重新造林，即通过种植11种木本植物，将废弃的农田恢复为林地，可以为包括棕熊在内的野生动物提供栖息地（熊林奈，1758）。在棕熊密度很高的日本北部的Shiretoko世界遗产地，自20世纪70年代以来，人们一直在种植针叶树，以重新造林被遗弃的农田。在这个地区，从2000年开始首次观察到棕熊在挖掘蝉的仙女（Lyristes 15 bihamatus Motschulsky, 1861）。我们的初步观察表明，挖掘行为的出现可能与重新造林有关。我们研究了重新造林是否为棕熊提供了觅食的栖息地。我们发现挖掘只发生在恢复的针叶林中，而不是在天然林中。恢复林的19种蝉若虫密度均高于天然林。这些结果表明，废弃农田的重新造林通过增加雪域蝉若虫的可用性，为棕熊提供了觅食的栖息地
10 Reforestation, which converts abandoned farmland back into forestland by planting 11 woody species, can provide habitat for wildlife, including the brown bear ( Ursus arctos 12 Linnaeus, 1758). In the Shiretoko World Heritage site, northern Japan, where brown bears 13 occur at high density, conifers have been planted since the 1970s to reforest abandoned 14 farmland. In this area, brown bears were first observed digging for cicada nymphs ( Lyristes 15 bihamatus Motschulsky, 1861) from 2000. Our preliminary observations suggested the 16 emergence of digging behavior might be associated with reforestation. We examined 17 whether reforestation provided a foraging habitat for brown bears. We found that digging 18 occurred only within the restored conifer forests, but not within the natural forest. The 19 densities of cicada nymphs in the restored forests were higher than in the natural forest. 20 These results indicate that the reforestation of abandoned farmland provides a foraging 21 habitat for brown bears by increasing the availability of cicada nymphs in the Shiretoko
