- 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
- 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
- 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-
- climate- temp varies form 20- 28 degrees. annual rainfall is 2104mm - highest in march 320mm and lowest in nov 5mm
