“…On the other hands, the agreed citizens to making Bawean deer as hunted animals come from old generations and migrants hunters (Rode-Margono et al, 2019). Further, some of the local traditions in the eastern of Bawean Island such as animal hunting for Ied Mubarak celebration day also responsible for a decrease of Bawean deers population.…”

Bawean deer (Axis kuhlii) is an Indonesian endemic-animal species that is categorized as Critically Endangered by IUCN and listed on Appendices I by CITES. This study aims to analyse Bawean citizens' perceptions and attitude to forest and the Bawean deer. The study was conducted by direct interviews and field observations. The respondents were determined by purposive sampling and quota sampling resulted in 191 respondents. The result indicates that the Bawean citizens have a low education level. Some of them finished education after elementary school (39.89%) and have not even completed this level 41.49%. Most of the Bawean citizens work as farmers (62.23%) and rely on the forest for their livelihoods, such as hunting for fresh meat. It is concluded that the educational background and well-being level of the Bawean citizens influence the perception of Bawean deer and wildlife reserve forest. Further, it will affect the existence and sustainability of the forest ecosystem. The citizens' attitudes towards the environment will be favourable if they have a high education level and forest supervision is held continuously.

“…Henceforth, we will follow the nomenclature proposed by Groves and Grubb (2011) to refer to the Bawean warty pig as S. blouchi . Owing to its small population size (172–377, Rademaker et al (2016); 234–467, Rode‐Margono et al (2020)) and its small geographic range, the Bawean warty pig was listed as ‘Endangered’ on the IUCN Red List (Rademaker, 2016; Rode‐Margono et al, 2020). As its Javan relative, it is not legally protected by Indonesian law, and threatened by illegal logging and retaliatory hunting in response to crop‐raiding (Nijman, 2003; Rode‐Margono et al, 2016, 2020).…”

Aim:The biodiversity of the Malay Archipelago is the product of the region's rich biogeographical history with periods of island connectivity and isolation during the Pleistocene glacial cycles. Here, the case of two endemic suid species, the Javan (Sus verrucosus) and Bawean (S. blouchi) warty pigs, was used to illustrate how biogeographic processes and recent anthropogenic pressures can shape demographic histories with significant implications for species conservation.Location: Malay Archipelago, with focus on Bawean and Java. Methods:We employed genome-wide single nucleotide polymorphisms from the Porcine SNP60 v2 BeadChip to assess interspecific genetic differentiation, to estimate divergence times and to perform demographic model selection. Results:In contrast to the hypothesis of recent divergence during the last glacial maximum, S. blouchi was found to have diverged from S. verrucosus at least 166 k years ago following a founder event. The contemporary S. blouchi population was characterised

The Togean Islands babirusa (Babyrousa togeanensis) is an Endangered wild pig species endemic to the Togean Archipelago, Indonesia. Despite its conservation status, our knowledge of the species is limited, which hampers conservation efforts. We here report the results of an island-wide camera trapping study, assessing the species’ demographic status and activity patterns. We sampled 103 camera stations distributed throughout the entire range of the species from July-October 2022. Through N-mixture modeling, we estimated the babirusa’s population size as 440 adult individuals (CI: 340–580), with a sex ratio of 1:2.3. The male babirusas were mostly solitary, but females were typically part of a group dominated by juveniles. Using multistate occupancy modeling, we also found the probability of reproductive babirusas being present in an occupied site was 0.74 ± SD 0.11, and the probability was higher with increasing distance to human settlement. Despite high human activities, the babirusa remained diurnal, with activities concentrated in the early morning and late afternoon. We suggest the IUCN Red List status of the Togean Islands babirusa should remain Endangered or shifted to Critically Endangered if the risk from potential African Swine Fever outbreak is considered.
