In response to the recent rediscovery of Barbourula kalimantanensis, which is currently the only known lungless frog, a number of biologically important aspects of the species were examined and its taxonomy and conservation status was reviewed. Based on the species ecological requirements, habitat restrictions and recent severe habitat loss, we propose to change the conservation status of Endangered B2ab(iii) to Vulnerable B1ab(iii) and earmark the species as a conservation flagship for the region and for Indonesia.
