How can I non-destructively remove hardwood transition strips?
It's really hard to see but it looks like your moulding is a peice of your hardwood flooring with a relief cut to fit the tlie under it. If the flooring guy put that peice down before the rest of the room (that's how I would do it) it would have nails closer to the hardwood side with a towards the tile from top to bottom angle to them. To remove it without damaging it I would use a small but sturdy flatbars with a lever point under it as close to the threshold as possible and push down firmly working the peice up from one end to the other.
