I've seen places like this with very few tracks in it. The trees prevent undergrowth and the forest floor is pretty much bare. If it ends where the trees end thats what its from. But I've also seen areas tore up with sign. If its that there should be a bunch of tracks.

One thought is it was a wintering area, in a hard snow,for them and they have moved on. Trailcamera is the way to find out if they still use the area.
