  • case study TRF
    • climate- temp varies form 20- 28 degrees. annual rainfall is 2104mm - highest in march 320mm and lowest in nov 5mm
      • trees are evergreen, vegetation is dense and light - lots of epiphytes and nutrients taken in. the trf has 4 layers emergent (buttress roots) support trunks and crowns (most light). the undercanopy as large leaves
      • animals- gorrliars, jaguards , insects birds
    • water cycle
      • 1. water evaporates from water bodies and tunrs into water vapor by transpiration  2. water vapour is moved by winds and   cools/ condense to form  clouds    3. rains - water stored in land and is evaporated again- cycle
        • the soli is very thin and fertile and poor nutrients- if trees are removed it means rain directly hits grount too much rain causes nutrients to wash away -leaching
    • nutrient cycle
      • 1. plants absorb nutrient from soil and grow. animals eat plants taking in nutrients     3. plants drop leaves and animals return nutrents to soil as they die  - cycle
    • good and services
      • good --high biodiversity means more sources e.g medicine , coffee , hardwoods
      • services - high diversity means rain forests help regulate water cycle, reduce climate change, reduce risk of flooding
    • human activities
      • logging- removal of trees interrupts the water cycle  rain washes away soil - eroded soil goes into rivers-infertile, it also increases amount of co2  however logging allows development of new roads /buildings
      • agriculture- burning vegetation produces co2- green house effect- large cattle farmers cause more damage- artificial fertilizes are washed into rivers
      • mineral extraction-  uses toxic chemicals to extract and purify metals- washed away into river killing wildlife- polluting water- removal of trees due to heavy machiens
      • tourism -trampling- littler- damage vegetation- littler
    • yachana lodge
      • ecotourism is tourism that minimizes damage to the environment and benefits local people
      • impact
        • people- loss of traditional ways of life as local mix with tourist - more job opportunities mean fewer young are migrating
        • environment- tourists visit in small groups so that harm to environment is minimized and take part in activities to raise awareness of conservation issues
        • economy- tourists have to pay for entrance fees - this brings more money for rainforest conservation- profits invested in educational projects to promote conservation in local community-
