Guy, 

Given that the tree defoliated during the growing season it probably will not recover next year. If it is in no danger of failing due to severed roots it may be worth waiting to see if it leafs out.

These links are to articles related to root function.

Hi all, 
  
I received a request for service from a resident here in the City of Langley. There is an A. platanoides in his front yard approx 30 years of age and in good health…or it was. 
He says it defoliated approximately two months ago. Last night he called the Natural gas company as he and his neighbors had evidence of a gas leak in his front yard. They dug up and repaired the leak. He figures this leak may have been on going for a couple of months, as they smelt gas of and on over that period. The soil is going to be removed (just the stuff they excavated) and replaced. When I arrived the smell was incredible…so much so that I thought it was still leaking but it was coming from the contaminated soil. I understand that the natural gas will deplete the soil of oxygen. The actual leak and excavation was/is approximately 8 meters from the trunk and just outside of the drip line. My question is what effects will this have on the long term health of the tree? I am going to investigate into the health of the tree to the best of my knowledge later in the week but was looking for some insight on this situation. Any help would be greatly appreciated.
