Western Province (Papua New Guinea)

The provincial government has, as with the governments of North Solomons, Chimbu and Northern provinces, sought to change the name of the province. The government uses the name Fly River Provincial Government; however, this remains unofficial as it has not been changed in the Constitution of Papua New Guinea.

Geography and ecology

Western Province covers 99,300 km² and is the largest province in Papua New Guinea by area. There are several large rivers that run through the province, including the Fly River and its tributaries the Strickland and Ok Tedi rivers. The largest lake in Papua New Guinea, Lake Murray, is also in Western Province.

This province is the only part of Papua New Guinea to hold land west of the 141°E line, which divides it from Indonesian Western New Guinea. This is a small section of territory bordered by the Fly River.

The Tonda Wildlife Management Area in the south-western corner of the province is a wetland of international importance. It is the largest protected area in Papua New Guinea.

The flora and fauna of much of Western Province resemble those of northern Australia. Flora includes eucalyptus, melaleuca, acacia, and banksias. Fauna includes wallabies, bandicoots, goannas, coastal taipans, and mound-building termites.

The drier, southern parts of the province have eucalyptus and melaleuca savannas (the Trans-Fly savanna and grasslands) that support large populations of birds, wallabies, and introduced deer, with dense rainforests being located to the north. The dry season is from July–November, while the wet season is from December–June. Sago cultivation dominates the wetter north, while yam cultivation dominates the drier south.
