Habitat fragmentation is one of the most important threats to species extinction, making it perhaps the most important contemporary conservation issue. Human development fragments natural habitats into patches - animals now need to cross dangerous habitat to travel from one patch to another. The kind of edge around habitat patches affects how easily animals do this and the stability of their populations hinges on how easily they can travel.

栖息地破碎化是物种灭绝的最重要威胁之一，使其成为当代最重要的保护问题。人类的发展将自然栖息地分割成斑块--动物现在需要穿越危险的栖息地才能从一个斑块到达另一个斑块。栖息地斑块周围的边缘影响动物这样做的容易程度，而它们种群的稳定性取决于它们旅行的容易程度。
