Replacement of native forests by exotic monoculture plantations is the principal driver of land change in central Chile; it reduces the richness and abundance of native mammals. The presence of shrub vegetation in mature pine plantation enhances habitat quality for small mammals. However, the role of structural complexity of shrub vegetation in young pine plantations after clearcutting remains unknown. Since plantations are managed by clearcutting, young pine plantations act as a barrier to movement of forest species. We tested if shrub vegetation contributes to rewilding harvested areas, assessing the movements of the long-haired field mouse (Abrothrix longipilis), a forest rodent, from native forest or mature pine plantations into young pine plantations. We evaluated habitat use at the edge of contrasting habitats, young pine plantations, and native forest or mature pine plantations. Habitat use was higher in young plantations that have shrub vegetation than those that have no shrubs. The long-haired field mouse is willing to use young plantations when shrub vegetation is developed.

清除荒野：灌木植被作为森林专家行动的促进者

智利中部土地改变的主要驱动力是外来单一种植人工林取代本地森林；它减少了天然哺乳动物的丰富度和丰度。成熟的松树人工林中灌木植被的存在提高了小型哺乳动物的栖息地质量。然而，在清除后的松树人工林中灌木植被的结构复杂性的作用仍然未知。由于人工林是通过砍伐进行管理的，因此，松树幼林成为阻碍森林物种移动的障碍。我们测试了灌木丛植被是否有助于使收割区荒野重生，从而评估了长毛田鼠（Abrothrix longipilis），这是一种森林啮齿动物，从原生森林或成熟的松树人工林变成年轻的松树人工林。我们评估了对比生境，年轻的松树人工林以及原生森林或成熟的松树人工林边缘的生境利用。在具有灌木植被的年轻人工林中，生境的使用要比没有灌木的人工林高。当灌木丛植被发达时，长毛田鼠愿意使用幼小的人工林。
