    • According to the Brazilian National System ofConservation Units, National Forests are areas withforest cover of predominantly native species and has asits basic objective the multiple sustainable use of theforest resources and scientific research, with emphasis onmethods of sustainable exploitation of native forests.
    •  The Brazilian forests are divided into four categoriesand many sub categories. The four major categories are:-I. Northern national forestII. Southern national forestIII. Northeast national forestIV. Southeast national forest
    •  Northern National forest Amapa Amazon Southern National forest Acungui Cacador Northeast National forest Araripe Contendas of Sincora Southeast National forest Capao Bonito Ipanema
    • Indonesia’s tropical forests are of global importance,covering over 98 million hectares (242,163,274 acre). Mostof Indonesia’s forests are found in the Indonesian half ofNew Guinea, and on the islands of Borneo and Sumatra.The forests of Indonesia represent 10% of the world’sremaining tropical forests. Indonesia’s forests are the secondlargest in the world after the forests of Brazil.
    •  Indonesia is one of the five most species-rich countries inthe world, with a high rate of endemic species. Twelve percent of all mammal species, 16% of reptileand amphibian species, and 17% of bird species arefound on the 17,000 islands that constitute Indonesia. The forests of Indonesia, along with their thousands ofplant and animal species, are being destroyed at analarming rate due to massive illegal logging and clearingfor palm oil plantations.
    •  The rapid deterioration of tropical forests is causingincalculable losses in terms of biodiversity and ispushing species such as the orangutan ever closer toextinction. After Malaysia and the United States, Indonesia hasthe third highest number of threatened species with 772species. New programmes and initiates taken are considered tobe a chance of recovery.
    •  The United States has 155 protected areas knownas National Forests covering 188,293,938 acres(761,999 km2). The National Forests are managed bythe U.S. Forest Service, an agency of the U.S.Department of Agriculture. In 1897, the Organic Act provided purposes for whichforest reserves could be established, including to protectthe forest, secure water supplies, and supply timber. Alaska has the most National Forest land with 21.9million acres (8.9 million ha), followed by California(20.8 million acres, 8.4 million ha) and Idaho (20.4million acres, 8.3 million ha).
    •  The land of USA support a number of types offorests :- Allegheny Forest in Pennsylvania Angeles Forest In California Angelina Forest In Texas Apache- Sit greaves in Arizona, New Mexico Apalachicola Forest In Florida Arapaho Forest In Colorado
    •  Over the last 20 years, India has reversed thedeforestation trend. Specialists of the United Nations report Indiasforest as well as woodland cover has increased. A2010 study by the Food and AgricultureOrganization ranks India amongst the 10 countrieswith the largest forest area coverage in the world(the other nine being Russian Federation, Brazil,Canada, United States of America, China,Democratic Republic of the Congo, Australia,Indonesia and Sudan). India is also one the top 10 countries with thelargest primary forest coverage in the world,according to this study.
    •  From 1990 to 2000, FAO finds India was the fifth largestgainer in forest coverage in the world; while from 2000 to2010, FAO considers India as the third largest gainer inforest coverage. Some 500,000 square kilometers, about 17 percent of Indiasland area, were regarded as Forest Area in the early 1990s.In FY 1987, however, actual forest cover was 640,000square kilometers. Some claim, that because more than 50percent of this land was barren or bush land, the area underproductive forest was actually less than 350,000 squarekilometers, or approximately 10 percent of the countrys landarea. Indias 0.6 percent average annual rate of deforestation foragricultural and non-lumbering land uses in the decadebeginning in 1981 was one of the lowest in the world andon a par with Brazil.
    •  India supports five types of forests:-I. Tropical evergreen forestII. Tropical deciduous forestIII. Thorn forestIV. Montane forestV. Mangrove forest
    • The United Kingdom is a good place to practiceforestry, because the British Isles are ideal for treegrowth, thanks to their mild winters, plentifulrainfall, 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 thoseof Sweden and five times those of Finland. In theabsence of people, much of Great Britain would becovered with mature oaks, except for Scotland.
    •  Britains native tree flora comprises 32 species, of which29 are broadleaves. Britains industry and populace uses at least 50 milliontones of timber a year. Paper and paper products makeup more than half the wood consumed in Britain byvolume.UK set up the Independent Panel on Forestry led by RtRev James Jones, the Bishop of Liverpool. This bodypublished its report in July 2012. Among othersuggestions, it recommended that the forested portionof England should rise to 15% of the countrys land areaby 2060.
