Tropical Rainforest

Extracts from this document...


Structure of vegetation in the rainforest Emergent's are the tallest trees and are usually over 50 meters tall. The sea of leaves blocking out the sun from the lower layers is called the canopy. The under canopy mainly contains bare tree trunks. The shrub layer has the densest plant growth. It contains shrubs and ferns and other plants needing less light. The forest floor is usually dark and damp. It contains a layer of rotting leaves and dead animals. Impacts on indigenous people � The replacement of forest with grassland can also have a major effect on the way of life of indigenous people. Without the forest wood, they cannot make the artifacts, tools, and buildings that are an important part of their economy � Deforestation in indigenous territories by loggers has sometimes triggered violent conflict. Logging, mining, and farming in tropical forests sometimes displace native communities. Left without land or other resources, native cultures often break up. ...read more.


� One of the major problems of the scheme has been establishing the trust and cooperation of local villagers. For many, hunting is part of tradition and a main source of income, yet now carrying a firearm without a permit is illegal and hunting is discouraged. In general, tropical rainforests have hot and humid climates, where it rains virtually everyday. At some parts of the year the rainfall is extremely heavy, while in other parts of the year it will rain a lot less. Temperatures vary through the year - but much less than the rainfall. ropical rainforests have dense vegetation, which typically occurs in four levels. From ground level up these levels of vegetation are: * The shrub layer is at ground level in a tropical forest. It is dark and gloomy with very little vegetation between the trees. During heavier rainfalls this area can get flooded. * Under canopy is the second level up. ...read more.


However shallow roots aren't great for supporting huge rainforest trees, so many tropical trees have developed huge buttress roots. These stretch from the ground to two meters or more up the trunk, which help anchor the tree to the ground. 3. Lianas are woody vines that start at ground level, and use trees to climb up the canopy where they will spread from tree to tree to get as much light as possible. 4. Strangler figs start at the top and work down. The seed is dropped in a nook at the top of a tree where it starts to grow, using the debris collected there. Gradually the fig sends aerial roots down the trunk of the host, until they reach the ground and take root. As it matures, the fig will gradually surround the host, the aerial roots will criss-cross the trunk and start to strangle. Meanwhile the figs branches will grow taller, dominating the sunlight, while invasive roots rob the host of nutrients. Eventually the host will die and decompose leaving the hollow, but sturdy trunk of the strangler fig. ...read more.

  2. Destruction of Amazonian Rainforest and its effect on the environment

    The lack of security of forest ownership and forest-use rights encourages exploitative behaviour. Some policies even require deforestation in order to show the owner has "improved" the land. Commercial and official debt, owed by many developing nations to industrialized countries, forces developing countries into deforestation to generate foreign exchange.

  1. Destruction of tropical rainforests

    This problem can result in desertification; which is when without trees there will be less evapotranspiration, therefore, a decrease of water vapour in the air. This will reduce rainfall totals and, according to experts, will increase the possibility of tropical rainforests like the Amazon being turned into a desert.

  2. The Tropical Rainforest

    There are two cycles in the tropical rainforest, a nutrient cycle, where the leaves fall and hit the ground to be fed on by the decomposers, and a water cycle, where the rain falls, some of it collecting in the leaves and some of it making it's way down to the forests floor, and rivers, 80% of it is recycled.
