As we are not very happy about the very common Nootka lupin flowing over hillsides and berryland, we decided to do a bit to stop her. At least close to our summerpasture. Wouldn't be too good if it would overtake the meadow. So we put up a fence where we allow our horses to climb and look for grass, which grows inbetween. The lupin obviously doesn't bear the horses stepping on it and starts to retreat. As you can see on the pic the horses where very busy looking for grass and didn't even want to come back down to their field.
