A survey of Laufuti Stream, Tau Island, National Park of American Samoa
Cook RP. 2001. A survey of Laufuti Stream, Tau Island, National Park of American Samoa. Technical report NPS/NRWRD/NRTR-2001/290. National Park Service. Fort Collins, Colorado
Laufuti Stream is a complex interrupted perennial stream with a spring-fed lower section at sea level, an intermittent middle section, and a perennial upper section that percolates into volcanic rock. Sections are separated by faulting. The macrofauna consists primarily of tropical Pacific widespread amphidromous species, but the community is very different than those in streams in Tutuila. There is a diverse & abundant shrimp community, dominated by Macrobrachium latimanus, and a diverse alien-free fish community including Anguilla megastoma. There is vertical community zonation, complicated by the intermittent estuarine connection & waterfall zone. Water quality is high, and watershed is dominated by native forest. Laufuti is one of the most pristine & undisturbed streams in Americam Samoa.
