Total Salinity

The Purari River in Papua (Papua New Guinea) is a tropical river with ionic dominance similar to that of the world average river water, i.e. Ca > Mg > Na > K, and HCO3 > (SO4?) > Cl. As the sulphate concentration was not determined, the anionic trend still needs to be further investigated. The Na:Ca as well as the Ca + Mg:Na + K ionic ratios suggest that chemical weathering in the highlands is the dominant source of dissolved solids, and that it determines the chemistry of the lower course of the Purari River. Among the waters investigated, the Purari River, in its lower course, has a total salinity higher than that of the Sirinumu impoundment, and lower than that of the Sepik River. The low concentration of solutes in the Sirinumu impoundment near Port Moresby indicates that oligotrophication can be expected in reservoirs built on Papuan rivers.

Physical Impact

Since 1977 the Sepik River backwaters between Pagwi and Angoram in Papua New Guinea have become increasingly covered by the exotic water-fern Salvinia molesta. By May 1979, Salvinia covered about 80 km2. Water chemical analyses for dissolved substances give no evidence that nutrients in the Sepik River and ‘lagoons’ might become limiting enough to affect the Salvinia population. The physical impact of the plant is reflected especially in the decline of the fisheries for Saltfish Tilapia (Sarotherodon mossambicus), crocodile hunting, collection of sago-palm, and in the slowing down or complete elimination of water transport. As a consequence, people in a number of villages are unable to reach markets and children cannot go to schools.A programme of management has been formulated which will involve the United Nations, central and provincial governments, and local inhabitants. However, it should be understood that there is little chance of complete elimination of the weed from Sepik River backwaters.

Helicia woxvoldiana (Proteaceae) is described from the Sepik River basin in Papua New Guinea, from classical localities on the Kaiserin-Augusta-Fluss itinerary of 1912–13. The new species is a canopy myrmecophyte with the largest flowers in Papuasian Helicia.
