The invasion and establishment of vegetation including herbs and trees was surveyed at eco-friendly stream constructed by different types of blocks in E-dong small stream, Cheongan-myon, Goesan-gun, Chungbuk Province. Among the nine different types of blocks, piles of native rock-2 and -3 stairs was the best construction block rather than other types of blocks judging from ecological point of view such as invasion and establishment of herbs and tree species. The subsequent types of blocks were the order of geo-green cell block, vegetation mat block and green-river block. Inadequate blocks comparing with other blocks were eco-friendly cobble block, environment block, environment H-block, vegetation constructed block and firefly block. By the comparison of similarity between each constructed block, it suggests that vegetation composition was converged to similar pattern after restoration of eco-friendly stream. And the biological spectrum such as dormancy form, growth form and migrule form was similar pattern in annual herbs, biennial herbs, perennial herbs and tree species. Four tree species of Salix gracilistyla, S. gilgiana, S. koreana and Robinia pseudo-acacia were invaded to the constructed blocks within the first year after restoration and tree species such as Lespedeza bicolor, Ligustrum ovalifolium, Rubus crataegifolius and Morus alba from second year after restoration. These tree species will grow and survive in successive years in conditions without any severe disturbance.
