Forest
Information about Forest
FOREST (an acronym for "Freedom Organisation for the Right to Enjoy Smoking Tobacco") is a United Kingdom political pressure group that campaigns for the right of people to smoke tobacco and opposes attempts to ban or reduce tobacco consumption. FOREST also disputes the health risks of smoking. Describing itself as the "voice and friend of the smoker",[1] FOREST is an astroturf group created and primarily funded by the tobacco industry.[2]
In 1987 Lord Harris of High Cross, general director of the Institute of Economic Affairs (1957-1989), was appointed chairman, a position he held until his death in October 2006, aged 81. A long-term pipesmoker and an outspoken critic of public smoking bans, Ralph Harris wrote numerous articles and essays on the subject of passive smoking (inhaling others' secondhand smoke, also known as "sidestream smoke" or "environmental tobacco smoke"), including "Smoking Out The Truth: a challenge to the Chief Medical Officer" (2005).[3]
FOREST spokesmen appear regularly on television and radio in the United Kingdom and are frequently quoted by British newspapers as representatives of smokers.[4][5][6][7]
According to the document "Minutes of the 11th Meeting of the Public Relations Sub-Committee of TAC Held at Glen House, Stag Place, London, SW1. On Tuesday, 5th August 1979" members of the Public Relations sub-committee of the Tobacco Advisory Committee, the British tobacco industry trade association, were minuted as saying, prior to the creation of FOREST:
In February 2006, FOREST lost its fight against a total ban on smoking in enclosed public places in England from Summer 2007. This includes all pubs, bars, cafés and restaurants, as well as workplaces and private members clubs. Similar bans have come into force in Northern Ireland (Spring 2007) and Wales (April 2007). Scotland introduced its own public smoking ban in March 2006. Despite this, FOREST says it will continue to fight for what it calls "freedom of choice". Current slogans include "Smokers are voters, too", "Enough is enough" and "Nanny state? No thanks".


A forest is an area with a high density of trees. There are many definitions of a forest, based on various criteria [10]. These plant communities cover large areas of the globe and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Historically, forest meant an uncultivated area legally set aside for hunting by feudal nobility, and these hunting forests were not necessarily wooded much if at all (see Royal Forest). However, as hunting forests did often include considerable areas of woodland, the word forest eventually came to mean wooded land more generally.
Forests sometimes contain many tree species within a small area (as in tropical rain and temperate deciduous forests), or relatively few species over large areas (e.g., taiga and arid montane coniferous forests). Forests are often home to many animal and plant species, and biomass per unit area is high compared to other vegetation communities. Much of this biomass occurs below-ground in the root systems and as partially decomposed plant detritus. The woody component of a forest contains lignin, which is relatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.
Forests are differentiated from woodlands by the extent of canopy coverage: in a forest the branches and foliage of separate trees often meet or interlock, although there can be gaps of varying sizes within an area referred to as forest. A woodland has a more continuously open canopy, with trees spaced further apart, which allows more sunlight to penetrate to the ground between them (see also savanna).
Among the major forested biomes are:
26 forest categories are used to enable the translation of forest types from national and regional classification systems to a harmonised global one:
Temperate and boreal forest types:
1 Evergreen needleleaf forest - Natural forest with > 30% canopy cover, in which the canopy is predominantly (> 75%) needleleaf and evergreen.

28 Native species plantation - Intensively managed forests with > 30% canopy cover, which have been planted by people with species that occur naturally in that country.
12* and 13* have been created as a result of data holdings which do not specify the forest type, hence 26 categories are quoted, not 28 shown here.[12]
The scientific study of forest species and their interaction with the environment is referred to as forest ecology, while the management of forests is often referred to as forestry. Forest management has changed considerably over the last few centuries, with rapid changes from the 1980s onwards culminating in a practice now referred to as sustainable forest management. Forest ecologists concentrate on forest patterns and processes, usually with the aim of elucidating cause and effect relationships. Foresters who practice sustainable forest management focus on the integration of ecological, social and economic values, often in consultation with local communities and other stakeholders.
Anthropogenic factors that can affect forests include logging, human-caused forest fires, acid rain, and introduced species, among other things. There are also many natural factors that can also cause changes in forests over time including forest fires, insects, diseases, weather, competition between species, etc. In 1997, the World Resources Institute recorded that only 20% of the world's original forests remained in large intact tracts of undisturbed forest [13]. More than 75% of these intact forests lie in three countries - the Boreal forests of Russia and Canada and the rainforest of Brazil. In 2006 this information on intact forests was updated using latest available satellite imagery.
Canada has about 4,020,000 km² of forest land. More than 90% of forest land is publicly owned and about 50% of the total forest area is allocated for harvesting. These allocated areas are managed using the principles of sustainable forest management, which includes extensive consultation with local stakeholders. About eight percent of Canada’s forest is legally protected from resource development (Global Forest Watch Canada)(Natural Resources Canada). Much more forest land — about 40 percent of the total forest land base — is subject to varying degrees of protection through processes such as integrated land-use planning or defined management areas such as certified forests (Natural Resources Canada). By December 2006, over 1,237,000 square kilometres of forest land in Canada (about half the global total) had been certified as being sustainably managed (Canadian Sustainable Forestry Certification Coalition). Clearcutting is usually the harvest method of choice and companies are required by law to ensure that harvested areas are adequately regenerated. Most Canadian provinces have regulations limiting the size of clearcuts, although some older clearcuts can range upwards of 110 km² (20,000 acres) in size which were cut over several years.
In the United States, most forests have historically been affected by humans to some degree, though in recent years improved forestry practices has helped regulate or moderate large scale or severe impacts. However the United States Forest Service estimates that every year about 6,000 km² (1.5 million acres) of the nation’s 3,000,000 km² (750 million acres) of forest land is lost to urban sprawl and development. It is expected that the South alone will lose 80,000 to 100,000 km² (20 to 25 million acres) to development. However, in many areas of the United States, the area of forest is stable or increasing, particularly in many northern states.
Globally two broad types of forests can be identified: natural and anthropogenic.
Natural forests contain mainly natural patterns of biodiversity in established seral patterns, and they contain mainly species native to the region and habitat. The natural formations and processes have not been affected by humans with a frequency or intensity to change the natural structure and components of the habitat.
Anthropogenic forests have been created by humans or sufficiently affected by humans to change or remove natural seral patterns. They often contain significant elements of species which were originally from other regions or habitats.

History
FOREST was officially founded in 1979 by former Air Chief Marshal Sir Christopher Foxley-Norris.In 1987 Lord Harris of High Cross, general director of the Institute of Economic Affairs (1957-1989), was appointed chairman, a position he held until his death in October 2006, aged 81. A long-term pipesmoker and an outspoken critic of public smoking bans, Ralph Harris wrote numerous articles and essays on the subject of passive smoking (inhaling others' secondhand smoke, also known as "sidestream smoke" or "environmental tobacco smoke"), including "Smoking Out The Truth: a challenge to the Chief Medical Officer" (2005).[3]
FOREST spokesmen appear regularly on television and radio in the United Kingdom and are frequently quoted by British newspapers as representatives of smokers.[4][5][6][7]
Funding
FOREST is an astroturf group created and primarily funded by the tobacco industry.[8] FOREST's website states that it is funded 'mainly' by the tobacco industry. [2]. Its establishent was planned by the Tobacco Advisory Committee, the British tobacco industry trade associationAccording to the document "Minutes of the 11th Meeting of the Public Relations Sub-Committee of TAC Held at Glen House, Stag Place, London, SW1. On Tuesday, 5th August 1979" members of the Public Relations sub-committee of the Tobacco Advisory Committee, the British tobacco industry trade association, were minuted as saying, prior to the creation of FOREST:
- Mr. Knowles said that a recent conversation with Geoffrey Evans indicated that 'Forest' would now not be launched before mid-June. It as felt that, in view of some of the reservations expressed about this organisation by PR agencies, the delay would not be to our disadvantage.
- Mr. Sanguinetti thought TAC should query the use of the name "Forest" in view of the unfortunate connotations that could be attached -- forest fires, backwoodsmen, etc. After discussion it was agreed that the Chairman should write to Sir Christopher Foxley Norris to let him know of our misgivings and propose a more straightforward title such as "Freedom to Smoke."
- Members discussed how TAC and the Companies should respond to press enquiries following the organisation's launch. The Chairman said he thought TAC should reply that while they were aware of its existence Glen House had no connection with the new organisation and that enquiries should be directed to member companies. Mr. Mulholland proposed that his company should reply that Forest was an independent organisation, that it seemed a good idea for it to support smokers and that the company had provided financial support and nothing more. [9]
Recent developments
In recent years FOREST has attracted the support of several high profile smokers including artist David Hockney, inventor Trevor Baylis, musician Joe Jackson, restaurateur and TV chef Antony Worrell Thompson, and Claire Fox, director of the Institute of Ideas. In September 2005 Hockney, Jackson and Fox all spoke at a fringe meeting organised by FOREST at the Labour Party conference in Brighton.In February 2006, FOREST lost its fight against a total ban on smoking in enclosed public places in England from Summer 2007. This includes all pubs, bars, cafés and restaurants, as well as workplaces and private members clubs. Similar bans have come into force in Northern Ireland (Spring 2007) and Wales (April 2007). Scotland introduced its own public smoking ban in March 2006. Despite this, FOREST says it will continue to fight for what it calls "freedom of choice". Current slogans include "Smokers are voters, too", "Enough is enough" and "Nanny state? No thanks".

A forest is an area with a high density of trees. There are many definitions of a forest, based on various criteria [10]. These plant communities cover large areas of the globe and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Historically, forest meant an uncultivated area legally set aside for hunting by feudal nobility, and these hunting forests were not necessarily wooded much if at all (see Royal Forest). However, as hunting forests did often include considerable areas of woodland, the word forest eventually came to mean wooded land more generally.
Distribution
Forests can be found in all regions capable of sustaining tree growth, at altitudes up to the tree line, except where natural fire frequency is too high, or where the environment has been impaired by natural processes or by human activities. As a general rule, forests dominated by angiosperms (broadleaf forests) are more species-rich than those dominated by gymnosperms (conifer, montane, or needleleaf forests), although exceptions exist (for example, species-poor aspen and birch stands in northern latitudes).Forests sometimes contain many tree species within a small area (as in tropical rain and temperate deciduous forests), or relatively few species over large areas (e.g., taiga and arid montane coniferous forests). Forests are often home to many animal and plant species, and biomass per unit area is high compared to other vegetation communities. Much of this biomass occurs below-ground in the root systems and as partially decomposed plant detritus. The woody component of a forest contains lignin, which is relatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.
Forests are differentiated from woodlands by the extent of canopy coverage: in a forest the branches and foliage of separate trees often meet or interlock, although there can be gaps of varying sizes within an area referred to as forest. A woodland has a more continuously open canopy, with trees spaced further apart, which allows more sunlight to penetrate to the ground between them (see also savanna).
Among the major forested biomes are:
- rain forest (tropical and temperate)
- taiga
- temperate hardwood forest
- tropical dry forest
Classification
Forests can be classified in different ways and to different degrees of specificity. One such way is in terms of the "biome" in which they exist, combined with leaf longevity of the dominant species (whether they are evergreen or deciduous). Another distinction is whether the forests composed predominantly of broadleaf trees, coniferous (needle-leaved) trees, or mixed.- Boreal forests occupy the subarctic zone and are generally evergreen and coniferous.
- Temperate zones support both broadleaf deciduous forests (e.g., temperate deciduous forest) and evergreen coniferous forests (e.g., Temperate coniferous forests and Temperate rainforests). Warm temperate zones support broadleaf evergreen forests, including laurel forests.
- Tropical and subtropical forests include tropical and subtropical moist forests, tropical and subtropical dry forests, and tropical and subtropical coniferous forests.
- Physiognomy classifies forests based on their overall physical structure or developmental stage (e.g. old growth vs. second growth).
- Forests can also be classified more specifically based on the climate and the dominant tree species present, resulting in numerous different forest types (e.g., ponderosa pine/Douglas-fir forest).
- 1 - Temperate needleleaf
- 2 - Temperate broadleaf and mixed
- 3 - Tropical moist
- 4 - Tropical dry
- 5 - Sparse trees and parkland
- 6 - Forest Plantations
26 forest categories are used to enable the translation of forest types from national and regional classification systems to a harmonised global one:

Forest management and Forest loss
Redwood tree in northern Califonia redwood forest, where many redwood trees are managed for preservation and longevity, rather than harvest for wood production.
The scientific study of forest species and their interaction with the environment is referred to as forest ecology, while the management of forests is often referred to as forestry. Forest management has changed considerably over the last few centuries, with rapid changes from the 1980s onwards culminating in a practice now referred to as sustainable forest management. Forest ecologists concentrate on forest patterns and processes, usually with the aim of elucidating cause and effect relationships. Foresters who practice sustainable forest management focus on the integration of ecological, social and economic values, often in consultation with local communities and other stakeholders.
Anthropogenic factors that can affect forests include logging, human-caused forest fires, acid rain, and introduced species, among other things. There are also many natural factors that can also cause changes in forests over time including forest fires, insects, diseases, weather, competition between species, etc. In 1997, the World Resources Institute recorded that only 20% of the world's original forests remained in large intact tracts of undisturbed forest [13]. More than 75% of these intact forests lie in three countries - the Boreal forests of Russia and Canada and the rainforest of Brazil. In 2006 this information on intact forests was updated using latest available satellite imagery.
Canada has about 4,020,000 km² of forest land. More than 90% of forest land is publicly owned and about 50% of the total forest area is allocated for harvesting. These allocated areas are managed using the principles of sustainable forest management, which includes extensive consultation with local stakeholders. About eight percent of Canada’s forest is legally protected from resource development (Global Forest Watch Canada)(Natural Resources Canada). Much more forest land — about 40 percent of the total forest land base — is subject to varying degrees of protection through processes such as integrated land-use planning or defined management areas such as certified forests (Natural Resources Canada). By December 2006, over 1,237,000 square kilometres of forest land in Canada (about half the global total) had been certified as being sustainably managed (Canadian Sustainable Forestry Certification Coalition). Clearcutting is usually the harvest method of choice and companies are required by law to ensure that harvested areas are adequately regenerated. Most Canadian provinces have regulations limiting the size of clearcuts, although some older clearcuts can range upwards of 110 km² (20,000 acres) in size which were cut over several years.
In the United States, most forests have historically been affected by humans to some degree, though in recent years improved forestry practices has helped regulate or moderate large scale or severe impacts. However the United States Forest Service estimates that every year about 6,000 km² (1.5 million acres) of the nation’s 3,000,000 km² (750 million acres) of forest land is lost to urban sprawl and development. It is expected that the South alone will lose 80,000 to 100,000 km² (20 to 25 million acres) to development. However, in many areas of the United States, the area of forest is stable or increasing, particularly in many northern states.
Globally two broad types of forests can be identified: natural and anthropogenic.
Natural forests contain mainly natural patterns of biodiversity in established seral patterns, and they contain mainly species native to the region and habitat. The natural formations and processes have not been affected by humans with a frequency or intensity to change the natural structure and components of the habitat.
Anthropogenic forests have been created by humans or sufficiently affected by humans to change or remove natural seral patterns. They often contain significant elements of species which were originally from other regions or habitats.

- 2006-01-13, Sciencedaily: Deep-rooted Plants Have Much Greater Impact On Climate Than Experts Thought Citat: "...The tap roots transfer rainwater from the surface to reservoirs deep underground and redistribute water...increases photosynthesis and the evaporation of water...by 40% in the dry season...During the wet season, these plants can store as much as 10% of the annual precipitation as deep as 13 metres (43 ft) underground, to be tapped during the dry months...tree roots acting like pipes to allow water to shift around much faster than it could otherwise percolate through the soil..."
