Different types of forests and their forms of usage.

frith) is an area with a high density of trees. Forests cover approximately 30% of land and 9.4% of all the planet earth. They are also responsible for regulating our planet's climate and act as large purifiers of airs, by absorbing carbon dioxide, and giving out oxygen. Different types of forests Forests are divided into following main types: o Tropical forest o Subtropical forest o Plantations o Boreal forest o Temperate forest o Seasonal or monsoon forest Tropical and Subtropical Forests Tropical and subtropical forests, also known as rainforests or tropical rainforests, are lavish and ample forests with broad leave tree. They are mostly found at lowlands near the equator - Asia, Africa, South & Central America and on many of the Pacific Islands. Almost 50% forests of the world are tropical and subtropical in nature.

1,500 lichens and nearly 1,000 bryophytes. The total number of vascular species is low by world standard but lichens and bryophytes are abundant and the latter form a population of global importance. Various populations of rare fern exist, although the impact of 19th century collectors threatened the existence of several species. The flora is generally typical of the north west European part of the Palearctic ecozone and prominent features of the Scottish flora include boreal Caledonian forest (much reduced from its natural extent), heather moorland and coastal machair. In addition to the native varieties of vascular plants there are numerous nonnative introductions, now believed to make up some 43% of the species in the country. The are a variety of important trees species and specimens; a Douglas Fir near Inverness is the tallest tree in the United Kingdom and the Fortingall Yew may be the oldest tree in Europe.

Report Of Canada

Canada's largest geographical feature, it stretches east to Labrador, south to Kingston on Lake Ontario and northwest as far as the Arctic Ocean. The Shield is considered to be the nucleus of the North American continent and is made up of roots of ancient mountains. Its gneiss and granite rocks are 3.5 billion years old, three quarters the age of the Earth. Scraped by the advance and retreat of glaciers, the Shield has only a thin layer of soil that supports a boreal forest of spruce, fir, tamarack and pine. The region is a storehouse of minerals, including gold, silver, zinc, copper and uranium, and Canada's great mining towns are located there: Sudbury and Timmins in Ontario, Val d'Or in Quebec, and Flin Flon and Thompson in Manitoba. St. Lawrence Lowlands - The Great Lakes Southern Quebec and Ontario, the industrial heartland of Canada, contain Canada's two largest cities, Montreal and Toronto

Sea and Black Sea. The Czech Republic also leases the Moldauhafen, a 30,000-square-metre (7.4-acre) lot in the middle of the Hamburg Docks, which was awarded to Czechoslovakia by Article 363 of the Treaty of Versailles, to allow the landlocked country a place where goods transported down river could be transferred to seagoing ships. Phytogeographically, the Czech Republic belongs to the Central European province of the Circumboreal Region, within the Boreal Kingdom. According to the World Wide Fund for Nature, the territory of the Czech Republic can be subdivided into four ecoregions: the Central European mixed forests, Pannonian mixed forests, Western European broadleaf forests and Carpathian montane conifer forests. There are four national parks in the Czech Republic. The oldest is Krkonose National Park (Biosphere Reserve), Sumava National Park (Biosphere Reserve), National Park Podyjí, Ceské Svcarsko National Park.

Ontario to the frigid Arctic plains of the Northern Canada, from the wet temperate rainforests of the west coast to the arid deserts, badlands and tundra plains, the biodiversity of Canada's plants is extensive. Many of the plants seen in Canada are introduced, either intentionally or accidentally. Canada offers a wide range of habitats across varied vegetation. Arctic Tundra can be found in Canada's north which leads south into boreal forests which is most typical of Canada and covers more of the country than any other type of vegetation. The Maritimes are home to the Acadian forests which are made up from spruce, for, birch, pine and maple trees. West of the Maritimes in Quebec and Ontario are the Laurentian Forests and Mountains leading into the Canadian Shield in the north and the Great Lakes in the south and west of Ontario
