexible shoots for basket weaving
Pendunculate Oak Quercus robur Usually grows to 20–35m known for its durability and longevity. Stalked fruit, the ‘peduncle’ gives it its name. Stalkless leaves Best on damp heavy clays but will grow on sandy soils. Typically found in the eastern lowlands of Britain. A robust tree that characterises the countryside. Supports a huge variety of insects throughout the year.
Purple Willow Salix purpurea Up to 5m Damp places, frequently beside lakes and rivers. Leaves are narrow and long- oblong in opposite pairs on the twigs. Grey Bark, twigs yellow or grey sometimes tinged with red or purple. Number of varieties grown for basket making across south of England
Rowan Sorbus aucuparia Small attractive tree that grows to 20m. Very hardy and occurs at a higher altitude than any other native tree – up to 1000m

 

Grows in many different soil conditions, though natural habitat is mountainous areas or lighter soils. Does well when planted in open woods. White flowers in early summer developing into red berries in autumn. High in vitamin C, they are eaten by blackbirds, thrushes and starlings. Fruit can also be used to make a jelly.
Scots Pine Pinus sylvestris Has widest range of any pine growing in forests, woods and plantations. Up to 40m in height. Hardy tree that grows throughout the UK. Good for growing on high ground, it also does well on heaths. Only native in Scottish Highlands. Once the favoured tree for plantations but now replaced by quicker growing Sitka spruce. Provides good winter interest in mixed woodland.
Sessile Oak Quercus petraea Majestic tree that grows to 40m. Not planted as often as Quercus robur. Stalkless fruit, stalked leaves. Grows well in woodland preferring high rainfall areas on lighter acid soils. Western and northern Britain Open birch and oak woods (upland oak) are the favoured habitat
Silver Birch Betula pendula Graceful tree that stands out in winter with its white trunk and branches, grows quickly when young and can reach 30m. Fairly short-lived species at about 70–100 years. Native throughout UK, preferring lighter soils and shallow peats. Common on dry heaths and open woodland. Pioneer species often first to colonise recently cleared areas. This is helped by its light seeds that are widely distributed by the wind.
Small Leaved Lime Tilia cordata The other native lime with downward dropping branches and heart-shaped leaves. Grows to about 30m in height. Found in mixed woodland on lime-rich soils. Fairly hardy tree in lowland areas. Often planted as a street tree or in avenues. Once thought to be more common than oak, it coppices well and is long lived. It spreads by suckers with some trees more than 1,000 years old. Bees are attracted to the flowers in early summer.
Smooth Leaved Elm Ulmus carpinifolia Up to 30m Native to Kent and East Anglia, rarer further north and west Upright Branches and dome shaped crown
Whitebeam (Common) Sorbus aria Grows to about 15m. Planted all over the country and is common in streets and gardens. Striking silver-coloured leaves in early summer. Native to chalk and limestone hills of southern England. Also does well on adjacent sandy soils. White flowers in early summer and red berries in autumn, which are taken by birds.
White Willow Salix alba Native all over Britain except north-west Scotland. Grows to about 25m. Green/grey elongated leaves. Common along lowland riversides and valleys, more frequent in southern areas. Likes damp or wet soils. Suitable for pollarding. Helps to stabilise riverbanks, though not as common as crack willow.
Wild Cherry (Gean) Prunus avium Native in all parts, this attractive tree has white flowers before the leaves appear in April–May. Grows to 30m. Found in woods and hedges. Prefers lime-rich and clay soils. Any position, but not deep shade. Also common as park or street tree. Attractive to bees.
Wild Pear Pyrus pyraster Small Tree up to 15m Rarer than the crab apple. Has quite spiny branches with particularly small and rounder fruits than other hybrids. Distinctive grey or brown bark which breaks into small rectangular plates. White flowers in April. Fruits ripen in November.
Wild Service Tree Sorbus torminalias A relative of rowan and whitebeam, grows up to 25m. Maple-like leaves which turn deep red in autumn. Grows on chalk, limestone and clay, traditionally from Kent up to Cumbria. More common in the west.

 

 

 

 

Edible red fruits are attractive to birds. Will only self-sow on land that has not been previously cultivated.
Wych Elm Ulmus glabra A dense canopied tree that can grow to 40m. Often grows by water and likes damp and shady spots. Is also found on hillsides in Scotland. Very hardy tree that copes well with polluted air, so is often used as a city park tree.
Yew Taxus baccata Very hardy evergreen tree that is commonly found in churchyards. Can grow up to 25m. Tolerant of all conditions except very wet ground. Prefers chalk and limestone, but found in oak woods on other soils. Our oldest living tree with some specimens more than 2,000 years old. Very strong, durable wood that was traditionally used to make longbows.
Hawthorn Crataegus monogyna Up to 12m Often used as hedging species and excellent stock barrier. Provides a good habitat for birds and berries in the autumn.  

 

NATIVE SHRUBS

Common name Scientific name Height Habitat
Alder buckthorn, Frangula alnus Up to 5m Mainly on moist, acidic soils in lowland England and Wales, but also on lime-rich fenland peat. Cannot tolerate permanent waterlogging.
Blackthorn or sloe Prunus spinosa Up to 4m Widespread and common except in northern Scotland on all except very acid or peaty soils. Intolerant of dense shade.

Valued for its fruits (sloes). Its dense, spiny growth also makes it ideal for nesting birds.

Bramble Rubus fruticosus Up to 2m Common in woodland, hedgerows and scrub throughout England and Wales. Thrives in well drained soils from acid to alkaline.
Buckthorn, purging Rhamnus catharticus Up to 6m rarely to 10m Confined to lime-rich soils on limestone and in fens in England and Wales.
Creeping Willow Salix repens Low growing not much above ground level. Locally dominant species in wet and dry sand dune stacks, acidic heathland and moorland.
Dog rose Rosa canina Up to 3m Commonly found in hedgerows, scrub and woodland in a wide range of soils throughout England and Wales up to 550m
Dogwood Cornus sanguinea Up to 5m Widespread in England and Wales, especially on lime-rich soils. Avoids dense woodland.
Elder Sambucus nigra Up to 10m Widespread except in northern Scotland. Frequently found on lime-rich soils, on disturbed areas and on land rich in nitrogen.
Guelder Rose Viburnum opulus Up to 4m Widespread, but rare in northern Scotland. Avoids very acid and very dry sites and dense woodland. Thrives on moist soils.
Hawthorn (Midland) Crataegus laevigata Up to 12m Similar in size to hawthorn. Leaves are different from Crataegus Monogyna and has two stoned fruit rather than one in. This is an ancient woodland indicator in many areas

Prefers shade in woods and heavy soils, typically in southern England

Many hybrids between this and hawthorn.

 

Hazel Corylus avellana Up to 6m Found in woodland, hedgerows and scrub. Common on chalk, limestone, neutral and mildly acid soils. A multi stemmed shrub, hazelnuts are good food source for squirrels and mice. Traditionally coppiced, often as understorey in oak woodland. Straight coppice stems are ideal for weaving into hurdles and other woodland products.
Holly Ilex aquifolium Can reach 20m height in some locations, Grows on almost any soils and in damp areas. Also found as an understorey in oak and beech woodland. Can be used a hedgerow species. Female tree produces red berries in autumn – food for some birds. May be sterile if planted in deep shade. Provides winter interest in woodland.

 

Juniper Juniperus communis Rarely more than 5m. Slow-growing evergreen shrub found in a wide range of habitats. Grows on chalk and limestone in open sunny places, but also in north on shallow wet acid peat and in shade of other conifers. Increasingly rare.

Has the most extensive range worldwide of any tree. Spans the landmass of the northern hemisphere.

Privet Ligustrum vulgare Up to 5m Widespread in England and Wales, especially in light woodland on thin, dry lime-rich soils. Cannot tolerate waterlogging.
Spindle Euonymous europaeus Up to 6m In England, Wales and Southern Scotland. Common in woods and scrub on lime-rich soils.
Strawberry tree Arbutus unedo Rarely exceeding 10m Evergreen tree or shrub. Only native in southwest Ireland. Slow growing and not long lived. Needs shelter to survive and is found mainly in Southern England and Ireland preferring drier situations.
Wayfaring Tree Viburnum lantana Up to 6m Confined to southern England and Wales, nearly always on dry lime-rich soils. Cannot grow on waterlogged soils or in dense shade.
Willow, grey Salix cinerea Usually to 5m rarely to 10m Very similar to Salix caprea, but classed as a shrub due to its size. Widespread. More tolerant of acid soils than S. caprea, but less tolerant of dry soils thriving in moist conditions.

NATIVE TREES FOR DIFFICULT CONDITIONS

Some sites may have special characteristics which will limit your choice of species.

Factor Wet Dry High altitude Frost pockets Exposure to wind Near to the sea Lime-rich (high pH) Acid (low pH)
  Waterlogging (permanent or temporary) prevents proper root functioning. Drought, lack of essential water (sites without extremes of pH) Cold, shorter growing season, frost and snow damage, high winds often wet and acidic sites Susceptibility to frost damage, especially to late spring frosts causing bud and leaf damage Drought, dessication caused by rapid transpiration, physical damage, often cold Salt in wind and spray affecting tree functioning, high winds Rich in calcium (and less commonly other elements, usually on or near limestone or chalk, often dry). Poor in essential nutrients commonly (a) wet, poorly drained moorland (b) very, dry, freely drained, sandy heathland
