It’s usually easy to determine if a tree is truly dead or well on its way to failure and needs to be removed. “A tree is dead if it has had no green leaves for a full growing season."
“It needs serious attention if it has new, unsealed gaping wounds or long vertical cracks in the trunk or abnormally peeling bark, multiple branches with no living buds and ‘fruiting bodies,’ which are types of fungi, growing at the bottom of the trunk near or along with the tree’s roots.”
Another circumstance that will likely warrant removal is if the entire trunk is leaning 30 degrees or more off-center. However, determining whether or not to remove a tree becomes more complicated if the tree is still living but has been badly damaged or is in a state of poor health or decay.
“Again, a tree removal Sydney has the knowledge and experience to evaluate the health of the tree and help you decide if it can be saved or should be removed."
