You need to move your sheep, down to the logs to move them along the river, then up onto the hay.
You could move them down to the grass then across the logs to the grass on the other side then over logs again to the hay, but that seems harder to get.
While moving your sheep across, you also need to gather the crops. If you match rows on the grass they have more value, but you need to increase value on all rows before you gather them. Otherwise you won't have enough moves to get all you need.
