I like having wild horses around, they eat the "cheat grass" that catches fire real quick .
Ours won't eat it once it dries out.
But often they pull it out by the roots and just drop it. I find clumps of it lying around the pasture in late summer.
We have a patch of the nasty stuff on one hillside. I mowed most of it last fall, and this spring was really wet so some other stuff is now crowding it out a bit.
