Manupeu Tanah Daru National Park: Protected Landscape Identity and Regional Geography in East Nusa Tenggara

Manupeu Tanah Daru National Park is best known for its exceptional endemism. The park protects the Sumba yellow-crested cockatoo, one of Indonesia's most threatened parrots, and the Sumba hornbill, a striking bird found only on this island. The protection of these endemic bird species, along with six other Sumba-specific bird taxa, makes the park internationally significant for avian conservation. The park also preserves seven endemic butterfly species, representing one of the most significant lepidoptera populations in the Lesser Sunda Islands. The Lapopu waterfall, one of the largest waterfalls in the region, provides a notable scenic attraction within the park boundaries.

Manupeu Tanah Daru National Park was officially established in 1998 through the Ministry of Forestry Decree Number SK.576/Kpts-II/1998. The designation came after growing recognition that Sumba's lowland forests were disappearing at an alarming rate due to agricultural expansion, logging, and other human pressures. Prior to national park status, the area existed as a protected forest zone, but the formal protection under national park status provided stronger legal framework for conservation. The establishment reflected Indonesia's broader commitment to expanding its protected area network during the late 1990s. Since designation, management has been the responsibility of the Ministry of Environment and Forestry, with park headquarters located near Waikabubak, the main city in West Sumba district. The park remains one of the younger national parks in Indonesia, and its relatively recent establishment means that conservation infrastructure and visitor services continue to develop.

The landscape of Manupeu Tanah Daru National Park is characterized by rolling hills and steep slopes that rise from the island's coastal plains to elevations of approximately 600 meters in the forest interior, with the highest points reaching 918 meters above sea level. The terrain consists of heavily dissected ridgelines and valleys that create a complex topography typical of tropical islands with monsoonal climate patterns. The park encompasses catchments and drainages that feed streams flowing toward the coast, and several notable waterfalls mark where these watercourses drop over exposed rock faces. The Lapopu waterfall stands as one of the most impressive natural features in the park. Beyond the forest, the park also includes coastal areas with beaches such as Maloba, Aili, Marababakul, Hipi, and Konda, providing a contrast between the forested interior and the island's shoreline ecosystems.

The park protects one of the last remaining examples of Sumba's lowland forest ecosystems, a habitat type that has been extensively cleared across the island for agriculture and settlements. The forest vegetation includes approximately 118 documented plant species representing both deciduous and evergreen components. The tree canopy is dominated by species including Toona sureni, Sterculia foetida, Schleichera oleosa, Alstonia scholaris, and various Syzygium species. The understory contains a mix of shrubs and smaller trees, with invasive species like Lantana camara present in some areas. The forest supports a complex ecological community that has evolved in isolation on Sumba, resulting in the high degree of endemism that makes this park particularly significant. The transition from coastal to interior habitats creates distinct ecological zones within the park, each supporting different species assemblages.

The wildlife of Manupeu Tanah Daru National Park is distinguished by remarkable endemism, with seven bird species found exclusively on Sumba island. The most notable of these is the Sumba yellow-crested cockatoo, a critically endangered species that survives in significant populations only within this park and surrounding forested areas. The Sumba hornbill, another endemic species, is among the most sought-after birds by ornithologists visiting the park. Additional endemic bird species include the Sumba green pigeon, Sumba flycatcher, Sumba cicadabird, and apricot-breasted sunbird. Together, these 87 bird species represent a remarkable concentration of avifauna for such a limited area. The park also protects 57 butterfly species, including seven endemics such as Papilio neumoegenii, Ideopsis oberthurii, and Delias fasciata. This lepidoptera diversity further underscores the island's significance as a center of endemism in the Wallacea region.

Manupeu Tanah Daru National Park plays a crucial role in conserving one of Indonesia's most endemic-rich forest ecosystems. The park protects habitat for multiple threatened species, most notably the Sumba yellow-crested cockatoo, which faces severe threats from habitat loss and illegal trapping for the cage bird trade. The Sumba hornbill is similarly endangered and depends on the forest interior that the park safeguards. As the representative of the last significant tracts of Sumba's lowland forest, the park serves as a refuge for species that cannot survive in the degraded agricultural landscapes that dominate most of the island. Conservation challenges include managing the boundary between park protection and the needs of local communities who depend on the surrounding land for agriculture and grazing. The park's relatively recent establishment and limited infrastructure present ongoing challenges for effective management and enforcement.

The park lies within a region of strong cultural significance on Sumba island, where traditional village life and ancient customs remain integral to daily life. Near the park headquarters in the Waikabubak area, visitors can observe traditional carved stone tombs that represent important social and spiritual markers in Sumba culture, with sites such as Kadung Tana, Watu Karagata, and Bulu Peka Mila demonstrating the island's rich mortuary traditions. The Pasola ritual, a dramatic traditional ceremony involving horsemen with wooden spears, takes place in nearby districts during February and March and represents one of the most significant cultural events in the region. Local communities surrounding the park practice traditional agriculture and maintain connections to the forest through resource use and cultural practices. Visitor accommodations through community-managed homestays provide opportunities for cultural exchange while supporting local livelihoods.

Manupeu Tanah Daru National Park offers a combination of forest wildlife, endemic species, and natural scenery that distinguishes it among Indonesia's protected areas. The opportunity to observe the Sumba yellow-crested cockatoo and Sumba hornbill in their natural habitat draws ornithologists and wildlife enthusiasts from around the world. The park's waterfalls, particularly Lapopu, provide scenic attractions that complement the biological highlights. The mix of forest and coastal ecosystems allows visitors to experience both inland and shoreline environments within a single protected area. The proximity to traditional Sumba villages and cultural sites adds dimension to visits, especially for those interested in the intersection of nature and culture in eastern Indonesia.

The optimal visiting season for Manupeu Tanah Daru National Park spans two periods: March through June and October through December. These months correspond to the drier seasons when conditions are most favorable for wildlife viewing and forest exploration. The wetter months can make some trails difficult to navigate and may reduce visibility for birdwatching. The park's location on Sumba means that visiting during the dry season provides more comfortable conditions for outdoor activities. Visitors should note that facilities within the park remain limited, and most travelers combine a park visit with cultural exploration of Sumba island, often arriving with expectations shaped by their broader itinerary.
