Wildlife corridors: barriers

Human structures such as roads, railway lines, fences, settlements, etc. cut up the landscape and restrict the wildlife when crossing the landscape or prevent wildlife migrations altogether. Intensively cultivated land can also be an insurmountable obstacle for individual animal species.诸如道路、铁路线路、围栏、居民点等人造设施会割裂自然景观，不仅限制野生动物的跨景观移动，更会彻底阻断其迁徙行为。集约耕作的土地对于特定动物物种而言，同样可能成为一道不可逾越的障碍。
