While a direct relationship between offtake and a population decline is not clear, even at the magnitude reported by Nowell 2016, it adds to the plausibility of a 10% decline over 3 generations (22.62 years).
Approach to Uncertainty The IUCN Red List Criteria are designed to incorporate the use of inference, suspicion and projection, to allow taxa to be assessed in the absence of detailed and complete data, which are rarely available across the entire range of a taxon; the absence of high-quality data should not deter attempts at applying the criteria (IUCN Standards and Petitions Subcommittee 2016). Loveridge (eds), Biology and Conservation of Wild Felids, pp.
While all these sets of estimates exclude dependent cubs, a population modelling exercise was carried out in 2015 to exclude young adults which may not be capable of breeding (Appendix 2 in the Supporting Information).
Model outputs for nine different scenarios were applied to the most conservative possible global population estimate available at the time (4,000), resulting in a number of mature individuals between 2,710 and 3,386.
If these poaching estimates are anywhere near accurate, this suggests that roughly 2-10% of the population could be poached annually. Justification: The Snow Leopard is assessed as Vulnerable because the global population is estimated to number more than 2,500 but fewer than 10,000 mature individuals, and there is an estimated and projected decline of at least 10% over 22.62 years (3 generations). The Late Miocene radiation of modern Felidae: a genetic assessment. There have been five attempts to compile national estimates, of varying data quality, to determine global Snow Leopard global population size. the opinion of a single expert, or the consensus view of a group of experts” (IUCN Standards and Petitions Subcommittee 2016). A community-based approach to mitigating livestock depredation by snow leopards. There is also a lack of hard data on overall population trends, which hinders estimates of the magnitude of any decline which rely on fragmentary evidence and are therefore largely speculative.
