Range DescriptionPolyplectron katsumatae is endemic to the island of Hainan, China (del Hoyo et al. 1994, Madge and McGowan 2002, Chang et al. 2008, Collar 2009). As a result of habitat loss and hunting, both its range and population have dramatically declined since the 1950s, with the remaining population fragmented into small, partially isolated subpopulations (Chang et al. 2008). The total population was estimated at 2,700 individuals in 1990, and at only 300 individuals in 2000 (Chang et al. 2008). Although the latter is probably an underestimate of the true population size, the population is likely to have declined rapidly owing to habitat loss and hunting (Liang Wei in litt. 2010, Zhang Zhengwang in litt. 2010).
