  16. 16. Tropicalrainforests
  17. 17. Why are they called TROPICAL rainforests?
  18. 18. Tropic of Cancer and Tropic ofCapricorn Equator They are located within the Tropic of Cancer and the Tropic of Capricorn
  19. 19. How many seasons are there?
  20. 20. Some regions have only one: the WET Some regions have two: the WET andseason the DRY seasonWET & DRY SEASONS
  21. 21. What is the average temperature?
  22. 22. The temperature during the day is around 30ºC - 35ºC. At night it drops to between 20ºC - 25ºC. There is a little difference between the warmest and the coolest months.Average temperature
  23. 23. What is the average rainfall?
  24. 24. The total rainfall forthe year is between1500 and 2500 mm.
  25. 25. What is the total earth landsurface which rainforests cover?
  26. 26. Rain forests cover less than 6% of the earths total land surface
  27. 27. What is the soil like?
  28. 28. The rainforest soil Shallow and acidic Iron oxides stain the top layers red Infertile One of the poorest in the world Rainfall washes away nutrients Plant and animal remains provide nutrients to vegetation
  29. 29. Rainforests are home for up to½ (50%) or¾ (75%)of all known species of plants?
  30. 30. ¾ (75%)
  31. 31. Why are there so many species?
  32. 32. Rainforests are very old, some almost 100 million years old. About 10,000 years ago the ice caps at the poles spread out in an Ice Age, but the ice didnt reach the Equator so tropical rainforests survived and their plant and animal species continued to evolve when other places on earth had to start growing plants all over again.http://www.kidcyber.com.au/topics/biomerainfor3.htm
  33. 33. How many of the world’s animalspecies are found in rainforests?
  34. 34. Almost half of the world’s animal speciesare found in rainforests. 30 million species of plants and animals live there http://www.ladatco.com/rf-qf.htm#Some Quick Facts
  35. 35. HOW MANY BIRDS?
  36. 36. 1/3 OF ALLIN RAINFORESTSWORLD LIVE THE BIRDS IN THE
  37. 37. How many levels do rain forests have?
  38. 38. Three to four different levels:
  39. 39. DescribeTHE EMERGENT LAYER
  40. 40. The emergent layer… Tallest trees Up to 60 metres Trunks measure up to 5 metres Supported by buttress roots Broad leaves with thick waxy layers to hold water Eagles, monkeys, butterflies, insect- eating bats and snakes
  41. 41. DescribeTHE CANOPY LAYER
  42. 42. The canopy layer  Beneath the emergents  Up to 45 metres  Smooth, oval leaves that come to a point (shed rain quickly). They have reflective propertly  Filters out 80% of light  Stops rain  Monkeys, sloths, bats, treefrogs, ants, beetles, parrots, hummingbirds and snakes  Thick, woody vines (lianas)  Epiphytes grow on the trees: orchids, ferns, mosses, lichens and others.
  43. 43. DescribeTHE UNDERSTOREYLAYER
  44. 44. The understorey layer Gets limited sunlight Trees: Solar-collecting dark green leaves: dwarf palms, acanthus, prayer plant, etc. Plants rely on insects for pollination plants have had to adapt to poor soil with few nutrients: anthurium, caladium, colocasia, philodendron and garden callas Many animals live here: snakes, frogs, parakeets, leopards, jaguars and the largest concentration of insects.
  45. 45. DescribeTHE FOREST FLOOR
  46. 46. The forest floor  Almost no plants grow of 0% light and 100% humidity  Mosses, herbs and fungi grow here.  covered with a litter of rapidly decomposing vegetation and organisms that break down into usable nutrients  Large mammals, such as tapirs, forage for roots and tubers.  Insects: termites, cockroaches, beetles, centipedes, millipedes, scorpions and earthworms, along with the fungi, use the organic litter as a source of food.
  47. 47. Why are rainforests importantto us?
  48. 48. IMPORTANT TO PLANTS, ANIMALSAND MANKIND… One-fifth of the worlds fresh water is in the Amazon Basin.
  49. 49. Important to plants, animals and mankind…Plants contain substances thatcan be made into MEDICINES
  50. 50. IMPORTANT TO PLANTS, ANIMALSAND MANKIND…Rainforests store huge quantities of carbon, producing much of the world’sOXYGEN
  51. 51. Rainforests REGULATE GLOBAL WEATHERMaintain regular rainfallPrevent FLOODS,DROUGHTS, EROSION
  52. 52. · A single pond in Brazil can contain One tree in Peru had forty-threemore kinds of fish than are found in all different species of ants, which is theof Europes rivers. estimated to be equal to the number of ant species in the British Isles. 30% of all bird species and 90% of all invertebrates are found in the tropical forest.
  53. 53. Human Impact…
  54. 54. WHAT IS DESTROYINGTHE RAINFOREST?
  55. 55. In the Amazon rainforest In the South east Asia rainforest DEFORESTATION
  56. 56. Deforestation in the world
  57. 57. Nearly half of theworlds species ofplants, animals andmicrooganisms willbe destroyed orseverely threatenedover the nextquarter century dueto Rainforestdeforestation.
  58. 58. Cattle grazing Amazon rainforest covers 1,2 billion acres - 200,000 of them are burned every day at a rate of al least one per second.
  59. 59. GLOBAL WARMINGIn 2005, the Amazon forest suffered its worst drought inover 100 years raising serious environmental issues.
