ABELLEN
The Ayta Abellen, a semi-nomadic group residing in the mountains of western Tarlac and parts of Zambales, primarily earn their income through charcoal production, upland rice farming, and occasional lowland fieldwork. Due to intermarriage with Ilokano lowlanders and the migration of Hambali Ayta after the Mt. Pinatubo eruption, the Abellen describe themselves as mixed and scattered, with only a few remote settlements remaining predominantly Abellen. Literacy among the Abellen is limited, especially in mountain areas, though some families in lowland barangays have literate members. Evangelical churches exist in barangays with lowlander populations, but few Abellen attend regularly. While three churches are led by Abellen pastors, there is little outreach to the remote mountain communities. To effectively share the gospel, translated Scripture in audio form and literacy materials are being developed and tested.

AMBALA
The Ayta Ambala Indigenous Peoples reside in the southern part of the Zambales Mountain Ranges, spanning areas in southwestern Pampanga, southern Zambales, and northern Bataan. Similar to other traditional Ayta communities, they continue to practice slash-and-burn agriculture, locally referred to as “gasak” and “kalaanan.” While urbanization has significantly influenced certain aspects of their way of life in recent years, the Ayta Ambala have managed to preserve their distinct cultural identity.

Mag-Antsi and Mag-Indi
The Ayta Mag-Antsi and Mag-Indi live in the central part of the Zambales Mountain Ranges, particularly in areas within Pampanga Province. While they have preserved much of their traditional culture, the evolving political, social, and economic conditions in the region have compelled them to adapt to the lowland lifestyle, especially that of the Kapampangan people.

MAGBEKEN
The Ayta Magbukon have inhabited the Bataan Peninsula since ancient times, with their name meaning “to separate” from other Ayta language groups. They have managed to retain significant portions of their ancestral lands and continue to coexist with the surrounding lowland communities. While development in the province has provided new opportunities, it has also brought irreversible changes to aspects of Ayta Magbukon culture, including their language.
