Forestry in the United Kingdom
Forestry is the management of trees and forests for environmental or economic gain. The United Kingdom[Notes 1] is a good place to practise forestry, because the British Isles are ideal for tree growth, thanks to their 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.
Nowadays, about 12% of Britain's land surface is wooded. This area is increasing. 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. However, the recovery is still very much in progress. Other European countries average from 25% to 37% of their area as woodland.
Of the 23,000 square kilometres (8,900 sq mi) of forest in Britain, around 40% is publicly owned and 60% is in the private sector.[Notes 2] More than 40,000 people work on this land. Broadleaves account for 29% of Britain's woodlands, the rest being conifers, but considering only England, the figures are 55% broadleaf and 45% conifer. 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.
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.
Throughout most of British history, the trend has been to create 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 and at the end of the war the Acland Report recommended that Britain should secure a strategic reserve of timber. The Forestry Commission was formed to meet this need. State forest parks were established in 1935.
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.
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.) That year, the Farm Woodlands Scheme was also introduced, and replaced by the Farm Woodland Premium Scheme in 1992. 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. 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.
England Rural Development Programme is the current overarching grants scheme that includes money for forested land within it.
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 2.5% of the forested area.
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.[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]

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.
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 fire represent the main environmental hazards.
In 2009, the UK produced 2,818,000 cubic metres of sawn wood, 2,565,000 cubic metres of wood-based panels and 4,983,000 cubic metres 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 2007 approximately 42,000 people were employed in forestry and primary wood production in the country, resulting in a gross value added to the country of £2,051 million. The biomass industry is likely to be a key driver for future growth.
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.
Commercial seed is relatively inexpensive,[Notes 5] but some foresters still prefer to collect their own seed. This should be done in dry weather, the seed kept in a well-ventilated place away from damp; broadleaved seeds do not keep well in long-term storage (apart from oak, sweet chestnut and sycamore, which can be kept). Conifer seed does tend to be storable. Stored seed is best pre-treated by being chilled and moistened before planting.
Tree breeding programmes, to ensure the best seed, are hampered by the trees' long life-cycles. However, particularly since the 1950s, the Forestry Commission among other organisations has been running a programme of breeding, propagation, induced flowering and controlled pollination with the aim of producing healthy, disease-resistant, fast-growing stock.
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.

- The United Kingdom (sometimes abbreviated to UK) is a political unit (specifically a country), the British Isles is a geographical unit (the archipelago lying off the northwest coast of Europe), and Great Britain is the name of the largest of those islands. In this article "Great Britain" is sometimes abbreviated to "Britain". The adjective "British" can mean either the political or the geographical entity.
- In fact, this is not easy to establish. There is no complete register of who owns land in the United Kingdom. (Nix et al. 1999, p. 2.) 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:
Business (including pension funds) 14.3%
Forestry Commission 21.8%
Other central government: 2.7%
Local authority 6%
Forestry or timber business 0.7%
