If the woodland was used for coppicing , as in hazel for fencing etc , the pigs would be kept away from the coppiced area for a year or two until the new growth had hardened off and developed a bark , to prevent it being eaten with everything else 如果森林里的植物是一些伏地植物,猪应该是远离这些地方一到两年直到这些植物变得坚硬,长的很高大,以防猪把这些还没有长成的植物给吃掉。
