With land use change rapidly increasing in Asia, conservation prioritization has emerged as an important tool identifying critical landscapes for biodiversity to safeguard them from human pressures. In Peninsular Malaysia, the Malaysian Nature Society (MNS/BirdLife Malaysia) developed a set of Criteria identify Important Hornbill Landscapes (IHLs) – hornbill hotspots which are priority sites Malaysia and serve inform planning action. Application so far been restricted thus this study, we adapt it Sarawak, state Borneo that supports 80% species diversity country. We expand on methodology using Maximum Entropy Species Distribution Modelling (MaxEnt), validate Criteria's applicability potential IHLs Sarawak. Our data sources included literature reviews, citizen science databases interviews. Expectedly, survey effort was spatially biased. identified eight IHLs, mostly concentrated eastern across national parks, wildlife sanctuaries forest management units. Existing published distribution habitats Sarawak corroborated with our MaxEnt outputs aligned results IHL Criteria-based assessment, validating latter supporting its additionally six based confirmed value pairing such exercise. To knowledge, study not only demonstrates significance combining identification, but also represents first application outside Malaysia. findings can, therefore, case future applications potentially other parts Asia.
