Oliver’s warty pig (Sus oliveri) - Endangered


The Oliver’s warty pig (OWP) is endemic to the island of Mindoro and listed as Endangered on the IUCN Red List, with a decreasing trend. No information is available on breeding biology, habitat preferences, territory range, behaviour and population size. Likely threats include habitat loss and hunting for food, local bushmeat trade, indigenous cultural ceremonies and hybridisation with free-ranging domestic pigs. Due to an insufficient knowledge of the species status of all wild Philippine pigs, we started with a genetic study to investigate whether the OWP can be seen as separate species. …. further information


What can ANB achieve?


The project’s outcome will be an improved understanding how Philippine wild pigs are related, the confirmation whether OWP can be seen as true species, and give a head start for the future conservation of the species by seeking a basic understanding about the pigs’ ecology and behaviour.

Degree of relationship between wild pigs in the Philippines


In co-operation with the Central Mindanao University, ANB started a genetic project on the taxonomy of the different wild pig species in the Philippines.
