Justification This spectacular and unique partridge is fairly widespread accross the Sundaic lowlands where it is not uncommon, however logging has been intense throughout that region and it is likely to have underone a moderately rapid population reduction. It consequently is classified as Near Threatened.

Range & population Rollulus rouloul is confined to the Sundaic lowlands, where it is known from south Tenasserim, Myanmar, peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Brunei and Kalimantan and Sumatra, Indonesia. The species remains common in several areas, is able to persist in selectively logged forest and can utilise early-stage regenerating forest, and although it has undoubtedly declined, it is likely to be secure at present.

Ecology: It occurs in broadleaved evergreen and dense primary lowland and hill forests and bamboo up to 1,550 m.

Threats Forest destruction in the Sundaic lowlands of Indonesia and Malaysia has been extensive (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998), and declines are compounded by trapping for the cage-bird industry. However, the species's use of secondary growth and higher elevations implies that it is not immediately threatened.

Conservation measures underway It occurs in a number of protected areas.

Conservation measures proposed Survey to assess the size of the population. Regularly monitor the population at selected sites. Asses the effect of hunting on populations. Protect large areas of forest in areas where it occurs.
