We have had a similar DNA ID service available here following research at Melb Uni, though that was back in 2005, not sure if it is still being done there, was costly $500-$900 starting price (I think from memory...please don't get mad Melb Uni if thats wrong
)
Steve, if you're faced with a situation over there when you need other practical options than the removal valuable (some would say priceless!) vet trees try either Cheshire Woodlands Poynton, or the ArborCentre in Bath they are both excellent consutancy firms where the emphasis is the real situation between tree and environment rather than any prejudicial starting point.
