In January to May 1998, the NCIP prepared Map indicating the ancestral domain claims by the IP’s in the DICADI area.  The area claimed by the IP’s is estimated to cover 91,872 has. Or 72% of the total land area of the three (3) municipalities of DICADI (Dinalungan, Casiguran and Dilasag).

These indigenous communities have immersed themselves with the general population were a peaceful co-existence is prevailing – where respect for customs and traditions between the IPs and the barangays population is observed.

 

People Ethnic Group:

The Agtas or Dumagats are the aborigine of the place. They are short and dark-skinned with kinky hairs.  They are nomadic and carefree with no permanent occupations.

In 1930’s, the government established schools for them where they can acquire elementary education, but they had no interest in learning.  Majority of these cultural minorities group still refuses to change their way of life.
