Population justification: In May 2020, an island-wide survey based on counts of displaying males at a stratified sample of sites estimated a population of 20,300 mature individuals on Hokkaido (Ura and Tajiri 2020). An additional 3,400-11,000 mature individuals are estimated to occur on Sakhalin (Hansen et al. 2020a) with much smaller numbers on Honshu. Another estimate, applying a trend correction to previous data, suggested a total population of 35,000 mature individuals (Hansen et al. 2022). To account for these uncertainties, the population is therefore estimated to number 20,000-39,000 mature individuals.

Trend justification: The population was previously suspected to be declining, but not at a rate that exceeded or approached the thresholds for listing as threatened; however, recent data indicate a sudden population reduction in Japan between 2018 and 2020. Based on counts of displaying males at a stratified sample of sites, an estimated 42% reduction (from 35,000 to 20,300 mature individuals) on Hokkaido (where the majority of the world population breeds) occurred between 2018 (Ura et al. 2018) and 2020 (Ura and Tajiri 2020). There is high confidence in the 2018 population size, which was similar to an estimate made in 1986 (Naarding 1986), and in the 2020 survey data, which mirrored the methodology of that in 2018. In total, 116 sites (of the 588 sites surveyed in 2018) on Hokkaido were surveyed in 2020; there was considerable spatial variation in the declines observed at each locality (trend in parentheses): Sarobetsu (-71%), eastern Soya (-27%), Yufutsu Plain (-39%), Tsurui (-90%), and Nemuro (-28%) (Ura and Tajiri 2020). The principal cause of this reduction has been attributed to extreme drought in Australia, where 50-90% (70% best estimate) of the world population winters (Hansen et al. 2020a).  

However, annual monitoring of c.150 sites in Australia up to November 2021 did not reflect these declines (B. Hansen in litt. 2022) despite Hansen et al. (2020a) suggesting Australian drought as a possible hypothesis for the species' sudden decline in Japan. Moreover, in Sakhalin, the number of Latham's Snipe has remained stable; although numbers dropped slightly in 2020, these had recovered by 2021 and the overall trend over the past three generations is thought to have been stable (P. Ktitorov in litt. 2022). Evaluating and weighting these trends, it is precautionarily suspected that the population declined by 20-29% over the past three generations. Given the threat and cause of this is unexplained and there appears to be inconsistencies, it is unclear whether the decline is continuing or likely to occur in the future.
