Indigenous Ancestral Domain and Demographics

Mount Kalatungan is formally recognized as an Indigenous and Community Conserved Area (ICCA), a status that integrates ecological preservation with the traditional governance of the local inhabitants. This designation acknowledges the mountain not merely as a geological feature, but as a living ancestral domain managed by the indigenous peoples who have inhabited the slopes for generations. The ICCA framework provides a structured approach to conservation, allowing the Manobo, Talaandig, and Dumagat communities to exercise stewardship over the landscape while maintaining their cultural practices. The area covers a total of 3242 hectares, encompassing diverse ecosystems that range from lowland forests to the high-altitude grasslands near the summit. This extensive territory serves as a critical buffer zone for the surrounding municipalities, particularly Talakag, and plays a significant role in the regional hydrology of Bukidnon.

Demographic Profile

The human population within the Mount Kalatungan ancestral domain is relatively small, reflecting the traditional, low-density settlement patterns of the indigenous groups. As of 2015, the area was home to 2652 people, distributed across 531 households. This demographic structure indicates an average household size of approximately five individuals, which is consistent with the extended family structures often found in Manobo and Talaandig communities. The population is composed of three primary ethnic groups: the Manobo, the Talaandig, and the Dumagat. Each group contributes distinct cultural traditions, linguistic nuances, and agricultural practices to the communal life on the mountain. The Manobo, who refer to the volcano as Keretungan, hold significant historical ties to the central and eastern slopes. The Talaandig communities are traditionally associated with the western and northern flanks, while the Dumagat populations are often found in the transitional forest zones. This multi-ethnic composition requires coordinated governance mechanisms to manage shared resources such as water sources, grazing lands, and forest products.
