Well, creating and maintaining a trail requires a bit of organization, or everyone tending to take the path of least resistance (see desire path on Wikipedia), and I doubt ogres are smart enough to travel single file like the sand people, organized enough to follow trails like a bee, or clever/delicate enough to take the path of least resistance. The idea of bushwhacking through the jungle every time you set out seems perfectly Ogrish to me.
