Forests in Mt.Ohdaigahara, located on the Kii Peninsula in central Japan, has recently suffered deforestation caused by an increasing population of sika deer (Cervus nippon), which strip the bark of many coniferous trees, causing dieback. Canopy loss increased light inside the forest, allowing the forest floor to become densely covered with sasa grass, which grows well with more light. The dense covering of sasa grass inhibited conifer seedlings from growing and surviving on the forest floor. Seedlings were browsed by the deer. As a result, the forest in Mt.Ohdaigahara has been partly changed form coniferous forest to sasa grassland. The change from dense forest into sasa grassland affected the community structure and function of organisms. For example, a dense population of sika deer decreases the diversity and abundance of bird communities, but not increases the diversity or abundance of dung beetle assemblages through dung supply.

位于日本中部纪伊半岛的大岱原山的森林最近遭受了因西卡（Cervus nippon）数量增加而造成的森林砍伐，这些鹿剥去了许多针叶树的树皮，导致枯死。林冠损失增加了森林内的光线，使森林地面上密布着莎莎草，这种草在更多的光线下生长良好。茂密的碱蓬覆盖抑制了针叶树幼苗在林下的生长和存活。秧苗被鹿吃了。结果，大岱原山的森林已部分由针叶林转变为莎莎草原。从茂密森林到草地的变化影响了生物群落的结构和功能。例如，密集的西卡种群减少了鸟类群落的多样性和丰富度，但不会通过粪便供应增加蜣螂群落的多样性或丰富度。
