[CANUFNET] How big a tree can be moved? (Without killing it that is)

[Julian Dunster]

The size you describe should be simple enough. In reality I am not sure there is a limit to the the size that can be moved. I recently saw a very large ficus at Hong Kong disneyland that was moved on an enormous flat bed. In the US specialised companies regularly move enormous trees successfully. It just takes time and lots of money. Check the ISA web site and catologue. I think it's Watson and Himelinck that is the book you seek for more info.

  Hello All,

  I have been receiving conflicting information about the size of tree that can be successfully moved with a tree spade. I have heard anywhere from 18" dbh (from a contractor who wants to move the trees) to 5" dbh (from a developer who doesn't want to pay to move them). While there is no point in moving trees that are going to just give up the ghost, there must be some diameter above which the success rate drops off unacceptably. Just wondering if anyone has any experience in the matter.

  The trees in question are predominantly Colorado Blue Spruce planted ~20 years ago from nursery stock. They range in dbh from 7-11" and 5-7m in height.

  Does anyone have any information about the successful moving of large caliper trees or know of anyone or anywhere I can find this information? 

  Cheers,
