In-situ population monitoring for One Plan conservation of the endangered Javan warty pig

Project partners: Chester Zoo, DICE, JaSpeR, Cikananga Conservation Breeding Centre

The Javan Warty Pig (sus verrucosus) plays a pivotal role in seed dispersal and soil aeration within its habitat. However, significant threats from habitat fragmentation, hybridisation, human conflict, hunting and African Swine Fever have caused the Javan Warty Pig to be listed as Endangered on the IUCN Red List.

Conservation efforts are hindered by the lack of accurate population estimates. This project aims to address this with comprehensive in situ population monitoring via camera trap surveys. This will allow us to gather robust data on pig population trends, distribution and threats, thus better informing evidence-based conservation actions.

The collaboration between Chester Zoo, Cikananga Conservation Breeding Centre, the Javan Species Recovery Programme, and the Durrell Institute of Conservation and Ecology at the University of Kent, will conduct surveys in key locations of the Javan Warty Pig habitat. The data collected will help map pig abundance, identify critical areas and inform a One Plan multi-stakeholder workshop, to secure the future of the Javan Warty Pig in harmonious coexistence with the local communities.

Output and Outcomes:

• Camera traps surveys conducted across four primary and six secondary study sites.

• Initial data analysis results presented at Conservation Action Planning Workshop for the Javan and Bawean warty pigs (with full workshop report to be developed through 2026 with stakeholders).

• Engagement if local hunter groups to reduce hunting of Javan warty pig.
