forests or pine forests with birches as scattered associates. Puistud on üsna hõredad (täius on 0,6), need koosnevad ainult männikutest või männikutest vähese kase seguga. The productivity is low, the quality classes are IV to V. Tootlikkus on madal, boniteediklass on IV...Va. The undergrowth is either absent or consists ob sparse junipers. Alusmets kas puudub või koosneb hõredalt paiknevatest kadakatest. The ground vegetation includes heather, coeberry, bilberry, crowberry, common cow-wheat, Lerchenfeldia flexuosa. Alustaimestik sisaldab kanarbikku, pohla, mustikat, kukemarja, palu-härgheina, võnkvart. In the moss layer the dominant species are Pleurozium schreberi and Dicranum. Samblarindes on domineerivaks liigid palusammal ja kaksikhambad. MESOTROPHIC (PINE) FORESTS - PALUMETSAD The mesotrophic (pine) forests grow on soils of average to high fertility which have
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. Once wild boars and wolves roamed Britain but they were hunted to extinction.
The sunflower (Helianthus annuus) is an annual(iga aastane) plant in the family Asteraceae, with a large flower head (inflorescence(õiekobar, õisik, õitseaeg, õidumine)). The stem(tüvi) of the flower can grow up to 3 metres tall, with the flower head reaching 30 cm in diameter. The term "sunflower" is also used to refer(nimetama, viitama, üle andma) to all plants of the genus(perekond, sugu) Helianthus, many of which are perennial(alaline, aastaringne) plants. What is usually called the flower is actually a head (formally(ametlikult) composite(liit-, komposiit- ; korvõieline, komposiit) flower) of numerous flowers (florets) crowded(täistuubitud, tunglev, rahvarohke) together. The outer flowers are the ray florets(pähik (õisiku osa) and can be yellow, maroon, orange, or other colors, and are sterile(steriilne, viljatu). The florets inside the circular head are called disc florets. Sunflower head displaying florets in spirals of 34 and 55 around the outside The florets wi
Temperate deciduous forests, woodlands and shrub Tartu 2008 Location: Temperate forests are typical of all European continent, the Eastern region of Asia (in special, Chinese and Japan) and North America. Also are finded in tempered areas of South America. Climate: The average temperature in temperate forests is 50° F. Summers are mild, and average about 70° F, while winter temperatures are often well blow freezing. The average yearly precipitation is 30-60 inches. This precipitation falls throughout the year, but in the winter it falls as snow. There are four seasons in this biome, with warm summers and cold winters, often snowy. In autumn, the leaves change color and fall from the trees. The leaves decay on the forest floor, so the soil is very rich. Because of this, and because of the long growing season, many deciduous forests have been cut down for farming purposes. Plants: Trees of this biome include hardwoods such as maple, oak, hickory, and beech. There

Temperate deciduous forest -Well-defined seasons with a distinct winter characterize this forest biome. Moderate climate and a growing season of 140-200 days during 4-6 frost-free months distinguish temperate forests. Temperature varies from -15° C to 25° C. Precipitation (750-1500 mm) is distributed evenly throughout the year. Temperate grassland- Semiarid, continental climates of the middle latitudes typically have between 25 cm and 50 cm of precipitation a year. Much of this falls as snow, serving as reservoir of moisture for the beginning of the growing season. Warm to hot summers are experienced, depending on latitude. In the winter, grassland temperatures can be as low as -40° C, and in the summer it can be as high 20° C. There are two real seasons: a growing season and a dor
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 by compact farms, with large farms surrounded by hedges and ditches to prevent stray

Different types of forests and their forms of usage TARTU 2010 Forest A forest (also called a wood, woodland, wold, weald, holt, 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 5
