Abstract

In Singapore, the Critically Endangered Sunda pangolin Manis javanica is threatened by habitat loss and fragmentation, and road traffic collisions. To mitigate these threats, an understanding of its spatiotemporal distribution is needed, as identified in the National Conservation Strategy and Action Plan for the species. However, Sunda pangolin occurrence data are held in multiple separate databases, are typically collected using non-standardized methods, and often lack accurate location details. To compile a complete georeferenced database of Sunda pangolin records in Singapore, we consolidated occurrence data from heterogeneous databases and mainstream and social media, and converted locality descriptions into geographical coordinates. We demonstrate the use of this database to analyse data on rescued pangolins and those killed on roads, to aid conservation efforts in Singapore, and describe other potential applications. We georeferenced 482 records of pangolin sightings, rescues and roadkill for 1996–2021, finding an increase in all three over the study period. Roadkill and rescues occurred mostly in central and western Singapore, close to forested areas, and were predominantly of subadults and adult males. The data can be used to inform threat mitigation strategies, post-rescue release plans and further research. The database has already been used in practice, contributing to environmental impact assessments and conservation recommendations. Overall, this georeferenced database demonstrates the value of citizen science and collating wildlife data from multiple sources, and the methods used can be applied to other taxa to aid conservation strategies.

对新加坡的巽他穿山甲记录进行地理参照
在新加坡,极度濒危的巽他穿山甲 Manis javanica 正受到栖息地丧失和破碎化以及道路交通碰撞的威胁。为减轻这些威胁,需要了解该物种的时空分布情况,这也是该物种的国家保护战略和行动计划所确定的。然而,巽他穿山甲的出现数据存在于多个独立的数据库中,通常使用非标准化方法收集,而且往往缺乏准确的位置细节。为了编制一个完整的新加坡巽他穿山甲记录地理参照数据库,我们整合了来自不同数据库、主流媒体和社交媒体的出现数据,并将地点描述转换成地理坐标。我们演示了如何使用该数据库分析获救穿山甲和在道路上死亡穿山甲的数据,以帮助新加坡的保护工作,并介绍了其他潜在应用。我们对 1996-2021 年间的 482 条穿山甲目击、救助和路杀记录进行了地理坐标参考,发现在研究期间,这三种情况都有所增加。路杀和救助主要发生在新加坡中部和西部,靠近森林地区,主要是亚成体和成年雄性。这些数据可用于制定威胁缓解策略、救助后的释放计划和进一步研究。该数据库已在实践中得到应用,为环境影响评估和保护建议做出了贡献。总之,这个地理参照数据库展示了公民科学和从多个来源整理野生动物数据的价值,所使用的方法也可应用于其他类群,以帮助制定保护策略。
