Bawean Warty Pig (Sus blouchi) - Endangered

The Bawean warty pig (Sus blouchi) is on the IUCN Red List as endangered but still covered as a sub-species under the Java warty pig as Sus verrucosus ssp. blouchi. Unfortenatly its not protected by Indonesian law. Recently we have determined a full species status, making it the most isolated wild pig species in the world. … further information

According to the camera trap data, only about 172–377 animals live on Bawean island and the population trend is unknown
The species is not legally protected by Indonesian law. Hunting is still common and around 50 animals are killed annually.
Bawean warty pigs do cause crop damage in rice fields and are regarded as a pest

What can ANB achieve

We analysed DNA and prove the single species status of Bawean warty pig … further information
Assess movement pattern to better protect the species and prevent crop damage
Stop legal hunting and include Bawean warty pig into the list of protected species in Indonesia
Set up a captive breeding program and a back-up population

Jawan Warty Pig (Sus verrucosus) - Endangered

The Javan warty pig (Sus verrucosus) is endemic to Java and listed as Endangered on the IUCN Red List (IUCN 2016) … further information

Javan warty pigs are not protected, legal hunting is widespread and the population size is unknown
There is almost no information were the last isolated, small populations are left on Java
We do not have reliable data on habitat requirements and space use pattern
Hybridisation between the Java warty pig and the common and abundant Indonesian wild boar (Sus scrofa vitattus) is a serious thread … further information

What can ANB achieve?

We can give support to active conservation programs on Java. The Javan Species Recovery Programme (JaSpeR) currently investigates the last distribution areas of the Javan warty pig, the impact of hunting pressure and is carrying out solutions to protect the species. At the same time ANB analyses the “pureness” of the last remaning populations.

Develop a "field guide" with morphological descriptions of typical pure and hybrid Warty pigs detected by genetic methods.
Provide knowledge on essential habitat requirements and movement pattern to develop management plans for conservation and give advise to ongoing re-introduction programs.
Raise awareness in Indonesia about the critical situation of the Java Warty Pig in order to stop legal hunting and protect the last remaining populations.
