Rainforest

  1. 1. Tropical Rainforests
  2. 2. Tropical rainforests <ul><li>Tropical (or equatorial) rainforests occur near the equator </li></ul><ul><li>This provides a hot and wet climate for the majority of the year </li></ul><ul><li>However rainforests do occur in other places </li></ul><ul><ul><li>NZ has temperate rainforests </li></ul></ul>
  3. 3. Spatial variation <ul><li>Is there a spatial variation of rainforests? </li></ul><ul><li>If so what is it and what is the relationship? </li></ul><ul><li>Explain with a sentence in your book </li></ul>
  4. 4. Rainforests <ul><li>Rainforests can develop anywhere that receives enough rainfall </li></ul><ul><ul><li>New Zealand has temperate rainforests because of it’s cooler climate </li></ul></ul>
  5. 5. Community <ul><li>A rainforest is a community of plants and animals </li></ul><ul><li>Shrubs, herbs, trees, mosses, ferns, insects and animals all live together </li></ul>
  6. 6. Vegetation Stratification <ul><li>The plant life in the rainforest is made up of four distinct layers </li></ul><ul><ul><li>Using this diagram as guide construct a vegetation stratification diagram using the text in the following slides </li></ul></ul><ul><ul><li>Do this as a draft first, then you will have time to complete it into your book after we have covered all the forest layers </li></ul></ul><ul><ul><li>Use a full page to do this </li></ul></ul><ul><ul><li>Use annotations form the text you see </li></ul></ul>
  7. 7. Emergents <ul><li>The highest trees in the rainforest tower 30 - 50m above the forest floor </li></ul><ul><li>They are called emergents because they emerge from the forest canopy </li></ul><ul><ul><li>These trees have huge crowns that spread high and wide above the forest </li></ul></ul><ul><ul><li>Flowers and fruit grow in the crowns </li></ul></ul><ul><ul><li>Apes, parrots and other birds use the trees for food </li></ul></ul>
  8. 8. Canopy <ul><li>The main canopy is formed by a tangle of branches of many trees </li></ul><ul><ul><li>This forms continuous cover </li></ul></ul><ul><ul><ul><li>Like an umbrella blocking sun, rain and wind </li></ul></ul></ul><ul><ul><ul><li>This means there is a fight for sunlight for the plant life underneath the canopy </li></ul></ul></ul><ul><li>Can be 20 – 30m above the forest floor </li></ul><ul><li>You can see in the diagram that the canopy is made up of trees and tangles of vines </li></ul>
  9. 9. Understory <ul><li>This is a layer of younger trees and smaller species of tree and shrubs </li></ul><ul><li>These plants sometimes have large leaves and brilliant coloured flowers </li></ul><ul><li>The least dense layer in </li></ul><ul><li>the forest </li></ul><ul><li>There are many epiphytes </li></ul><ul><ul><li>Plants that grow on trees </li></ul></ul><ul><ul><li>and use them for support </li></ul></ul><ul><ul><li>but not nourishment </li></ul></ul><ul><li>Many animals live here </li></ul><ul><ul><li>Tree climbing frogs, </li></ul></ul><ul><ul><li>geckos, flying-snakes etc </li></ul></ul>
  10. 10. Forest Floor <ul><li>Also known as the immature and herb layer </li></ul><ul><li>Hot, still and humid </li></ul><ul><li>Shade tolerant plants such as mosses and ferns </li></ul><ul><li>Dead and rotting vegetation that falls to the floor supports a wide variety of small insects, animals, bacteria and fungi </li></ul><ul><li>Can support large animals such as tigers, elephants, leopards and wild pigs </li></ul><ul><li>In African and South American Rainforests there are few </li></ul><ul><li>ground animals </li></ul>
