| Research Abstract |
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.
