The mountains within each climate zone also support clearly defined vertically distributed belts of vegetation. Some forest types among the components of the vertical vegetation belts on some mountains can also be found within several climate zones. (1) Boreal Forests The boreal forests of China can be classified into 5 different forest types: 1) larch (Larix spp.) forests; 2) spruce (Picea spp.) forests; 3) fir (Abies spp.) forests; 4) pine (Pinus spp.) forests; and 5) Sabina spp. forests. These forests usually occupy cold, moist sites, usually on hills or on low to high mountains. Larch forests. There are 10 species and 2 varieties of Larix in China, or more than half of all species of Larix worldwide. Nine types of larch forests are dominated by different species of Larix. Larch, an important timber tree in China, is characterized as a pioneer species in burned or cleared areas, and by species with seeds capable of being dispersed over long distances, the germination capacity of which is strong. Larch plantations are being developed rapidly in China (Zhou, 1991). Pine forests. There are two types of pine forests in the cold temperate region of China, one with P. sylvestris var. mongolica, the other with P. pwnila. Forests of P. sylvestris var. mongolica occur in the northeastern part of China. The P. pumila forests are not extensive, occurring only in a narrow area along the top of the Great Xingan mountain range.

People and place - indigenous cultures and an extraordinarily rich forest and marine bioregion -developed together in the coastal temperate rain forests of North America in the millennia following the most recent Ice Age. The unusual diversity and abundance of fish, shellfish, wildlife, and forest resources that characterize this bioregion supported one of the densest populations of non-agricultural peoples known anywhere on earth. Native languages proliferated and distinct cultures arose up and down the coast partly in response to the local variations in resource abundance. The south-to-north sweep of the western industrial economy that followed settlement has diminished both indigenous cultural and ecological integrity. Languages, art, and an irreplaceable legacy of cultural knowledge of the environment have been lost as fast or faster than plant and animal species. Today both Native and non-Native coastal communities, and the ecosystems that sustain them, face new challenges. The rela-tionship between people and place, once synergistic, is now at risk.

Students and Teachers Over the years, scientists, foresters, and others have watched some forests grow more slowly without knowing why. The trees in these forests do not grow as quickly at a healthy pace. Leaves and needles turn brown and fall off when they should be green and healthy. In extreme cases, individual trees or entire areas of the forest simply die off without an obvious reason. How Acid Rain Harms Trees Acid rain does not usually kill trees directly. Instead, it is more likely to weaken trees by damaging their leaves, limiting the nutrients available to them, or exposing them to toxic substances slowly released from the soil. Quite often, injury or death of trees is a result of these effects of acid rain in combination with one or more additional threats. Scientists know that acidic water dissolves the nutrients and helpful minerals in the soil and then washes them away before trees and other plants can use them to grow. At the same time, acid rain causes the release of substances that are toxic to trees and plants, such as aluminum, into the soil. Scientists believe that this combination of loss of soil nutrients and increase of toxic aluminum may be one way that acid rain harms trees. Such substances also wash away in the runoff and are carried into streams, rivers, and lakes. More of these substances are released from the soil when the rainfall is more acidic.

These forests are found next to oceans, where evaporation fills the air with water vapor. As the ocean air sweeps over the land, the moisture comes down as rain. Rain forests are filled with plants of different heights. As the sunlight is filtered through the leaves, sometimes the air looks almost green! There are two kinds of rain forests: tropical and temperate. Tropical rainforests are found near the equator. They have very rich ecosystems, with many kinds of plants and animals living together. Temperate rainforests are cooler, and have fewer species living in them. They provide ideal conditions for conifers, mosses, ferns, and fungi.

Extractions: T. Sibona. F.A.O Plants Animals Climate Southeast Asian Rainforests The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly. Rainforests now cover less than 6% of Earth's land surface. Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earth's oxygen. A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees. About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, and is used as an anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. All tropical rain forests resemble one another in some ways. Many of the trees have straight trunks that don't branch out for 100 feet or more. There is no sense in growing branches below the canopy where there is little light. The majority of the trees have smooth, thin bark because there is no need to protect the them from water loss and freezing temperatures. It also makes it difficult for

Extractions: Back to Spotlight Humans already have destroyed half of this forest area, with most damage occurring in the last 200 years. With just 2.5 million square miles (647 million hectares) of tropical rain forest remaining, we continue to lose an estimated 93,000 square miles (150,000 square km) a year. It is not only quantity of life, but diversity as well, that makes rain forests so vital. Some of the strangest and most beautiful plants and animals are found in rain forests, and undoubtedly there are just as many we do not even know about. Rain forests are being eliminated for timber, minerals, agriculture, and human settlement. Other motives, such as the desire to conquer nature or to control unoccupied territory, also are factors in deforestation. Overpopulation and peasant agriculture is often cited as the cause of deforestation. This may be true of some African and Asian countries, but generally countries with the most tropical rain forest are those with the lowest human population densities. It is not population pressure but the inequitable distribution of land ownership that creates the most pressure on tropical forests. In many developing countries the government and a very small percentage of people own the majority of the land. Logging, mining, and other industrial activities are not driven primarily by local population pressures. Industrial development and settlement often go hand in hand because roads give access to cleared land. Most attempts to turn tropical forest into farmland have failed, resulting in damaged soil and disrupted water systems, leaving settlers even more desperate for land.

Conclusion Introduction Welcome to the world of the tropical rainforest, teeming with rare species of animals and plants that exist nowhere else on earth. Located between the Tropics of Cancer and Capricorn, rainforests are characterized by hot, humid weather all year long, which creates an environment conducive to an abundance of growth. Hundreds of years ago, tropical rainforests encircled the globe, much like long green arms, hugging the equator and covering 20% of the earth's land surface. Reduced to a mere 6%, the diminishing rainforest shelters more than half of all the plant and animal species living in the world today. Rapid deforestation has endangered the splendor of this tropical paradise.

Extractions: TrackBack Print E-mail TalkBack The rain forests of South America are holding onto carbon dioxide for a lot less time than previously believed, which raises implications for how to deal with global warming, according to a new study. Most of the carbon dioxide being "exhaled" or released by wetlands and rivers has spent around five years sequestered in trees, according to a new study performed by researchers from the University of Washington, Rice University and the Stroud Water Research Center. The tropical forests in the 2.4 million square miles of the Amazon river basin gulp in carbon dioxide during photosynthesis. Scientists have long believed that most of the carbon dioxide ingested by the forest stays there until the trees decompose decades later. Carbon found in water samples have been shown to be 40 to 1,000 years old, according to Emilio Mayorga of the University of Washington. Because carbon dioxide is a greenhouse gas that can trap solar energy, many scientists postulated that the rain forests could help curb the impact of

This ecosystem stretches along the Pacific Coast from Oregon to Alaska; other temperate rain forests are found in several isolated areas throughout the world. What defines a rain forest quite simply is rain lots of it. Precipitation here ranges from 140 to 167 inches12 to 14 feetevery year. The mountains to the east also protect the coastal areas from severe weather extremes. Seldom does the temperature drop below freezing in the rain forest and summertime highs rarely exceed 80 F. The dominant species in the rain forest are Sitka spruce and western hemlock; some grow to tremendous size, reaching 300 feet in height and 23 feet in circumference. Douglas-fir, western redcedar, bigleaf maple, red alder, vine maple, and black cottonwood are also found throughout the forest. Nearly every bit of space is taken up with a living plant. Some plants even live on others. These are the epiphytes, plants that do not come into contact with the earth, but also are not parasites. They are partly responsible for giving the rain forest its "jungly" appearance. Mosses , lichens and ferns cover just about anything else. Oregon oxalis is also a common ground cover. But because of this dense ground cover it is hard for seedlings to get a start. Many seedlings germinate on fallen, decaying trees. As they grow they send their roots down the log to the ground. Eventually the log rots completely away and a row of young trees is left, up on stilt-like roots, all in a row. The thick and protective vegetation also provides excellent habitats for the animals of the rain forest. In turn, they contribute to the health of the forest by keeping the rampant vegetation under control by browsing.

Extractions: Rain Forests The rain forest is the liveliest ecosystem on earth! Trees here have leaves so densely packed that they look like a large, green blanket in mid-air. Sunlight can hardly penetrate through this natural "green blanket", making the ground very shady. Weather here is hot and humid all year round - the average temperature is 77 degrees Fahrenheit, and the average monthly rainfall is 4 inches. Warm climate and plentiful rains create a perfect environment for plants and animals to thrive. At least 50% of all the plant and animal species in the world are in the rain forest. So, where can we find rain forests? Rain forests are near the Equator. Regions in Asia, Africa, Australia, Central America, and South America all have the Equator nearby. Thus, we can find rain forests there. The Amazon of South America is the world's largest rain forest, and it covers an area of more than 1.5 million square miles. In fact, the Amazon is so large that its size is about half of the combined coverage of all the rain forests.
