Yes No Yes No2a Are stream flows entering the wetland? Yes No Yes Nob If no, what appears to be impeding stream discharge? Describe.3 a Is the wetland outlet, e.g., culvert or stream mouth, clear to permit stream discharge? Yes No Yes Nob If not, what appears to be impeding flow to the wetland outlet? Describe.STREAM CHANNEL MODIFICATIONS4 Has the stream bank been altered and with what material has the alteration been made? Yes No Yes No___ Basaltic rock wall___ Concrete wall___ Rock-filled gabions___ Other, please describe:5 If alteration has occurred, locate on field map _____ Check, when field map is so marked.6 a Do existing rock walls, concrete walls or gabions appear to have been damaged from pastor recent stormwater events? Yes No Yes Nob If so, where? (locate on field map) _____ Check, when field map is so marked7 a Is there evidence of bank erosion? Yes No Yes Nob If so, where? (locate on field map) _____ Check, when field map is so marked8 a Do you see evidence of a change in the stream flow path? Yes No Yes Nob If so, where?

Write in the measurement on each trapezoid.SURVIVAL OF NEW WETLAND PLANTS10 a Count number of surviving new taro plantsb Ask local resident to estimate annual production yield.

Recommended monitoring stations or sites should be used consistently unless unanticipatedevents, new land uses, or access issues prevent continued use. When necessary, changes in thelocation of monitoring stations should be documented and spatially located within theAmerican Samoa GIS. PPC has provided digital files for the Wetland and Stream Restorationand Enhancement Plan that provide a departure point for future resource monitoring in thevicinity of the Alao wetland.Digital photos should also be dated and subsequently incorporated into the digital photo albumfor the Alao fresh-water wetland. This will enable a long-term comparison of resourceinformation by ASG staff and consultants that may be used to perform long-term resourcemonitoring.Digital photos of taro production should also be supplemented with documentation of actualproduction yields from local residents. This information should be documented within acomputer spreadsheet that would be established for production data. This information wouldfacilitate future evaluations of taro production.Vehicular and pedestrian access to selected monitoring stations is largely dependent upon thecooperation and authorization of local residents. Traditional leaders of the Alao VillageCouncil should be contacted before any long-term monitoring activities are initiated and carriedout.Site MaintenancePeriodic site maintenance should take place within the Alao fresh-water wetland and lowerMulivaitele Stream approximately four times per year. Human disposal of solid wastes withinthe wetland and the Mulivaitele Stream channel is expected to represent the primary focus oflong-term site maintenance.A crew of three to four persons will be necessary to walk the length of the lower MulivaiteleStream channel within the inhabited village area. Through the use of machetes and weedeaters,the portions of the Mulivaitele Stream channel will require the periodic trimming ofvegetation. The collection of solid wastes will also be necessary to minimize obstructions tostream flow and potential reductions in channel capacity.American Samoa Wetland/Stream Restoration and Enhancement PlanFebruary 2001, Alao Wetland, Page 3-17
