And ground out this bugger the other day. Took about 40 mins just to access it - thru 2 adjoining properties fences including a steep climb thru a vacant lot.
No prizes for guessing why it fell over...
Storm...NO
Act of God...NO
Gums are bad...NO
Homeowner excavated a 1.5 deep terrace into the soil profile only 1m away from the tree!
Roots and base had plenty of decay on that side!
