Tame a herd of Lox and take them back to the meadows and dark forest, they'll go nuts and clear-cut the whole thing while hunting deer for sport.

...yep, that's my favorite solution as well. I've got a herd of Lox in a Meadow/Black Forest area and I just hop from Lox to Lox and charge around the meadow area on the outskirts, mowing down trees as I go and then I keep circling the grassy area on the edge, shaving off another layer of trees. I have noticed Lox don't damage some random Birch trees and perhaps Oak. I keep Riding my Lox around the 'racetrack', further bucking the fallen trees down to the individual logs...killing 2 birds with 1 stone. I get Ride XP, while generating the Wood resources to pickup at sundown.
