Outline of Final Research Achievements

Settlement probabilities of woody pioneer species were improved in the gap formed by mass mortality of oak trees. Effects of debarking by deer were limited, but their foraging affect understory vegetation and regeneration of the studied forest. Triadica sebifera and Symplocos prunifolia, pioneer and deer-unpalatable species, grew in the gap. Combination of oak death and deer foraging pressure benefits such species. The regeneration seems to be in progress, but its process may differ from the normal one.
