This wetland restoration project isrecommended because the project can provide significant improvements to wetland vegetation,enhance the adjoining recreational area, and possibly provide increased habitat for fish andinvertebrates.The costs associated with the restoration of the mangrove forest would primary be associatedwith the initial clearing of solid waste material from the lower reach of Vaipito Stream. Morespecifically, the cleanup would be made between the stream mouth and the Route 1 crossing ofVaipito Stream. The subsequent collection and planting of mangrove, ifi, and falaga treecuttings would be carried out by the ASCC Land Grant Program.These estimated cost associated with the initial clearing of the Vaipito Stream mouth and theupstream area would be $2,036 (Table 6-7). The planting of mangrove and native riparian treeswould cost an estimated $5,251 (Table 6-8). Consequently, the total project cost anticipatedfor the overall project is roughly $7,287.American Samoa Wetland/Stream Restoration and Enhancement PlanFebruary 2001, Vaipito Stream, Page 6-13
