Taxonomic note
Lophura edwardsi (del Hoyo and Collar 2014) was previously split as L. edwardsi and L. hatinhensis following Sibley and Monroe (1990, 1993). Lophura imperialis (Sibley and Monroe 1990, 1993) is considered a hybrid between Silver Pheasant Lophura nycthemera and Edwards's Pheasant L. edwardsi following Rasmussen (1998), Garson (2001) and BirdLife International (2001).

Population justification: The complete lack of records since 2000 suggests that any remaining wild population is now tiny (S. Mahood in litt. 2012), and it has even been suggested that the species may already be extinct in the wild. The captive population numbers more than 1,000 individuals. In the absence of better data, the population is placed here in the band 50-249 mature individuals. Any remaining subpopulations are likely to be extremely small and declining.

Trend justification: The species is suspected to be declining rapidly from a combination of hunting and habitat loss, given that virtually all forest habitat within its range has now been lost and remaining fragments are under intense pressure.
