  2. 2. Overview • Distributed near equator • Covers 2% of earth’s land surface • Comprises about 50% - 80% of total terrestrial species • Uniform warm temperature and high humidity • Heavy rainfall almost through out the year • Sunlight and nutrients are limiting factors 2
  3. 3. Global distribution 3
  4. 4. Location 4 Amazon and Orinoco Basins in South America and the Central American Isthmus Congo, Niger and Zambezi Basins of Central and Western Africa, and Madagascar; AND The Indo-Malay, Borneo and New Guinea Regions
  5. 5. Climatic conditions & Topography • Rainfall: 200cm to 225cm a year round • Temperature: ranges between 20 and 29 degrees Celsius ( 68 and 84 degrees Fahrenheit) • High humidity • Soil: exceedingly thick, acidic and low in nutrient content 5
  6. 6. Vegetation Highly stratified with trees forming mainly 5 layers: 1)Scattered, 50-60m tall emergent trees having shallow roots and buttresses 2)Canopy layer of 25-35m tall tree 3)Lower tree understory of 15-24m high trees developing into canopy openings at banks of river and streams 6
  7. 7. Contd… 4) Poorly developed shrubs and young trees in deep shade 5) Little vegetation with broad leaves at ground level; Abundance of lianas, vines, ferns, tree ferns, epiphytes and others 7
  8. 8. Some vegetation found in Tropical Rain Forest Bougainvillea Rafflesia Curare Durian Kapok Tree Mangrove Forests Tualang Bamboo Strangler figs Jambu 8
  9. 9. Animals • Insects make up the largest group • Home to some of the most beautiful birds, Example - Over 300 different species of parrots alone mostly residing on or in the canopies of trees 9
