Forestry in the United Kingdom

The United Kingdom,[Notes 1] being in the British Isles, is ideal for tree growth, thanks to its mild winters, plentiful rainfall, fertile soil and hill-sheltered topography. Growth rates for broadleaved (hardwood) trees exceed those of mainland Europe, while conifer (softwood) growth rates are three times those of Sweden and five times those of Finland. In the absence of people, much of Great Britain would be covered with mature oaks, except for Scotland. Although conditions for forestry are good, trees do face damage threats arising from fungi, parasites and pests.[1][2]

Epping Forest in 2008

Nowadays, about 12.9% of Britain's land surface is wooded. The country's supply of timber was severely depleted during the First and Second World Wars, when imports were difficult, and the forested area bottomed out at under 5% of Britain's land surface in 1919. That year, the Forestry Commission was established to produce a strategic reserve of timber. Other European countries average from 25% to 72% (Finland) of their area as woodland.[3][4][5][6][7]

Of the 31,380 square kilometres (12,120 sq mi) of forest in Britain, around 30% is publicly owned and 70% is in the private sector.[Notes 2] More than 40,000 people work on this land. Conifers account for around one half (51%) of the UK woodland area, although this proportion varies from around one quarter (26%) in England to around three quarters (74%) in Scotland.[8] Britain's native tree flora comprises 32 species, of which 29 are broadleaves. Britain's industry and populace uses at least 50 million tonnes of timber a year. More than 75% of this is softwood, and Britain's forests cannot supply the demand; in fact, less than 10% of the timber used in Britain is home-grown. Paper and paper products make up more than half the wood consumed in Britain by volume.[3][9][10][11]

In October 2010, the new coalition government of the UK suggested it might sell off around half the Forestry Commission-owned woodland in the UK. A wide variety of groups were vocal about their disapproval, and by February 2011, the government abandoned the idea. Instead, it set up the Independent Panel on Forestry led by Rt Rev James Jones, then the Bishop of Liverpool. This body published its report in July 2012. Among other suggestions, it recommended that the forested portion of England should rise to 15% of the country's land area by 2060.[7]

Background

A member of the Women's Timber Corps in the Second World War

Throughout most of British history, people have most commonly created farmland at the expense of forest. Furthermore, variations in the Holocene climate have led to significant changes in the ranges of many species. This makes it complex to estimate the likely extent of natural forest cover. For example, in Scotland four main areas have been identified: oak dominated forest south of the Highland Line, Scots Pine in the Central Highlands, hazel/oak or pine/birch/oak assemblages in the north-east and south-west Highlands, and birch in the Outer Hebrides, Northern Isles and far north of the mainland. Furthermore, the effects of fire, human clearance and grazing probably limited forest cover to about 50% of the land area of Scotland even at its maximum. The stock of woodland declined alarmingly during the First World War[12] and "a Forestry Subcommittee was added to the Reconstruction Committee to advise on policy when the war was over. The Subcommittee, better known as the Acland Committee after its chairman Sir A. H. D. Acland, came to the conclusion that, in order to secure the double purpose of being able to be independent from foreign supplies for three years and a reasonable insurance against a timber famine, the woods of Great Britain should be gradually increased from three million acres to four and three quarter millions at the end of the war".[13] Following the Acland Report of 1918 the Forestry Commission was formed in 1919 to meet this need. State forest parks were established in 1935.[14][15][16][5]

Emergency felling controls had been introduced in the First and Second World Wars, and these were made permanent in the Forestry Act 1951. Landowners were also given financial incentives to devote land to forests under the Dedication Scheme, which in 1981 became the Forestry Grant Scheme. By the early 1970s, the annual rate of planting exceeded 40,000 hectares (99,000 acres) per annum. Most of this planting comprised fast-growing conifers. Later in the century the balance shifted, with fewer than 20,000 hectares (49,000 acres) per annum being planted during the 1990s, but broadleaf planting actually increased, exceeding 1,000 hectares (2,500 acres) per year in 1987. By the mid-1990s, more than half of new planting was broadleaf.[9][17]

Historical woodland cover of England. The Domesday Book of 1086 indicated cover of 15%, "but significant loss of woodland started over four thousand years ago in prehistory". By the beginning of the 20th century this had dropped to 5%. The government believes 12% can be reached again by 2060.[18]

In 1988, the Woodland Grant Scheme replaced the Forestry Grant Scheme, paying nearly twice as much for broadleaf woodland as conifers. (In England, the Woodland Grant Scheme was subsequently replaced by the English Woodland Grant Scheme, which operates six separate kinds of grant for forestry projects.)[19][20] That year, the Farm Woodlands Scheme was also introduced, and replaced by the Farm Woodland Premium Scheme in 1992.[21] In the 1990s, a programme of afforestation resulted in the establishment of Community Forests and the National Forest, which celebrated the planting of its seven millionth tree in 2006.[22] As a result of these initiatives, the British Isles are one of a very few places in the world where the stock of forested land is actually increasing, though the rate of increase has slowed since the turn of the millennium.[23]

England Rural Development Programme is the current overarching grants scheme that includes money for forested land within it.

Ancient woodland

Main article: Ancient woodland

Ancient woodland is defined as any woodland that has been continuously forested since 1600. It is recorded on either the Register of Ancient Semi-Natural Woodland or the Register of Planted Woodland Sites. There is no woodland in Britain that has not been profoundly affected by human intervention. Apart from certain native pinewoods in Scotland, it is predominantly broadleaf. Such woodland is less productive, in terms of timber yield, but ecologically rich, typically containing a number of "indicator species" of indigenous wildlife. It comprises roughly 20% of the forested area.[24][25]

Native and historic tree species

Britain is relatively impoverished in terms of native species. For example, only thirty-one species of deciduous tree and shrub are native to Scotland, including ten willows, four whitebeams and three birch and cherry.[26][Notes 3] This is a list of tree species that existed in Britain before 1900. The sheer number of tree species planted subsequently precludes a complete list.[Notes 4]

Threats

White Rot Fungus, Heterobasidion annosum

Most serious disease threats to British woodland involve fungus. For conifers, the greatest threat is White Rot Fungus (Heterobasidion annosum). Dutch Elm Disease arises from two related species of fungi in the genus Ophiostoma, spread by Elm Bark Beetles and acute oak decline has a bacterial cause. Another fungus, Nectria coccinea, causes Beech bark disease, as does Bulgaria polymorpha. Ash canker results from Nectria galligena or Pseudomonas savastanoi, and most trees are vulnerable to Honey Fungus (Armillaria mellea). The oomycete Phytophthora ramorum (responsible for "Sudden oak death" in the USA) has killed large numbers of Japanese Larch trees in the UK.[27][28][29][30][31][32][33]

Beetles, moths and weevils can also damage trees, but the majority do not cause serious harm. Notable exceptions include the Large Pine Weevil (Hylobius abietis), which can kill young conifers, the Spruce Bark Beetle (Ips typographus) which can kill spruces, and the Cockchafer (Melolontha melolontha) which eats young tree roots and can kill in a dry season. Rabbits, squirrels, voles, field mice, deer, and farm animals can pose a significant threat to trees. Air pollution, acid rain, and wildfire represent the main environmental hazards.[34][35]

Timber industry

In 2013, the UK produced 3,582,000 cubic metres of sawn wood, 3,032,000 cubic metres of wood-based panels and 4,561,000 tonnes of paper and paperboard. The UK does not produce enough timber to satisfy domestic demand, and the country has been a net importer of timber and paper for many years. In 2008 the country imported sawn and other wood to a value of £1,243 million and exported £98 million; imported £832 million of wood-based panels and exported £104 million; and imported paper and paper-based products to a value of £4,273 million and exported £1,590 million. In 2012 approximately 15,000 people were employed in forestry and 26,000 in primary wood production in the country, resulting in a gross value added to the country of £1,936 million. With the ongoing closure of sawmills, the biomass industry is likely to be a key driver for future growth.[3][36][37][38][39][7]

Planting

Successful forestry requires healthy, well-formed trees that are resistant to diseases and parasites. The best wood has a straight, circular stem without a spiral grain or fluting, and small, evenly spaced branches. The chances of achieving these are maximised by planting good-quality seed in the best possible growing environment.[40]

Stewardship and management

The Forestry Commission was established in 1919, in order to address a lack of timber following the First World War: at this point Britain had only 5% of its original forest cover left and the government at that time wanted to create a strategic resource of timber.[41] Since then forest coverage has doubled and the commission's remit expanded to include greater focus on sustainable forest management and maximising public benefits. Woodland creation continues to be an important role of the commission, however, and works closely with government to achieve its goal of 12% forest coverage by 2060,[42] championing initiatives such as The Big Tree Plant and Woodland Carbon Code. Originally, the commission operated across Great Britain, however in 2013 Natural Resources Wales took over responsibility for Forestry in Wales,[43] whilst two new bodies (Forestry and Land Scotland and Scottish Forestry) were established in Scotland on 1 April 2019.[44] The Commission retains responsibility for forestry in England, as well as co-coordinating international forestry policy support and certain plant health functions in respect of trees and forestry across the UK.[45] The Forestry Commission is also the government body responsible for the regulation of private forestry in England; felling is generally illegal without first obtaining a licence from the Commission.[46] The Commission is also responsible for encouraging new private forest growth and development. Part of this role is carried out by providing grants in support of private forests and woodlands.

Natural Resources Wales (Welsh: Cyfoeth Naturiol Cymru) is a Welsh Government sponsored body, for the management of all the natural resources of Wales. It was formed from a merger of the Countryside Council for Wales, Environment Agency Wales, and the Forestry Commission Wales, and also assumes some other roles formerly taken by Welsh Government.[47] Other organisations working in Wales to improve the management of Welsh woodlands and forests include Confor[48], Coed Cymru[49] and Woodknowledge Wales.[50]

In Scotland, both Forestry and Land Scotland and Scottish Forestry are executive agency of the Scottish Government.[51] The key functions of Forestry and Land Scotland (FLS) are to look after the national forest estate, including unforested land within this portfolio, and to produce and supply timber. It is expected to enhance biodiversity, increase public access to the outdoors, encourage tourism and support the rural economy.[52] Scottish Forestry is responsible for regulation, policy and support to landowners, including regulation of FLS.[44][51]

The Forest Stewardship Council, more specifically FSC UK, sets forest management standards for the UK, promotes the system and provides an information service. It looks at the environmental, social and economic impacts of the timber industry.

Transportation

A timber train at Greenholme, near Kendal

Currently, the vast majority of Britain's timber uses road haulage. As forests are located in rural areas, the heavy timber vehicles have severely damaged many single lane tracks, especially in the Highlands. In order to combat this, companies are being forced to provide funding for repairs, as well as using alternative transport systems such as rail and coastal shipping. Despite the number of forest railways plummeting after the Beeching Axe, rail's share of timber transport has risen from 3% in 2002 with the opening of new lines in Devon, the Pennines, Scotland and South Wales by Colas Rail.[53][54][55][56]

Land values

The price of woodland has risen out of proportion to its productivity, and in 2012 reached peak prices over £10,000 per acre. Woodland prices are affected by its very favourable tax treatment and its high amenity value.[7]

HM Land Registry records purchases by way of conveyance, but where land has not changed hands since the Land Registry was established in 1862, no records exist. Two attempts have been made to take a complete census of ownership (the Domesday Book in 1086 and a census in 1873) but both contain significant omissions and are extremely dated besides; and much of the forested land is on long-established estates where ownership is not recorded on any register that can be examined. Often-quoted figures for England come from the Forestry Commission, National Inventory of Woodland and Trees (1998), which claims the breakdown is as follows: Private: Personal: 47.1% Business (including pension funds) 14.3% Public: Forestry Commission 21.8% Other central government: 2.7% Local authority 6% Charity 6.7% Forestry or timber business 0.7%
