Removing Trees from a map

[exikutioner 10]

So I am working on a little project, and have come across the need to remove some trees from a map. I know it is possible to "kill them at start" by using the Tree ID, however I cannot find anything that shows HOW to find the ID. Help!

Place a game logic over the trees and name it eg. logic1 and place the code in it's init box

things = nearestObjects [logic1,[],15]; {_x setdamage 1;} forEach things;

It will destroy all objects within a 15 radius, you can change that to what you require.

You won't be able to remove them you can only knock them down.
