Welcome back, dear sheep

Fortunately, the sheep of are visiting us again this year to graze on the university heath at WZU and thus maintain this gem. While lawn mowers chop up the grass and kill insects, the sheep on the one hand make sure that the insects can escape and on the other hand prepare the ground, leave a blade of grass here and there and provide places for new seeds to settle through their footfalls.
So now you not only get to hear the birds chirping when you open the windows, but you can also enjoy a bleat or two along the way.
