The magnificent Daintree Rainforest

What a stunning place, lush greenery, exotic palms, fascinating butterflies and birds (we love the bush turkeys), pristine beaches, great weather... the list goes on. The area is the largest continuous tropical rainforest in Australia and classified as a World Heritage Site of great siginficance. The rainforest grows right down to the sea and the mangroves thriving in the silty shallows. 

A short ferry ride took us over the Daintree River and into the forest area, which is now quite habitated, with various accomodation choices available. We stayed in a caravan park, mixing it with so many different nationalities that few of our neighbours were able to speak English as a first language. We were right on the beach and a fun rope swing kept Amelia entertained for a while. Between swinging and searching for shells and virgin coconuts we were certainly occupied.

Crossing the Daintree River heading North-




The first beach (Cape Kimberley) we came to was almost deserted and perfect for exploring-

Driving further North we came across the Jindalba boardwalk, which runs through tropical lowland rainforest. Interesting facts on the rainforest include that up to 10 tonnes per hectare of leaves and branches fall each year from the canopy and this is quickly broken down into nutrients. This allows large trees to grow in poor soil. And boy do they grow tall! 


In the "basement" or root system live many other plants, animals and microorganisms- worms, fungi, tiny soil creatures. In the canopy live butterflies, spiders, orchids, ferns and many different bird species. 


Rainforest trees use many different ways to get to the light. Some grow slowly, some just wait til a tree falls and then grow super fast to make the most of the break in the canopy and others hitch a ride, starting at the top and sending their roots down to the forest flow. 

 


Jindalba is the Kuku Yalanji name for this area, which has been flourishing for more than 135 million years. It's all a bit of a miracle really given the conditions for growth being at times so challenging. Life in the wet tropics include challenges such as cyclones, high rainfall, intense sunlight (upper canopy), soils leached of nutrients and intense competition for light and food. As you can see many plants have developed clever ways of coping. 


The trees make their food using sunlight, nutrients and water. The canopy is an interlocking network of sun hungry trees, which is so efficient that less than 15% of sunlight actually reaches the forest floor. 



Rainforests are called closed ecosystems because their living parts; plants, animals and microorganisms are totally integrated. If this dynamic is destroyed by fire, erosion or clearing, nutrients are lost and not recycled. Extensively damaged rainforest may never return to its pristine state. But when conditions are right, rainforests are rapid colonisersm advancing around a metre annually. 



This amazing staghorn fern is dangling by the slightest of cords, can you see it in the middle of the photo?


Tropical rainforest needs at least 2 metres of rain a year to thrive. Much of this never reaches the forest floor, evaporating in the canopy or collecting in hollows. The rest drips off leaves or cascades down trunks, but the leaves need lots of water (along with soil nutrients) to make sugar. During summer, when sunlight is intense, evaporation is high and soils are saturated, a giant rainforest tree can pump hundreds of litres of water from the soil into the canopy. 

 blurry but so cute!


Circular Palm Ferns, which grow to amazing heights.


The rainforest canopy is an enormous solar panel of hungry leaves. These tilt to the most sun catching angle throughout the day. The leaves themselves are sugar factories, chorophyll converts the sun's energy, splitting water and carbon dioxide to make glucose (sugar). This fuels the plant and is the building block of cellulose from which the trunks, branches, leaves, fruits and flowers are built. In this rainforest area, a few large trees take up 80% of the sunlight. The surrounding undergrowth is reasonably clear as few plants can survive in such low light. 

Daintree Tea leaves farmed just up the road growing beautifully...



Right next to our tent is the short walk down to the the you know what!





 Another swing was required before breakfast




Had to include some photos of these impressive creatures scratching around the campground...
They cleaned out coconuts in record time and had a dominant bird which became possesive of the food source and proceeded to scare away any other birds which dared to sample the fresh coconut.

These sratch around in the leaf litter for materials with which to build their nests and for food; fruits, seeds, insects and snails. Using their strong legs they rake decaying matter into piles and lay their eggs within, where the heat from the matter decaying and microorganisms slowly rot the vegetation and the heat generated incubates the eggs. The scrubfowl carefully check the temperature of the mound and remove or add material to maintain a 30-35 degree temperature. 




And the artists impression of the bush turkeys/ scrub fowl...
