The bison got a full round bale to play with, but it was carefully placed in an eroded ditch. In the process of using the bale as a neck scratcher, a heavy bag, and an afternoon snack, they are beating down the vertical edges of the ditch and breaking up the crust on the top of the soil. This provides the perfect surface for seeds to germinate and hold the soil in place. We are using the animals rather than machines to reshape the landscape and to keep our soil intact.
