a grass question...what eats it down just one little area? beaver.. or horses?

[greybeard]

In a pasture about 8 total acres, I found one area about 20' diameter circle (more or less a circle anyway) that is just eaten down to the ground and all the rest is still tall with grass. Only thing in that pasture for the last 2-3 months has been 2 horses and they have only been in about 2 weeks, and I know horses will eat grass down to dirt but just in one little area??.

It wasn't like this a week ago when I drove over with my 4 wheeler.
This is in the same specific area the beavers have recently set up on.....would they be eating grass too?

The beaver works is between the crosstie fence post and the tree trunk.

Just seems odd, that it hasn't happened anywhere else that I've had those horses. I guess I need to move them before one of them steps off in one of the holes the beaver have dug up from their tunnels.

Horses will wear out one little area.

Deer will do the same thing.

That's how mine looked after the Army Worms came through.

I suspect that is where the beavers gathered grass to line their den.
