[CANUFNET] Fwd: Roots causing damage to Gas and Oil pipelines

[Weir, David]

FASLA member James Urban author of "Up By Roots: Healthy Soils And Roots
In The Built Environment" available through the ISA would be another
person likely to have some experience in this area.

Sorry don't have any contact info for him, maybe try google...

Contact Ed Gilman at the University of Florida.

This guy has some serious knowledge on tree roots and their habits.  He
does seminars on tree roots across North America. If you have a chance
to hear him it's well worth it.

This decision could be precedence setting, even for homeowners.
