Geographic Range
|
Range Description:
|
Rhinoplax vigil is confined to the Sundaic lowlands, where it is known from south Tenasserim, Myanmar, peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Singapore, Kalimantan and Sumatra, Indonesia and Brunei, in semi-evergreen and evergreen lowland forest to 1,500 m. Forest destruction in the Sundaic lowlands of Indonesia has been so extensive that all primary formations are expected to disappear by 2010, and the situation is little different in Malaysia. However, the species's ability to persist at higher elevations, where forest destruction has been less severe, means that its decline has been less rapid. It is also threatened by hunting, particularly for its casque, and its population should therefore be monitored carefully. CITES Appendix I.
