Whenever an object is placed by the player (including blueprints), it will set nearby trees to be deconstructed automatically (as if with a deconstruction planner). There is also a command to do this for already placed buildings (which could take a long time: /atdcall). There are 3 settings: 1. The radius to deconstruct trees. Default 15 tiles. 2. To optionally include rocks in the deconstruction. Default on. 3. To optionally also call the deconstruction when placing tiles (like landfill or concrete). Default off. It's not recommended to use this without a bot-start mod of some sort.
