Population justification: Ferguson-Lees and Christie (2001) suggest that a six-figure population would be realistic. The population in the Tibetan Plateau, which consists of c.80% of the breeding population, has been estimated at c.230,000 individuals, equating to c.153,000 mature individuals (Lu et al. 2009). Assuming a similar density across the rest of the species's range, a very preliminary estimate of global population is therefore c.290,000 (Lu et al. 2009). It is placed in the band for 100,000-499,999 individuals, assumed to equate to c.66,000-334,000 mature individuals.
Trend justification: Population trends of this species have not been well studied across most of its range, however it is suspected to undergo a decline of 25-29% over the next three generations, owing to the expected impacts of diclofenac use in livestock. Veterinary use of diclofenac is less common within the breeding range of G. himalayensis so adults are unlikely to be exposed, but juveniles may be when they migrate to lowland areas of India, Nepal, Bangladesh and Pakistan (Das et al. 2010; Bothat et al. 2017).
Surveys in Upper Mustang, Nepal, during 2002-2005 revealed a c.70% population decline (Acharya et al. 2009), but following the ban on veterinary use of diclofenac in 2006, the population in this area showed a partial recovery (Paudel et al. 2015). However, vultures continue to die from diclofenac poisoning (Nambirajan et al. 2018), and other threats such as food shortages may also be causing declines in some areas. Siddique & Khan (2016) recorded a 37% reduction in populations at nesting sites and a 21% reduction in individuals counted during transects in Azad Jammu and Kashmir, Pakistan, during 2005-2010. Although this decline may have been due partly to a large earthquake that occurred in the survey area in 2005, a steep decline in the number of livestock and increased shrub cover reducing visibility of carcasses from the air was also thought to have played a role (Siddique & Khan 2016). Recent surveys in Nepal and Pakistan found that 76% and 60% of respondents respectively agreed with the statement that vulture populations were decreasing in their area (Joshi et al. 2016). The species's population appears to be stable in Dehradun District, Uttarakhand, India (A. P. Singh in litt. 2014), and in the Tibetan Plateau (Lu et al. 2009).
