We have four seasons in Estonia. The air is very humid and it rains quite often, especially in spring and autumn. We usually have long winters and plenty of snow, but sometimes we haven't even had snow. Summers are is mostly warm and beautiful in Estonia. Estonia is well known for it's amazing countryside. We don't have any big mountains, but we do have over a thousand islands and over a thousand lakes that are worth seeing. One fifth of Estonia is covered by wetlands and almost one forth of the territory is forested. We also have four spectacular national parks and more than 50 nature reserves. The capital of Estonia is Tallinn. Tallinn is best known for it's old town. There are many churches, medieval buildings, the Town city Hhall and it's all bounded by the town wall and gatetowers. The national symbol of Estonia is a blue, black and white striped flag and the national emblems are a cornflower and a chimney swallow.

The sky over Estonia is cloudy for about half the year, and the hilly southeast region experiences up to 750 mm of precipitation due to Estonia's maritime climate. Nature While seven thousand rivers and streams carry rainwater to the sea, bogs and wooded swamplands of different types cover over one fifth of the country -- a world index topped only by the northern neighbour, Finland. Various kinds of forests comprise slightly under half of Estonia's territory. Wetlands, together with primeval forests, represent preserved communities which have for the most part been destroyed in Europe. More than 1000 lakes (5 per cent of the Estonian territory) dot the countryside, which is relatively flat -- almost two thirds of the territory lies less than 50 m above sea level. The highest point is Suur Munamägi, 317 m above sea level, in the southeast of the country. Estonia is the home of several mammals as well as plant species that are extinct or

The flag became associated with Estonian nationalism and was used as the national flag when the Declaration of Independence was issued in 1918. During occupations, the flag has been banned several times. In a good, snowy winter, the Estonians' favourite leisure activity is probably skiing. In spring, Estonians often leave the cities for the weekends. Many families have a cottage in the countryside. As approximately half of Estonia is covered with woodlands and wetlands, going for long walks in the wild is also very popular among Estonians. Since a forest is seldom farther away than a half-an-hour's drive, people often go there for a mushroom hunt, to watch the beautiful wildlife or just for a relaxing walk. Regardless of their age or whether they live in a city or the countryside, an important weekend ritual for many Estonians is the Saturday sauna. Christmas time is the most important holiday celebrated in Estonia. Like in other Nordic
Sosnovski hogweed is poisonous and is even dangerous to people and it spreads very fast. Landscape. Estonia's landscape is quite even. The last Ice Age made a big impact on the current relief and also the sea that covered the country once. The southern and central part of Estonia is hillier than the northern and western part. The northern and western parts are quite low. 50% of Estonia is covered with forests and 30% is covered with wetlands. Estonian landscape features numerous meteorite craters. The Endla Nature Reserve in Central Estonia is an uninhabited wetland covered in a variety of vegetation and fauna. It covers seven ancient bogs, zix slow- flowing rivers, five shallow lakes and over 30 springs. Pärnumaa means sun, sean and holidays. Pärnu is the summer capital of Estonia. It is rich in sandy beaches, forests, bogs and marshes. It is in the South-West of Estonia. Its area is about 32 square kilometres

predominated. The impact of centuries of dense human population has massively altered the flora of Britain and only small parts of those forests remain today. Although about 10 percent of Britain is still forested, most of this area consists of commercially planted coniferous forests in Wales. Before they were affected by the people, the oak forests spread over the best soils of Britain. Forests were unable to establish themselves in the poorer soils of the mountains, wetlands and heath. The plants common to these wilder areas are heather, peat moss, rowan and bilberry. Some wetland areas have drained and are now covered by towns and farmland. Animal life An estimated 30,000 animal species live in Britain, although many of them are on the endangered list. Britain has many small mammals and the large ones tend to be gentle. The only surviving large mammals are red deer and roe deer. Semi wild ponies also inhabit the Shetland Islands
massively altered the flora of Britain and only tiny remains of these forests remain today. Although 10 per cent of Britain is still forested, most of this area consists of commercially planted, fast-growing forests in Wales and northeastern Scotland. Before they were affected by centuries of clearing and human use, the great oak forests spread over the best soils in Britain. Forests were unable to establish themselves in the poorer soils of the mountains, wetlands, heath, and moorlands. The plants common to these areas are heather, gorse (astelhernes), peat moss (sammal), rowan (pihlakas) and bilberry (mustikas). These regions have been altered by heavy grazing of livestock and by controlled burning. Some wetland areas have been subjected to massive draining efforts for hundreds of years and are now covered by towns and farmland. 8. Agriculture, natural resources The open fields with their tiny strips of land worked by farmers were quickly replaced
The best place to see marshes is in the Soomaa National Park in Western Estonia. Soomaa indeed means "Bogland" in Estonian and impressive bogs cover the majority of the park with the thickness of the peat layer reaching up to 7 metres in some places. At least 10 per cent of the Estonian territory is subject to the environment protection. The most important protection areas are resting and recreation areas for migratory birds. Mainly seashore wetlands and chaste woodland and wetland areas. The preservation of traditional cultural landscapes is important as well. 5 History To the Nineteenth Century The Estonians settled in their present territory before the Christian era. They were mentioned by Tacitus 1st century A.D., who called them Aesti. In the 13th cent. the Danes and the German order of the Livonian Brothers of the Sword formed an alliance

above sea level. The relief of the present day lanscape was shaped suring the Ice Age. The hilly terrain was also shaped by the continental ice and melting waters. The land still rises 25 cm in every 100 years. Kalevipoeg, the national hero, is related to many features of the relief. The Baltic Glint is one of the world's most important denudations of Ordovician sedimetary rocks. Half of Estonia is covered with forests and 30 % is covered with wetlands. The areas which are higher and particularly rich in hills are the Haanja and Otepää Uplands in the southeastern part of Estonia. In Haanja Upland there is the highest top of Estonia, Big Egg Hill (318 m), which is the highest top of the Baltic states. There are over 1400 lakes in Estonia. Lake Peipsi, lying between Estonia and Russia, covers 3 555 sq km. It is the biggest in Estonia and the fourth biggest in Europe. The second largest lake is Lake Võrtsjärv (270 sq
A large interior basin centred on Hudson Bay and covering nearly four-fifths of the country is composed of the Canadian Shield, the interior plains, and the Great Lakes St. Lawrence lowlands. Canada's highest peak is Mount Logan (5,959 m) in Yukon Territory. 4. Rivers, lakes With less than 1 percent of the world's population, Canada has some one-seventh of the world's supply of accessible fresh water. Much of this water is stored in lakes and wetlands that cover about one-fifth of Canada's total area. The Great Lakes--the world's largest surface of fresh water--are shared with the United States and form part of the international border. Other large lakes include Great Bear and Great Slave lakes in the Northwest Territories and Lakes Manitoba and Winnipeg in Manitoba. Mackenzie River is Canada's longest river, which flows 4,241 km from its source to its mouth. With its many tributaries, it drains 1,800,000 square km. The St. Lawrence
of the world's most important denudations of Ordovician sedimentary rocks. The glint rises to its highest point (56m) at Ontika. Estonia has over 1,500 islands. The largest of them are Saaremaa, Hiiumaa, Muhu and Vormsi. There are over 1,400 lakes in Estonia, biggest being Lake Peipsi and Lake Võrtsjärv, while the deepest is Rõuge Suurjärv. The two longest rivers are the Võhandu and the Pärnu and the widest is Emajõgi. About 50% of the country is covered by forests while wetlands cover 30%. The landscape of Estonia, through covering a small area, is varied and unique. Lake Peipsi is Estonia's largest lake and Europe's fourth largest freshwater lake. 5. Symbols The flag The Estonian blue-black and white national flag was originally the flag of the Estonian Students' Society and was consecrated in Otepää Church in 1884. Today there is a memorial plaque on the church wall commemorating the event.

Mangrove trees have complex breathing roots above the surface of the organically rich and oxygen-depleted muds in which they live. Oil may block the openings of the air breathing roots of mangroves or interfere with the trees' salt balance, causing leaves to drop and the trees to die. The root systems can be damaged by fresh oil entering nearby animal burrows and the effect may persist for some time inhibiting recolonisation by mangrove seedlings. Protection of wetlands, by responding to an oil spill at sea, should be a high priority since physical removal of oil from a marsh or from within a mangrove forest is extremely difficult. Living coral grows on the calcified remains of dead coral colonies which form overhangs, crevices and other irregularities inhabited by a rich variety of fish and other animals. If the living coral is destroyed the reef itself may be subject to wave erosion. The effects of oil on
