Goat Willow

Scientific Name: 
Salix caprea

Goat Willow is a large shrub willow found in ditches, reedbeds, wet woodland and urban waste ground. It is one of the UK's commonest willows and is known for the fluffy, silver-grey male catkins - or 'pussy willows' - that appear in January and turn bright yellow in March.

How to identify: 
Goat Willow can be distinguished from other scrub willows by its broad leaves (twice as broad as long) that have thick silky hairs on their undersides.
Where to find it: 
Widespread.

Crack Willow

Scientific Name: 
Salix fragilis

Crack Willow is a large willow tree found along riverbanks, around lakes and in wet woodland. It is often planted alongside rivers and dykes to stabilise their banks and dykes, and is usually pollarded to allow light through to the water. These pollards can be contorted and gnarled, and often so full of crevices that other species start to grow from them such as Ash and Holly. Crack Willow is so-named because its trunk can grow so fast that it is liable to split open under its own weight.

How to identify: 
Crack Willow is often pollarded with a gnarled, cracked trunk. It has long, dark green leaves which are glossier than those of the White Willow, and have more jagged teeth along the edges.
Where to find it: 
Widespread.

White Willow

Scientific Name: 
Salix alba

White Willow is a large willow tree found along riverbanks, around lakes and in wet woodland. Its flowers appear in spring and its male catkins are long and yellow.

How to identify: 
The White Willow can appear silvery-white due to the colour of its silky, narrow leaves. It has upswept branches and often leans. White Willow can be distinguished from Crack Willow by their shorter leaves which have hairy undersides.

Hybrid Black Poplar

Scientific Name: 
Populus x canadensis

The Hybrid Black Poplar is a commonly planted and naturalised variety of the Wild Black Poplar, and is frequently seen along riversides, roadsides and in parks. Grown for ornamental planting and timber production, it originated in France in the 18th century.

How to identify: 
Taller and straighter than the native Wild Black Poplar, the Hybrid Black Poplar has slightly rounder leaves which are dark green above and pale below, giving the tree a silvery appearance.
Where to find it: 
Widespread.
How people can help: 

Wild Black Poplars have suffered severe declines and it is estimated that only 8,000 now exist in the UK, with only 400 being female. Their decline has been caused by a lack of suitable wetland habitat, the removal of trees because their seeds have been considered a nuisance, and the extensive planting of hybrids. But The Wildlife Trusts are helping this species through veteran tree surveys, planting and sympathetic wetland management. You can help by supporting your local Trust and becoming a member.

Statistics: 
Height: up to 30m
Conservation status: 
Common.
Did you know?: 
The 'Railway Poplar' is a cultivar of the Hybrid Black Poplar so-named because it is the most frequently planted variety alongside railways.

Black Poplar

Scientific Name: 
Populus nigra ssp. betulifolia

The native Wild Black Poplar is a massive tree with a thick, fissured trunk that can be found in river valley floodplains, around gravel pits and along ditches. It is particularly prevalent in Shropshire, Cheshire, Somerset, the Vale of Aylesbury and East Anglia, but populations have declined massively over the years. Yet Black Poplars have formed an important part of our landscape and culture for centuries, from providing landmarks and focus for celebration, to inspiring the famous painter, Constable, and providing timber for floorboards.

How to identify: 
Wild Black Poplar can be distinguished from the various other varieties of poplar by its deeply fissured bark, the knobbly 'bosses' on its trunk and its spreading branches which often touch the ground, before sweeping upwards again in a mass of twigs. It has red catkins.
Where to find it: 
Found in England and Wales; widespread but uncommon. It may be found and is perhaps native to some parts of Ireland.
How people can help: 

Wild Black Poplars have suffered severe declines and it is estimated that only 8,000 now exist in the UK, with only 400 being female. Their decline has been caused by a lack of suitable wetland habitat, the removal of trees because their seeds have been considered a nuisance, and the extensive planting of hybrids. Now, many of our Wild Black Poplars are getting old, without new generations to replace them. But The Wildlife Trusts are helping this species through veteran tree surveys, planting and sympathetic wetland management. You can help by supporting your local Trust and becoming a member.

Statistics: 
Height: 20-25m
Conservation status: 
Rare. Receives general protection in the UK under Section 13 of the Wildlife and Countryside Act, 1981, which prohibits the unauthorised uprooting of any wild plant species.
Did you know?: 
To reproduce, male and female Wild Black Poplars need to be sited close to each other. The fertilised seeds need to fall on damp ground, making river valleys perfect places for this species. But the drainage of the land for agricultural has made it difficult for these wetland trees and they have slowly disappeared from the landscape.

Aspen

Scientific Name: 
Populus tremula

Aspen is a small, slender poplar tree of heathland, woodland and wet woodland, and can particularly be found in Scotland and Northern Ireland. Aspen are known as 'colonial trees' because they spread by growing suckers from their roots from which new shoots appear. They can form extensive groves in this many. However, Aspen also reproduce sexually through wind pollination: flowers can be seen from February to March and the male and female catkins appear on separate trees.

How to identify: 
Aspen can be recognised by its greyish bark, hanging catkins and its small, rounded leaves with pale undersides that flutter distinctively in the wind.
Where to find it: 
Widespread.
How people can help: 

The Wildlife Trusts manage many woodland nature reserves sympathetically for wildlife by ensuring a range of appropriate tree species, such as Aspen, provide food and shelter. You can help too: volunteer for The Wildlife Trusts and you could be involved in everything from traditional forest crafts to raising awareness about woodland wildlife.

Statistics: 
Height: up to 20m
Conservation status:

Scots Pine

Scientific Name: 
Pinus sylvestris

Scots Pine is the native pine tree in Scotland and has been widely planted elsewhere in the UK, too. During the medieval ages, a great pine forest stretched across most of the Highlands, but by the 17th century it was disappearing as timber was used for ship-building and charcoal. Although the late 20th century saw just a fraction of the original forest left standing, regeneration has now started to occur, especially in areas fenced off from browsing deer.

How to identify: 
Scots Pine is a tall, straight pine tree with distinctive orange-brown scaly bark. Its blue-green needles appear in pairs and can be up to 7cm long. Male cones are yellow and female cones are green, maturing to grey-brown.
Where to find it: 
Native in the Highlands of Scotland, but widely planted elsewhere.
How people can help: 

Despite massive clearances of Scots Pine forest in the Highlands, this native tree is now making a comeback which is good news for wildlife. The forests provide shelter for all kinds of species, and the seeds of the pine cones are a favourite food of threatened Red Squirrels and endemic Scottish Crossbills. With the help of an army of volunteers, The Wildlife Trusts manage many woodland nature reserves for the benefit of wildlife - join us and you could be involved in everything from traditional forest crafts to raising awareness about woodland animals.

Statistics: 
Height: up to 40m Pine cone length: 3-7.5cm
Conservation status:

Did you know?: 
Scots Pine plays host to a whole range of species, from Stump Lichens and Scottish Wood Ants that live on and under the bark, to majestic Ospreys and Golden Eagles that nest in its level branches.

Sitka Spruce

Scientific Name: 
Picea sitchensis

The Sitka Spruce is a tall, evergreen conifer originally from the west coast of North America. It was introduced into the UK in 1831 and has become our most widely planted forest tree. Between the 1950s and 1980s, it was notoriously planted in large, regimented, dark and uniform forests.

How to identify: 
Spruce trees differ from firs by having downwards hanging cones, and from pine trees by having shorter needles. The Sitka Spruce has shorter cones than the Norway Spruce.
Where to find it: 
Widespread, planted for forestry.
How people can help: 

Although plantations of introduced tree species are often considered to be poor for biodiversity, they can, in fact, support a range of wildlife from Red Squirrels to Firecrests. The Wildlife Trusts manage many woodland nature reserves sympathetically for wildlife by ensuring a range of appropriate tree species provide food and shelter. You can help too: volunteer for The Wildlife Trusts and you could be involved in everything from traditional forest crafts to raising awareness about woodland wildlife.

Statistics: 
Height: up to 60m Pine cone length: 10cm

Norway Spruce

Scientific Name: 
Picea abies

The Norway Spruce is a tall, evergreen conifer, originally from Scandinavia that was introduced into the UK in the 16th century. Familiar to us all as the traditional 'Christmas tree', the Norway Spruce is a common sight across the UK's landscape, cultivated in plantations for the Christmas tree market and for timber products.

How to identify: 
Spruce trees differ from firs by having downwards hanging cones, and from pine trees by having shorter needles. The Norway Spruce has longer cones than the Sitka Spruce; the female cones are reddish-brown and cigar-shaped.
Where to find it: 
Widespread, planted for forestry particularly in the lowlands.
How people can help:

European Larch

Scientific Name: 
Larix decidua

The European Larch is an unusual conifer as it is deciduous. It has small cones on brittle twigs which start of as green and red, but turn brown as they mature, eventually opening their 'scales' to release the seeds inside. In spring, the needles are bright green but they turn golden yellow in the autumn, before they drop.

How to identify: 
The European Larch can be recognised by the clusters or 'tufts' of short needles on its twiggy branches, and the small, upright cones that look reddish before hardening. There is usually a thick layer of shed needles beneath the tree as well.
Where to find it: 
Widespread, planted for forestry.
How people can help:
