| Carnivore conservation planning on Borneo: identifying key carnivore landscapes, research priorities and conservation interventions | |
| 2016 Raffles bulletin of Zoology (33): 186-217 | |
Borneo harbours more endemic carnivores than does any other island in the world except Madagascar, and almost half of the Bornean carnivore species have been classified by The IUCN Red List of Threatened Species as globally threatened. Here, a systematic conservation planning framework highlighted key carnivore landscapes, conservation research and intervention priorities, and gaps in current knowledge of Bornean carnivore ecology. All single-species predictive habitat suitability index (HSI) models presented in this issue (20 species, comprising all carnivores on Borneo except otters [Lutrinae] and sun bear Helarctos malayanus) were standardised by converting HSI values into binary maps, and combined to derive species richness maps to discuss and delineate areas of conservation priority. The highest predicted carnivore species richness (defined here as the sum of the binary threshold maps), corresponds to interior lowland, upland and lower montane forest, whereas areas with lowest predicted species richness correspond to coastal lowlands already largely converted to oil palm plantations. The 12 proposed areas of conservation importance for carnivores focus on large landscapes and connectivity between subunits, many centred around the tri-national Heart of Borneo initiative, with additional areas for wetland/lowland species. A large proportion of these proposed conservation landscapes are being exploited for commercial purposes (e.g., logging concessions) and would, therefore, improve in conservation value if their management became more sustainable. The most important research priorities for Bornean carnivores are species resilience to altered and fragmented landscapes; under-surveyed regions; and the effects and relative intensity of hunting across the island. The most pressing conservation interventions include conservation research on the most threatened Bornean carnivores: the Bornean ferret badger Melogale everetti and Hose's civet Diplogale hosei (highland endemics), and the flat-headed cat Prionailurus planiceps and otter civet Cynogale bennettii (wetland specialists). Targeted conservation research and integration of research findings into decision-making, maintaining and restoring connectivity, raising awareness and improving enforcement and governance are also important conservation interventions. Although more resources are needed for conservation and research, the joint effort of scientists, conservationists and government authorities in the identification of key carnivore landscapes, research priorities and conservation issues which this study presents raises hope that more targeted conservation efforts for Bornean carnivores will follow in the future. |
