Outline of Final Research Achievements

In the early stage, deer impact appeared trees < 3 cm in DBH, and the impact level could be evaluated by percentage of browsed seedlings. Deer browsed twigs at 50-150 cm in height in the early stage, and expanded the range to both upper and lower layers. Preferred species were browsed at first, and the other species were browsed after twigs of preferred species decreased. As a result, browsing line was formed. Shrubs recovered within 10 years following the establishment of deer exclosure after the disappearance of dwarf bamboo and tree seedlings, but seedlings of tree species recovered slowly. Deer population density should be kept in very low level for tree seedlings to grow up outside the deer exclosure.
