| Research Abstract |
The vegetation of alpine meadows was investigated at the Southern Japan Alps during 2011 to 2012. The results of research were compared with data from 1981 to 1982, and the change over 30 years and their causes were examined. Below the forest line, the vegetation of alpine meadows was dominated 30 years ago by Trollius riederianus var. japonicas, Ranunculus acris var. nipponicus, and so on. Two species, Veratum album ssp. oxysepalum var. alpestre and Ligularia dentate, recently grow there, their number increasing owing to feeding damage because the deer eat previously established species. Above forest limit, dominant species have not changed in each plot for 30 years. It is considered that the feeding damage of deer recently affects the area close to the forest line.
