This pheasant is classified as Vulnerable because it is suspected to be declining rapidly owing to extensive and on-going habitat loss, compounded by hunting. It is also assumed to have a small population, which is likely to be experiencing increasingly severe fragmentation, particularly as it may be dependent on nomadic visits to lowland areas.

|Range Description:||Lophura bulweri is endemic to Borneo, where it is known from Sabah and Sarawak, Malaysia, Kalimantan, Indonesia and Brunei. Although apparently rather patchily distributed, it was once described as very common in undisturbed parts of interior Borneo. In 1995, it was estimated to number fewer than 10,000 individuals. Despite there being no reason to believe that the species was threatened a decade ago, the paucity of recent records, combined with anecdotal information regarding its habits and alarming current rates of habitat loss, indicate that it may be declining rapidly. |

|Population:||The population is estimated to number 1,000-10,000 individuals by McGowan and Garson (1995). It is placed in the band 2,500-9,999 mature individuals here, equating to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
Trend Justification: The species is suspected to be undergoing a rapid population decline owing to the loss and fragmentation of its forest habitat, although it is mainly restricted to relatively less threatened hill forest, with the possibility that the rate of decline is slower than this (B. van Balen in litt. 2012), necessitating further research.
