Paboya-Paneki

Paboya-Paneki, officially Taman Hutan Raya (Tahura) Sulawesi Tengah, is a grand forest park of approximately 81 square kilometres located immediately around and southeast of Palu, the capital of Central Sulawesi province, Indonesia, only about 8 kilometres from the city centre. First established in 1995 under Ministerial Decree SK No. 461/Kpts-II/1995 and boundary-confirmed in 1999, the park is managed by the Central Sulawesi provincial government. ^[1] A grand forest park (tahura) is a category of conservation area intended to combine biodiversity protection with public education, recreation, research, and the conservation of native and non-native plant collections. Its proximity to Palu makes it a readily accessible green space, protecting hills and forest that form an important backdrop and watershed for the densely settled Palu valley, while offering residents a nearby setting for nature appreciation.

The park's forests and hill habitats support a range of central Sulawesi wildlife, with fauna that may include macaques, cuscus, civets, wild pigs, and various small mammals, alongside a notable diversity of birds such as kingfishers, hornbills, sunbirds, and endemic forest species. Reptiles, amphibians, and butterflies and other insects are also present. As a tahura close to a major city, the park serves both as habitat for native species and as an accessible place for the public to encounter Sulawesi's distinctive wildlife. Its role as an urban-edge conservation area makes it valuable for environmental education about the island's endemic fauna.

Paboya-Paneki protects lowland and hill forest, including drier forest types characteristic of the Palu valley, which lies in a relative rain shadow. Vegetation includes mixed broadleaf trees, grasses and savanna-like patches on drier slopes, and denser forest in more sheltered or moister areas. As a grand forest park, it includes planted collections of native and introduced tree species used for education, research, and rehabilitation of degraded land. The plant communities help stabilise the hill slopes around Palu, reduce erosion, and protect the watershed in a region prone to dry conditions and land degradation.

The park lies on the hills bordering the Palu valley, a landscape dominated by the Palu-Koro fault, one of Indonesia's most active strike-slip fault systems, which runs through the region and has produced significant earthquakes including the devastating 2018 Mw 7.5 earthquake and tsunami that struck Palu city. ^[1] The terrain consists of uplifted and faulted rocks, with hill slopes flanking the elongated valley that the fault has helped shape. This active tectonic setting gives the area dramatic relief and makes it geologically significant, while also rendering the surrounding region susceptible to seismic events. Erosion of the hill slopes feeds sediment into the valley and influences soil and vegetation patterns within the park.

Reflecting its position in the rain-shadowed Palu valley, the park experiences a notably drier climate than much of tropical Sulawesi, with lower annual rainfall and a more pronounced dry season. Temperatures are warm to hot year-round, typically in the high twenties Celsius or above in the lowlands, with strong sunshine on exposed slopes. This relatively dry, warm climate shapes the park's drier forest and grassland vegetation and increases the importance of the park's role in watershed protection and reducing erosion in a region where water can be scarce during dry months.

The Palu valley is the heartland of the Kaili people, the principal indigenous group of Central Sulawesi, and has long supported settlement, irrigated agriculture, and trade centred on the city of Palu. The hills now within the park provided wood, grazing, and other resources to surrounding communities and have experienced pressure from expanding settlement and land use. The establishment of the tahura reflects efforts to conserve forest and watershed close to a growing urban centre while providing the public with educational and recreational access to nature in a culturally significant landscape.

Paboya-Paneki was first established as a grand forest park (Taman Hutan Raya) in 1995 under Ministerial Decree SK No. 461/Kpts-II/1995, with its boundaries confirmed and the area formally amalgamated in 1999 under Decree Number 24/Kpts-II/1999, covering the Poboya nature reserve, Paneki protected forest, and the Kapopo national reforestation area. ^[1] As a tahura, it is administered by the provincial government rather than the national conservation agency, distinguishing it from the cagar alam and suaka margasatwa elsewhere in the province. Its creation responded to the need to safeguard green space and water catchment close to the rapidly growing provincial capital and to offer residents accessible contact with the region's natural environment.

Being close to Palu and designed partly for public use, the park offers more accessible recreation than the province's strict reserves, with opportunities for nature walks, viewpoints over the Palu valley, birdwatching, and environmental education. Trails and facilities allow visitors to explore the hill forest and observe native plants and wildlife. The park's elevated terrain provides scenic outlooks toward the city and surrounding mountains. Its combination of accessibility, scenery, and conservation value makes it a popular local destination for residents seeking green space near the capital.

As a grand forest park near the provincial capital, Paboya-Paneki is among the more accessible protected areas in Central Sulawesi, lying only about 8 kilometres from Palu, which is served by Mutiara SIS Al-Jufri Airport and road connections across Sulawesi. Entrances are accessible from Paboya village (approximately 9 km east of Palu), Paneki village (approximately 10 km south), and Ngatabaru village. Visitors can reach the park easily by road, and some basic facilities such as trails, signage, and recreation areas are provided in line with its public function. Travellers should be mindful of the dry, hot climate and the region's seismic activity, and check current conditions and any access requirements with local authorities.

Conservation in Paboya-Paneki emphasises protecting the hill forest and watershed around Palu, controlling erosion, and rehabilitating degraded land in a dry, fire-prone setting, while accommodating public use. Management by the provincial government balances biodiversity protection with education and recreation, using the park to raise awareness of central Sulawesi's natural heritage among urban residents. Challenges include encroachment, gold mining pressure in the Poboya area, fire risk during the dry season, and urban expansion pressure from the surrounding city. Sustainable stewardship depends on reforestation, community engagement, and maintaining the park as a vital green lung and water catchment for the Palu valley.
