    • What are Rainforests?
      1
    • Rainforests are characterized by
      2
      • Very high rainfall amounts
      • Normally between 68-78 inches
    • Did you know?
      3
    • There are two types
      4
      Tropical
    • And ….
      5
      Temperate
    • Tropical Rainforests are found in the tropics near the equator.
      6
    • Temperate Rainforests are found in temperate regions between the tropics and polar circles.
      7
    • Did you know?
      8
    • That 45-70% of Earth’s species are unique to rainforests.
      9
    • And millions of plants, insects and microorganisms are still undiscovered
      10
    • Did you know?
      11
    • Rainforests are responsible for 28% of Earth’s oxygen turnover (process)
      12
    • Did you know?
      13
    • Rainforests have 4 main layers. Each layer
      has different plants and animals
      adapted for life in that area.
      14
    • The Emergent Layer contains a small
      number of very large trees, called emergents. These trees must withstand
      hot temperatures and strong winds.
      15
    • Eagles, butterflies, bats and monkeys live here.
      16
    • The Canopy Layer contains the majority
      of the large trees. The canopy is home
      to 50% of all plant species.
      17
    • The fauna in this layer is similar to that in the emergent layer but more diverse.
      A 1/4 of all insect species are believed
      to exsist in the canopy.
      18
    • The Understory Layer or the shrub layer lies between the canopy and the forest floor.
      Only 5% of sunlight shining on the
      rainforest reaches the understory.
      19
    • The leaves in this level are much larger making a great home for insects. This layer is also home to birds, snakes, lizards, jaguars, boa constrictors and leopards to name a few.
      20
    • The Forest Floor Layer is the bottom layer of the rainforest. There is little vegetation here because it receives only 2% sunlight.
      21
    • Did you know?
      22
    • More than half of the world’s species of plants and animals are in the rainforest.
      23
    • Rainforests support various types of species including mammals, reptiles, birds, invertebrates. Fungi is also very common.
      24
    • Did you know?
      25
    • We use the Rainforest for
      Timber
      Animal products (meat, hides)
      Tourism destinations
      Food
      Medicines
      (¼ of medicines have been discovered here)
      26
    • But….Did you know?
      27
    • We affect the Rainforest
      Human induced deforestation plays a significant role in the future of the rainforest. Due to the heavy logging the rainforests are shrinking.
      28
    • This causes many species to be driven to extinction. Biologists estimate extinction is happening at a rate of 50,000/ year.
      29
    • Did you know?
      30
    • You can help save the Rainforest
      Recycle everything you can!
      Use cold water when possible!
      Reuse grocery bags!
      Store things in reusable containers!
      Don’t leave water running!
      Put up birdfeeders!
      Watch out for wildlife!
