1. Sustainable Logging

   • Sustainable logging is an environmentally safe way of cutting down trees
     • Sustainable logging is when one tree is cut down and new ones are replanted which means the ground stays fertile

2. Examples of the main tropical rainforests

   • Amazon
   • The Congo
   • Sinharaja
   • Daintree
   • Valdivian
   • Santa Elena
   • Kinabalu
   • Tongass

3. The layers of the rainforest

   • Names and height they are found at
     • Shrub Layer
       • Under 10m
     • Under Canopy
       • 10-20m
     • Canopy
       • 20-30m
     • Emergents
       • Over 30m

4. Deforestation

   • Deforestation is what is happening to rainforests all over the world right now
     • In places like the Amazon rainforest illegal logging is going on and the loggers are not being environmentally friendly while they are logging and are not making sure the trees that they cut down are sustainable

5. The 5 main ecosystems

   • Tropical Rainforest
     • A tall, dense forest found in hot, wet climates
   • Tundra
     • A vast, flat, treeless Arctic region of Europe, Asia, and North America in which the subsoil is permanently frozen
   • Hot Desert
     • A dry, often sandy region of little rainfall, extreme temperatures and sparse vegetation.
   • Savanna
     • A grassy plain in tropical and subtropical regions, with a few trees
   • Deciduous Forest
     • A type of forest characterised by trees that seasonally shed their leaves
