The Wasur National Park forms part of the largest wetland in Merauke Regency, South Papua, Indonesia and has been one of the least disturbed by human activity.

Red Listed species known to be present in viable populations are southern crowned pigeon, New Guinea harpy eagle, dusky pademelon, black-necked stork, Fly River grassbird and little curlew.

Wasur shares a common border with Tonda Wildlife Management Area (WMA), another Ramsar site in neighbouring Papua New Guinea.

[4] In 1995 a Tri-National Wetlands Program has been initiated by WWF between Wasur NP, Tonda WMA and the Australian Kakadu National Park, which led to a Memorandum of Understanding between the three government conservation agencies in 2002.

[7] There are four groups of indigenous peoples living in the park, belonging to the tribes of Kanum, Marind, Marori Men-Gey and Yei, who rely on the area for food and their daily needs.

[4] Much of the park's natural flooded grassland systems are threatened by large scale changes to scrub and woodland as well as invasions of alien species such as water hyacinth and mimosa pigra.
