樹砦の勇者 It's not a  direct  translation...but it's using the "Fortification" portion to make a title that makes sense...since Fortress and whatnot doesn't do so imo, heh.
 * 樹 - tree/shrub/bush/wood/timber
 * 砦 - fort/fortress/stronghold/fortification
 * 勇者 - Hero

It could probably be Wood Fortification...but I'd say it "feels" better the way it is. ^^
