With the death toll officially capped at 210, over 10,000 people left homeless some after 6 weeks are returning to their homes. Undoubtedly one of the worst ever fire seasons in Australia's history. The arduous task of dealing with remaining dangerous trees is best left to professionals as pictured above. Ace Tree Management of the Dandenong ranges in Victoria have been getting their fair share of the dirty work, well equipped they fell and remove even burning trees.

Arborist Eric Frei stands at the end of only a limb that failed in June 2008 from a huge fig tree located at the 7Eleven at Sinnamon park in Brisbane. The tree just by the side of the footpath near the intersection of Goggs road and Seventeen Mile Rocks road still stands in a rapidly deteriorating condition according to arborists of Treeworld. Recent pictures show an abundance of fungal fruiting bodies now also located on large scaffold limbs, the canopy continues to thin indicating the decay is advancing.
Treeworld has repeatedly notified the 7Eleven franchise who since June 2008 have failed to respond. Tree crews who cleared the fallen limb also notified the owners who appear to have neither taken action or responded. Full details including many pictures are available for viewing and discussion here.
Tree photosynthesis, according to the study, most likely occurs when leaf temperatures are about 21C, with latitude or average growing-season temperature playing little, if any, role. This homeostasis of leaf temperature means that in colder climates leaf temperatures are elevated and in warmer climates tree leaves cool to reach optimal conditions for photosynthesis. Therefore, methods that assume leaf temperature is fixed to ambient air require new consideration.
"It is not surprising to think that a polar bear in northern Canada and a black bear in Florida have the same internal body temperature," Brent Helliker, professor of biology in the School of Arts and Sciences at Penn, said. "They are endothermic mammals like us ,and they generate their own heat. However, to think that a black spruce in Canada and a Caribbean pine in Puerto Rico have the same average leaf temperature is quite astonishing, particularly since trees are most definitely not endothermic. Our research suggests that they use a combination of purely physical phenomena -- like the cooling from water evaporation or the warming caused by packing a lot of leaves together -- to maintain what looks like leaf-temperature homeostasis."

Weed and feed products contain chemicals that can damage the root systems of trees. In Australia some natives can also be sensative to elements such as P (phosphorous). Many lawn fertilizers also have large amounts of N (nitrogen), whilst that can be a greening fertilizer it can cause rapid growth in trees at the expense of strength and defense ... Read more

The boom in websites focused on providing free information in the hope that you click on an ad and earn the owner some income is becoming the norm. Trouble is ...is the information you are receiving correct and accurate? In a detailed case study Treeworld take on Expert Village and their series of deadly videos, despite the producer not being a qualified arborist and a barrage of emails sent the site continues to display these dangerous practices. Video tutorials at the site are recieving solid approval votes from the public, who frankly don't know better... is your profession or trade also a victim of these Village Idiots? read more

If your back cuts look anything similar to the one pictured above then you need to change your ways. There is not one place that will teach it, or approve of it, in fact it goes against all OHS codes for tree felling. In a detailed well thought out thread on Tree World the physics of why supported with diagrams will explain the dangers.
