More specific monitoring of stream fauna should be made along Papa Stream in the vicinity ofthe station 1+00. Such monitoring should include the collection of driftnet samples of outgoinglarvae, at least two times per month, for 3-4 hour evening periods. The driftnets (150-200 ųmmesh) should be attached to rebar pounded into the stream substrata, or simply suspended fromtrees or bridges to that the net is at the surface of the water. The samples would subsequentlybe preserved in ethanol. The type and number of fish and crustaceans should be enumeratedusing a dissecting microscope. Use of the dissecting microscope will likely require a 2-3 daytraining class and the necessary equipment.Molluscs should be monitored by mark-recapture methodology, or quadrant counts at nightsince most are primarily nocturnal. Some training in these techniques is recommended.Site MaintenanceThe initial cleanup of lower Papa Stream will represent an important first step toward longtermstream enhancement. However, the initial cleanup is of limited benefit if it is notassociated with the implementation of a long-term maintenance strategy.Periodic site maintenance should take place along lower Papa Stream approximately four timesper year. Household wastes along the 1,200 feet of Papa Stream (station 1+00 through station12+00) are expected to represent the primary focus of long-term site maintenance.A crew of 10 persons will be necessary to periodically collect and remove discarded solidwaste material from the 1,200-foot segment of Papa Stream. Periodic cleanups would occurshortly after significant rainfall and stormwater events. Machetes and a weed-eater will berequired to periodically trim vegetation along selected portions of the stream channel.American Samoa Wetland/Stream Restoration and Enhancement PlanFebruary 2001, Papa Stream, Page 7-20
