the lower bank above mean sea level. Mangroves were planted downstream of the foot bridgethat connects Pago Park and the vehicular parking area at Pago Plaza (Steele, 1996).Between Route 1 and the Vaipito Stream/Pago Stream confluence, an additional 205 trees wereplanted in late December, 1996. This restoration effort primarily included the planting of ifiand falaga. With the presence of more riparian vegetation along this stream segment, fewertrees were required for stream bank restoration (Steele, 1996).Despite these aggressive efforts, lower Vaipito Stream remains a highly degraded plant habitat.There is no utuutu or vao tuaniu, or native marsh vegetation along the stream banks. Therealso is very little falaga or ifi along the stream banks. Their absence, combined with thepresence of banana, mango, and kapok are indicative of disturbance.AQUATIC FISH AND INVERTEBRATESGeneralOn November 4, 1999, Charles Chong of the PPC field survey team made observations ofaquatic fish and invertebrates along selected portion of lower Vaipito Stream. An upland sitelocation was also investigated along Utumoa Stream, a significant upland tributary of VaipitoStream (Figure 6-3). His observations are summarized in the following paragraphs.Stream flows observed during the survey weregenerally fast-moving along the length of lowerVaipito Stream. A flow of about 2 to 3 cfs wasobserved at the Vaipito Stream mouth. Thestream mouth terminated with a fast riffleentering inner Pago Pago Harbor.A considerable amount of household garbageand other solid waste material was observedthrough much of the stream course.FishAn individual unidentified goby was observedalong Utumoa Stream. Three unidentifiedindividual gobies were documented in a poolbelow a small gage dam. With the exception ofthese fish, the only other fish observed along thestream were Poecilia.Kuhlia and Mugil spp. were abundant near theVaipito Stream mouth. However, Kuhlia spp. wasabsent upstream of the stream mouth.American Samoa Wetland/Stream Restoration and Enhancement PlanFebruary 2001, Vaipito Stream, Page 6-7
