Long-term resource management activities associated with the restoration of the Aoa wetlandshould include the seasonal monitoring of selected resource characteristics and periodic sitemaintenance.Resource MonitoringThe process of resource monitoring will involve completion of the following steps by ASEPA,ASCMP, or other ASG agency staff:• Prepare a field map of restoration and enhancement site from available digital files inthe American Samoa GIS.• Go to the restoration and enhancement site and collect information summarized on fieldmonitoring worksheet.• Upon return to office from the field, incorporate new spatial data, topographic features,and resource conditions within the American Samoa GIS as points, lines, or polygons.• When desired, expand attribute tables for points, lines and polygons to enhance thedescription of resource characteristics and changes.• Make an annual evaluation of selected resource conditions that analyzes theeffectiveness of the overall restoration and enhancement project.Long term monitoring of the Aoa wetland restoration project will require periodic examinationsof:• General wetland/stream hydrology;• Stream channel modifications;• the survival of new mangrove propagules and riparian tree seedlings;• type and number of aquatic fish and invertebrates in the Tapua Stream estuary; and,• changes in adjoining land uses.The types of information needed, monitoring frequency, monitoring locations, and evaluationparameters are summarized in Table 4-8. A field work sheet or checklist, which can be used inthe field, is provided in Table 4-9.Future resource monitoring can be effectively performed through bi-annual site visits to theAoa wetland. This approach will enable comparisons during wet (December through March)and dry (April through November) seasons of the year. Additional visits should also take placeduring and/or following significant stormwater events that may be generated from periods ofsignificant rainfall.The availability of the American Samoa geographical information system enables theincorporation of most all resource monitoring information within the GIS. Field data can besummarized in attribute tables or databases. Digital photos can be linked to digital maps of therestoration site.Vehicular and pedestrian access to selected monitoring stations is largely dependent upon thecooperation and authorization of local residents and the Aoa Village Council. Assuming thatresidents cooperatively permit periodic access for long-term resource monitoring, monitoringshould take place along the following two stream segments (Figure 4-4):TABLE 4-8American Samoa Wetland/Stream Restoration and Enhancement PlanFebruary 2001, Aoa Wetland, Page 4-16
