Adaptation Of Vegetation To Tropical Climate
• Tropical rainforests have a high biodiversity which is a response to climate
• There are five distinct layers in a tropical forest: emergent trees, canopy, under canopy, shrub layer, herb layer.
Adaptation Of Vegetation To Tropical Climate
• Tropical rainforests are evergreen, and consist of deciduous trees which shed their leaves at different times.
• The plants compete with one another for heat, light, moisture and nutrients.
• Tropical soils are called latosols; they are largely infertile, and most nutrients are found at the top.

Tropical Rainforest Soils
The tropical rainforest is often in the news for various reasons. There are major concerns about deforestation of it and the consequent damage to the soil. From a soil point of view, cutting down of the rainforest disturbs the natural soil-plant cycle and makes the soils extremely vulnerable to soil erosion and loss of this vital topsoil.
Tropical Rainforest Soils
The topsoil also holds huge amounts of carbon which is now known to have a major potential influence on CO2 levels in the atmosphere and hence a major potential influence on climate change.
WHY ARE RAINFORESTS IMPORTANT?
• THEY PROVIDE A HABITAT FOR PLANTS AND ANIMALS
• THEY REGULATE OUR CLIMATE
• THEY HELP TO PREVENT SOIL EROSION
• THEY PROVIDE A HOME FOR INDIGENOUS PEOPLE
• RAINFOREST PHARMACY

WHY ARE THEY BEING DESTROYED?
• CATTLE RANCHING
• LOGGING
• AGRICULTURE
• MINING
• OIL COMPANIES
• DAMS

Effects of deforestation
• Soil erosion destruction.
• Water Cycle
• Loss of Biodiversity
• Climate Change

Solutions to Deforestation
• Corporations & Markets
• Sustainable consumer options
• Politics

What You Can Do?
Wield your consumer power!• Make sure that the forest derived products you buy are made from
100% post-consumer content materials• Buy only from companies that have a commitment to reducing
deforestation through an environmentally friendly purchasing policy• If you are buying products made from virgin forest fiber, make sure
that it bears a seal from a credible forestry certification system, like the Forest Stewardship Council (FSC) Read more about the FSC and false forms of forest certification
• As a consumer ask questions about how the products you buy impact the forests.
• Educate your friends, family, and community about how our actions here can impact forests thousands of miles away.
• Visit this website to find many Case Studies
