Try not to transport frewood too far from where you gather it please!
It can carry termites obviously - but also a host of other baddies like Fungal diseases, such as Phytophthera cinnamomi (Dieback) and end up spreading the spores, and wipe out heaps of previously uninfected trees.
These spores spread thru the ground when wet - they travel slowly but over a period will work their way down slope until the whole water catchement becomes infected as far as the ocean.
Many of our trees have zero resistance to Dieback (Banksias spring to mind) and will be dead within 12 months of becomming infected, while others like a big Jarrah might take up to 40 years to die.
If you shift the fungus, via moving infected wood from one catchement to another by driving up over a ridge or saddle between two catchements, you've effectively sentenced every suscepticble tree within that new ctahcement to death - whether it is 12 months 40 or 100 or more years before it eventually happens.
Humans activities are by far the biggest spreaders of dieback, wet mud stuck to mudflaps is the easiest method to spread it - hit a bump further down the road and it drops off with infected spores in it - you just killed another million trees.
Dieback is so named because the tree dies from the tips of the crown back toward the centre of the trees crown.
This happens because the trees roots sense the invading spores of P cinnamomi fungus trying to invade the root tissue. The trees only natural defence against such invasion is to close down that root and stop intake of nutrients and water, and as it does so - it starves the trees crown and leaves of the nutrients they need to survive so we see the dreaded dieback symptom in the crown where the leaves die and the branches twigs etc stick out past the leaves.
Then the spores move downslope thru the moist soil to the next root and it in turn closes down - over a period of time ALL the trees roots close down and it dies!
The spores get into the wood and travel thru the tree - you come along - see a dead / fallen tree or branch and cut it up for firewood - and transport it to Northern territory or Tasmania - whatever and the whole shebang starts anew!
Try to gather your firewood where you intend to burn it!
Transporting wood like mud on 4wd's should be a no no - other baddies like european wood borer etc can be spread by the same practices.
Lots of ground dwelling fauna lives in that dead branches / trunks we see on the ground - we are removing our native fauna's homes, when we cut that wood up for firewood and burn it.
Numbats like to live in hollow logs as do skinks etc, phascogales, mardo's and so on.
We all have to do our bit to save the native animals and trees!
Cheers!

Gee after reading that I might have to sell my 4b and not move from where I live???
I normally pick up fire wood when I am getting near to where I will be camping for the night or days. I useually just throw it on the roof as I dont carry a great deal of gear on the roof rack, changes the centre of gravity.
I will have to change my thinking later on when I travel to dryer parts of Oz as where I go at the present time has plenty of dead trees on the ground.
Happy traveling all.
Damien

Good call flywest. If we don't protect our land our grandkids won't have any to enjoy!
Hope the weather's kind to the campers this weekend, but hope it rains. A bit each way, just like betting on the 'Cup. ;}
