  • The Daintree rainforest
    • The Wet Tropics
      • The Daintree rainforest is in northern Queensland, Australia.
        • It's part of a huge stretch of rainforest, the Wet Tropics which runs parallel to the Queensland Coast. This coast runs alongside the Great Barrier Reef.
      • Highest level of biodiversity and regional endemism in Australia. Covers almost 900 000 hectares (nearly 1/2 size of Wales)
        • Adjacent to the GBF- 400 types of coral, 1500 species of fish.
    • Why is the Daintree rainforest so special?
      • Of 19 primitive plant families on Earth, 12 are found here
        • E.g. the idiot fruit is found only in the Daintree.
      • Has almost 1/2 of Australia's bird species, and 13 species found nowhere else in the world.
        • E.g. the Cassowary is a large bird- unlikely to meet a southern Cassowary unless you go to the tropical ranforests of north-east Queensland.
          • In 1993,there were 54- birds left in the Daintree rainforest but, since ty became protected in 1999, their numbers have increased- estimated 500 in 2009.
            • The Cssowary is vital to the rainforest ecosystem.
              • 'Seed dispenser' for100+ species of rainforest plants with large fruits. Without thenm, new plants would concentrate around the parent plant and would not spread throughout the rainforest.
      • Has 65%+ of AU's butterfly and bat species.
        • E.g. the Ulysses butterfly- icon of tropical northern AU's.
      • Has 28 of AU's 36 mangrove species.
    • Is 135m years old.
      • Takes up less than 0.2% of the landmass of AU.
    • The tropical rainforest ecosystem:
      • Climate (found in places with an equatorial climate).
        • A low daily range of temp. Rarely drop below 22oC at night, or go above 32oC in the day.
          • Low annual temp. range.
        • High annual rainfall (2000+mm) in intense convectional storms.
          • Daintree has 120 days of rain per year.
        • Year-round growing season.
      • Vegetation
        • The trees are deciduous, but the rainforest looks evergreen as the year-round growing season means they can shed their leaves at any time.
        • As many as 200 species of tree per hectare (rugby pitch).
        • Rainforests are the most productive terrestrial ecosystem.
        • Mangroves fringe the coast of the Daintree.
      • Soils
        • Rapid leaching of ntrients.
        • Bedrock is intensely weathered due to the hot, wet, conditions.
    • Ecosystem servies
      • Carbon sequestration
        • Trees absorb CO2 and give out O2, removing GHG'S from the air. Helps reduce pollution and regulate climate change.
      • People of the rainforest
        • The natural features of the rainforest are interwoven with the people's religion spirituality, economic use (food, medicine, tools) and social + moral organisation.
      • Medicine (last mind map)
      • Logging + deforestation
        • Commercial timber industry began in Daintree in 1930's. 1980's- centre of arguments between conservationists + timber industry.
        • Queensland- most land clearance is now undertaken for pasture (86%),crops (10%), mining, infrastructure + settlement (4%). Shiften from Central to Southern Q.
      • Tourism- the most dangerous threat.
        • Daintree attracts nearly 1/2 a m a year
        • In 2002, tourism + recreation was worth A$141.7m a year; creating 3500 jobs.
        • 1983=17 000 visited the Daintree 436 000 a year in 2002.
        • 1999, 37% of visitors thought there was a need for more walking tracks in Daintree. 40% in 2001.
    • Development-  growth + change in Port Douglas
      • Its pop. is only 4000 but a rise in the num. of visitors has:
        • A large supermarket was built in the centre of the village in 1999: Local shops deteriorated.
        • A property boom led to  rising house prices. Some benefited from selling their land to developers. Others found it difficult to buy a house
        • 2008, 5 new resorts were built/ planned.
      • In Daintree, there were 550 residents (2002).
        • Tarmacking opened up the region.
          • Most turned to cattle ranching. E.g. red cedar family of trees became extinct in 2000  when a landowner cleared a  plot of land.
            • If deforestation is not reduced, 85 rare plant species now on private land will become extinct.
          • Areas of forest divided into 1000+ plots for sale.
