BIODIVERSITY UNDER THREAT
To begin to build up a case study on the Daintree Rainforest
To identify the key aspects of the region
To evaluate the biodiversity of the region
This is a CASSOWARY it’s my height - about 1.75 m tall!!!
It can ONLY be found in the Daintree forest
It is severely threatened close to wild extinction- only 500 left
Vital to ecosystem as scatters seeds of over 100 species of plants
Without this bird eating seeds and then dropping them further away seeds would not spread through large areas of forest
It is a protected species and since 1999 numbers have increased from 54 to 500 in wild!
The Daintree forest lies on the North East coast of Australia in the area called Queensland, it's a part of the larger area known as the wet tropics.
It runs parallel to the other Australian wonderland the Great Barrier Reef
The wet tropics are a world heritage site, covering an area of 900,000 hectares (1/2 size of Wales)
135 million years old- oldest in world
Has plants there older than human life on Earth
Home to greatest no. of plant/ animal species that are rare, threatened anywhere in world
Of world’s 19 primitive plants 12 are found here
Deciduous tress, but look evergreen, as year round growing season means trees shed leaves at different times
1% of sun reaches floor- shrubs etc adapt to lack of light
About 200 species of tree in an area size of football pitch
Soil has thick litter layer, as leaves continuously fall, but humus is thin due to rapid decomposition in humid conditions
Nutrients are rapidly leached (drawn down into and lost in soil)
Reddish in colour due to high concentration of iron and aluminium
Has Australia’s largest range of ferns
Highest no. of ENDEMIC mammals anywhere in Australia
Has near ½ Australia’s bird species- 13 ENDEMIC
¼ of Australia’s frogs- 20+ of which are ENDEMIC
Greater diversity of freshwater fish in Australia
Has 65% of Australia’s butterfly and bat species
28 of 36 mangrove species
Timber, food, medicines, commodities like rubber, pets, clothing, fruit, species
Climate regulation, intake of Carbon, prevention of soil erosion, waste treatment, protection of water quality
Ecotourism, local cultures, traditional lifestyles
Level of photosynthesis, water cycle impacts, nutrient cycling
Provisioning- things that can be obtained-
Regulating- benefits obtained by regulating the ecosystem-
Cultural- non material benefits
Supporting- necessary for all other services provided
Carbon Sequestration- Daintree plants and trees store carbon in leaves which reduces pollution and regulates climate
Medicine- 25% of drugs are from rainforests, including chemicals to treat diabetes, heart disease, malaria, arthritis and traditional headache tablets. Many Daintree plants are identified as containing cancer fighting properties
People of the rainforest- rainforest aborigine people are the original owners of the forest- the natural rainforest and its processes are integral to these people and the way they live
Tourism- ½ million tourist visits a year from home and abroad, come for scenery- unique combo of forest, coast and mountains and the GBR all together- nowhere else like this on Earth
Logging- began in 1930s in the 80s arguments ensued between conservationists and timber industry- decided continued logging at then rate UNSUSTAINABLE.
