Downed ancient tree is a resource node item in Valheim. Its in-game item ID is SwampTree1_log, which you can drop into the console with spawn SwampTree1_log to give yourself one — append a number like spawn SwampTree1_log 50 to spawn a stack. A downed Ancient tree is the trunk that remains after felling an Ancient tree in the Swamp. It can be chopped with a Bronze axe or better to yield additional Ancient bark. The spawn command requires cheats — enable them with devcommands after opening the console.
