Vancouver Park Board spokesman Howard Normann says it happened in the dead of night in the 500 block of West 29th with no one immediately noticing what had been done.
"I think this was done with maybe with a re-chargeable power tool, very fine blade, probably 10 to 15 minutes at the most," he said. "If you know those kind of tools they're not that loud — and I don't think people would ever expect something like that would be happening."
The trees were four-year-old maples standing about three to 4.5 metres tall.
