The objective of this study was to develop an ecological administration and restoration on monitoring the naturally regenerated vegetation and growth change of planting tree type at the rear-slope of Jangheung multi-purpose dam using the recycling eco revegetation technique. The content of concrete monitoring included the change of flora and mean important percentage at plant community, maximal species diversity index, introduced plants, death rate, length of tree, tree crown, plant crown volume, plant coverage for two years to find the regeneration process of natural vegetation and growth change of planting patten were investigated. The results of this study are concluded as follows; First, the change of flora after wood chip mulching were decreased from 48 family and 149 species(first year) to 45 family and 132 species(second year) and vine plants were decreased two family and two species but influence of vine tree was extended and the naturalization index and urbanization index were decreased by 1.6%, 1.5%. Second, the change of dominant species were not appeared at plant communities and the change of maximal species diversity index at plant community were increased to deciduous hardwood communities and edge vegetation community and pinus densiflora communities were not variation but root-stocks of native trees plots were a tend to decreased. Third, introduced tree at plant communities were appeared to deciduous hardwood communities(17 species, 105 tree) and next pinus densiflora communities(5 species, 21 tree), and next edge communities(5 species, 21 tree) and next root-stocks of native trees communities(8 species, 13 tree). Fourth, death rate at planting tree type were appeared from 18.0%(first year) to 28.6%(second year) in transplant tree and root-stock of native trees were appeared from 9.0%(first year) to 18.0%(second year) and pot tree were appeared by 6.0%(second year), ground tree were appeared from 2.3%(first year) to 6.7%(second year). Fifth, the growth of tree length at planting tree type were higher root-stock of native tree(0.59m) and transplant tree(0.38m), pot tree(0.31m), ground tree (0.09m) and the growth of tree crown were higher transplant tree(1.56㎡), ground tree(1.04m), root-stock of plant(0.74㎡), pot tree(0.66㎡). Sixth, the change of tree crown cover, plant crown volume were higher ground tree(6.71%, 0.127㎥/㎡), transplant tree(3.34%, 0.085㎥/㎡), pot tree(2.65%, 0.024㎥/㎡), root-stock of native tree(0.47%, 0.005㎥/㎡)
