At first glance, Wasur National Park in Papua Selatan (South Papua) may appear to be a broad expanse of grassland and wetland stretching toward Indonesia’s eastern frontier. But closer inspection reveals a much richer landscape: kangaroos moving through savanna, cassowaries hidden in lowland forests, migratory birds using wetlands as seasonal habitat, and towering musamus structures rising from the earth.
Located in Merauke, Wasur has long been regarded as one of Papua’s important biodiversity strongholds. Wildlife is not the only thing that makes Wasur significant. The park also reflects the relationship between conservation, indigenous communities, local traditions, and nature-based tourism.
ANTARA described Wasur as a stronghold of biodiversity because of its collection of distinctive Papuan wildlife, including deer, kangaroos, and cassowaries. The park’s combination of ecological and cultural value has also made it an important destination for visitors seeking a different picture of Indonesia beyond its better-known tropical islands.
A Landscape Built Around Water, Grassland, and Forest
The scale of Wasur helps explain its ecological importance.
An ANTARA report citing the Ministry of Environment and Forestry described the national park as covering approximately 413,810 hectares at the time of the report. The same source recorded 80 mammal species, with 34 identified species and 32 identified as endemic to Papua. The park was also reported to contain 403 bird species, including 74 endemic Papuan species and 114 protected species.
The landscape changes dramatically with the seasons.
According to Donal Hutasoit, then head of Wasur National Park, almost half of the year can be dominated by water during the rainy season, while the landscape becomes much drier during the remainder of the year.
That seasonal cycle transforms the park. Grasslands and savannas where kangaroos and deer forage can become wetlands and pools. Rather than reducing the ecological value of the area, the changing water regime contributes to the diversity of habitats available to wildlife.
The vegetation is similarly varied. The area includes forests dominated by Melaleuca, mixed Melaleuca and Eucalyptus forests, coastal forests, seasonal forests, river-edge forests, mangroves, savanna, grasslands, and swamp grasslands. Rare orchids have also been found in the area, including Dendrobium yohanes, Dendrobium antenatum, and other Dendrobium species.
This combination makes Wasur more than a conventional forest destination. It is a mosaic of ecosystems shaped by water, fire, grassland, forest, and seasonal change.
Musamus: The Giant Structure Built by Tiny Creatures
Among Wasur’s most recognizable natural features is the musamus, often called the giant ant house by visitors.
The name can be misleading.
As reported by Kompas, musamus are not actually built by ants. They are structures created by termites belonging to the Macrotermes group. The termites construct the enormous mounds using dry grass, soil, and their own saliva, which acts as a binding material.
Some musamus in the Wasur area can reach around five meters in height, while others have a diameter of more than two meters. Their reddish-brown, ridged surfaces can resemble stalagmites rising from the savanna.
Inside, the structures contain networks of passages used by termite colonies. Kompas reported that these passages function not only as living spaces but also as ventilation systems that help regulate temperature inside the mound.
The architecture is particularly striking because it is created by colonies of tiny insects.
Millions of termites can inhabit a single structure, turning what might initially look like a pile of earth into a sophisticated biological habitat. Some of the structures are capable of withstanding considerable external pressure, including the movement of large animals and falling trees.
Musamus offers visitors one of the clearest examples of how Wasur’s tourism appeal directly connects to its ecology.
It is not an artificial monument. It is a living product of the ecosystem.
Wildlife on the Edge of Indonesia
Wildlife is at the heart of Wasur’s identity.
ANTARA’s October 2021 report described the park as a place where visitors can encounter several characteristic Papuan animals, including deer, kangaroos, and cassowaries.
The cassowary, in particular, represents one of the park’s most distinctive birds.
The large flightless bird inhabits parts of the lowland forests of southern Papua and is closely associated with the broader ecological landscape of New Guinea and northern Australia. Its presence illustrates the biological links between Papua and the Australian region.
Wasur also forms part of a wider wetland system that is important for birds. ANTARA reported that the park has been recognized as a Ramsar wetland site since 2006 and is part of the East Asian Australian Flyway network, reflecting its importance as a stopover and destination for migratory birds.
For an international audience, that point is particularly important.
Wasur is not an isolated conservation story. Its wetlands connect Papua to a much larger migratory system extending across East Asia and Australia. Birds arriving in the park are part of ecological movements that cross national borders.
That gives Wasur a significance extending well beyond Merauke.
Indigenous Communities at the Centre of Conservation
The people who live around and within the landscape are inseparable from the story of Wasur.
ANTARA reported that four indigenous communities have traditionally played an important role in managing natural resources in the national park. Their local knowledge forms part of the park’s social and cultural character.
Wiratno, then Director General of Conservation of Natural Resources and Ecosystems at the Ministry of Environment and Forestry, said the indigenous communities helped manage natural resources and represented part of the attraction for visitors.
That observation points to a broader model of conservation.
Protecting biodiversity does not necessarily mean separating people completely from nature. The conservation landscape in Wasur incorporates traditional knowledge and community participation.
Traditional leaders from the Kanume and Marori Men-Gey communities welcomed a visit from the House of Representatives Commission IV. The reception included the Gatsi traditional dance, reflecting the cultural dimension of the relationship between local communities and the conservation area.
The relationship between conservation and indigenous communities therefore carries two dimensions.
The first is practical. Communities possess knowledge about the land, wildlife, and natural resources.
The second is cultural. Their traditions impart meaning to the landscape and provide visitors with an opportunity to understand Papua through the experiences of the people who have lived with its ecosystems for generations.
Conservation and Tourism Can Move Together
Wasur’s biodiversity creates an obvious opportunity for nature tourism, but the value of tourism depends on how it is managed.
The park offers visitors something different from conventional beach tourism. Wetlands, savannas, forests, and cultural landscapes spread across the park, showcasing its attractions. Musamus provides an unusual geological and biological spectacle, while wildlife watching offers opportunities to observe animals characteristic of southern Papua.
The challenge is to ensure that tourism strengthens conservation rather than placing additional pressure on fragile habitats.
The information reported by ANTARA suggests that community participation is already an important component of the conservation story. Rare orchids, for example, have been cultivated by local communities with guidance from park authorities. Agustina Pramestuti, a member of Commission IV of the House of Representatives, praised the biodiversity of Wasur and said continued support for orchid cultivation was important to prevent rare species from disappearing.
This situation is where the economic potential of nature tourism becomes relevant.
When visitors come to see wildlife, landscapes, and indigenous culture, local communities can potentially participate through guiding, hospitality, cultural activities, and other services. At the same time, conservation agencies gain a stronger reason to maintain habitats that make the destination attractive.
However, it is essential to maintain a clear balance: tourism should support conservation, not the reverse.
Wasur and the Broader Story of Papua
Wasur also offers an important counterpoint to the way Papua is sometimes portrayed internationally.
News about Papua often focuses on political tensions, security issues, and development challenges. Those issues remain part of the region’s contemporary reality, but they do not define the whole of Papua.
Wasur presents another side of the province: an ecological landscape of global relevance, a place where biodiversity and indigenous culture exist alongside Indonesia’s conservation framework.
Its location in Papua Selatan also provides it a distinctive geographic role. The landscape sits within the wider ecological zone of southern New Guinea, close to the border with Papua New Guinea.
The park therefore provides a natural illustration of how environmental systems do not follow political boundaries.
Migratory birds move across countries. Wildlife habitats extend across landscapes. Seasonal water systems connect ecosystems. Indigenous knowledge has developed over generations in response to the same environment.
For Indonesia, protecting Wasur is consequently not simply a matter of preserving a tourist attraction. It is part of maintaining one of the country’s most distinctive ecological assets.
The Future of Wasur’s Biodiversity
The future of Wasur will depend on maintaining the relationship between conservation, local communities, and responsible tourism.
The park already has many of the elements that international ecotourism increasingly values: distinctive wildlife, rare ecosystems, dramatic landscapes, indigenous culture, and opportunities for educational travel.
But these assets are valuable precisely because they remain part of a functioning natural system.
The museum must remain a living structure rather than merely a photograph. Cassowaries need intact habitat rather than simply a place in a tourism brochure. Migratory birds need functioning wetlands. Indigenous communities need meaningful participation in the management of resources that surround their lives.
This makes conservation management an essential part of Wasur’s tourism future.
The experience of Wasur also suggests that development and conservation do not necessarily have to be competing goals. If managed carefully, tourism can create economic opportunities while encouraging the protection of the ecosystems that attract visitors in the first place.
Conclusion
Wasur National Park offers a rare combination of biodiversity, landscape, and culture.
Its savannas and wetlands provide habitat for distinctive Papuan wildlife. Its forests shelter cassowaries and other species. Its wetlands form part of an international migratory bird route. Its musculus reveals an extraordinary example of natural engineering. And its indigenous communities remain an important part of the cultural identity of the landscape.
For international visitors, Wasur can therefore serve as an introduction to a Papua that is ecological, cultural, and deeply connected to the wider natural world.
For Indonesia, its significance is equally clear. Protecting Wasur means preserving biodiversity while maintaining space for local communities and developing nature tourism responsibly.
The future of the park will ultimately be measured not only by the number of visitors it attracts but also by whether the forests remain healthy, wetlands continue to function, wildlife survives, and local communities remain meaningful partners in conservation.
That is the deeper story behind Wasur. It is not simply a place to visit. It is a living landscape that demonstrates how much of Papua’s natural heritage remains worth protecting.
