Neighbors and SFPUC: Move oak tree? Other Topics, posted by Editor, The Almanac Online, on May 25, 2011 at 12:31 pm
Granny might have to move. Tree advocates and the SFPUC met Tuesday to discuss how to save the 65-foot heritage oak tree standing in the way of the Hetch Hetchy pipeline.

In a perfect world I hope we would do whatever required, regardless of costs, to save this beautiful heritage tree. But, given budgetary constraints that are our reality, I'd halt the research of tunneling, etc. to spare this tree and use the funds to save an restore an entire park: Flood Park. We have to prioritize and make tough choice choices that will be unpopular with some or many.

If this tree catches sudden oak death, affecting others just a few miles away, all this extra trouble will be for nothing. The tree in in an easement anyhow. Tough choice, but, oak does convert to very clean heat and falls within the index of Spare the Air smoke index. Romantic ideas cost money, so take up a collection from the tree huggers.

For those that are saddened by the fact that sometimes you can't save everything, even a beautiful oak tree, why not take a collection and plant many more baby Ganny trees elsewhere.

Oaks do not transplant well. They have about a 50% chance normally, but the larger they are the harder they are to transplant. this is a stupid idea. Put two off-sets in the pipe to go around the tree. It's not that complicated.

Dr Tony Mucciardi has developed a tool called the Tree Radar Unit (Web Link). It is an application of Ground Penetrating Radar adapted and calibrated to map tree roots underground (it can differentiate between roots and pipes, rebar, etc., largely based on water content of the object in question). I would suggest having a consulting arborist scan the roots using TRU so the depth and extent of the root system can be mapped. This would help create the most cost-effective strategy for tunnelling or lifting. I have used this tool many times and it is excellent, but being in Washington, DC am a bit far away to be of assistance. You have many excellent consultants locally. Thank you for efforts to save this tree. Mike Galvin, Registered Consulting Arborist #432, Casey Trees
