I would go with everything you have said. If you look in the hole there's a substancial amount of trunk left in there deep.
When you see blow overs like that USUALLY you see the root plate go over, a whole bundle of roots and soil and USUALLY it displays no tap root with gums like this.
The only thing that is hard to prove or debate-able is brown rot, most of the time you will see a slight white tinge or spotting. The natural colour of the grey gum innards is the colour you have circled. Is there a good way to easily field test brown rot?
The bigger gum behind it is going to go over too soo.
The large wound is old but the tree up the back has exactly the same wound. My hunch is machinery damage from years ago. This house is in Annerley so could be @60 years old easily but the wounds I do not think are that old. So not sure what happened there.
Also, the top 300mm to 400mm of soil is builders rubble and washed down junk. There were some old busted roots well under that fence posts concrete pour so they would have been the original flare maybe 500mm deep.
Pretty good stuff, I always like to check out blow overs and see what gives so you can get better a predicting others. |
