Population justification: The population at known sites numbers at least eight individuals, but unsurveyed habitat may support "hundreds" (R. Green in litt. 2002). It is placed in the band 50-249 mature individuals, equating to 75-374 individuals in total, rounded here to 70-400 individuals.
Trend justification: This species is suspected to have declined at an unquantified rate over the last ten years, owing to unauthorised progress on the Telugu-Ganga canal and additional habitat loss and degradation outside Sri Lankamaleswara Wildlife Sanctuary as a result of an unfavourable grazing regime.
