indistinguishable (R. Sözer in litt.), but females show<br />

distinct morphological differences (Chasen <strong>and</strong><br />

Hoogerwerf 1941).<br />

Range <strong>and</strong> population: The Sumatran pheasant is endemic<br />

to northern Sumatra, Indonesia, where it is known<br />

historically by two females (both collected) <strong>and</strong> one male<br />

(glimpsed) in the Gayo Highl<strong>and</strong>s, Aceh Province, within<br />

what is now the Gunung Leuser National Park (Chasen<br />

<strong>and</strong> Hoogerwerf 1941). In 1979, there were several sightings<br />

of family parties in the Mamas Valley of this park (van<br />

Marle <strong>and</strong> Voous 1988) <strong>and</strong>, in 1998, a female was observed<br />

above the River Jagong in the Beutong region just north<br />

of the Leuser ecosystem (B. Long in litt.). In 1998–99, five<br />

individuals of each sex were recovered from a bird market<br />

in Medan, north Sumatra. All are said to have originated<br />

from Gunung Leuser (R. Sözer in litt.). There are no<br />

published population estimates, but an ongoing<br />

contraction of suitable forest habitat must be having an<br />

adverse effect. There are currently three pairs (of wild<br />

origin) in captivity on Java.<br />

Ecology: The first specimen was shot in the forest<br />

(reasonably assumed to be tropical, lower montane<br />

rainforest) adjacent to the mountain lake Telaga Meluwak<br />

at 1,200–1,400m, the general area being described as “hilly<br />

ground covered with heavy primary jungle, but with little<br />

undergrowth”. The other female was collected at 600m<br />

(Meyer de Schauensee <strong>and</strong> Ripley 1940). The observations<br />

in the Mamas Valley were of birds feeding on the rather<br />

bare, open forest floor on relatively dry mountain slopes<br />

at 1,200–2,000m (van Marle <strong>and</strong> Voous 1988).<br />

Threats: Apparently, suitable habitat within its putative<br />

range has been reduced <strong>and</strong> fragmented below about<br />

1,000–1,500m, owing to agricultural encroachment, largescale<br />

timber extraction, <strong>and</strong> the attendant risk of wildfires,<br />

even within Gunung Leuser National Park (D.A. Holmes<br />

in litt.). Hunting, presumably, also poses a threat, given<br />

the recent discovery of the species in an urban market in<br />

north Sumatra.<br />

<strong>Conservation</strong>: All the known localities fall within the<br />

Gunung Leuser National Park, which embraces 9,460km 2<br />

of habitat from sea-level to almost 3,500m.<br />

Targets:<br />

• Conduct extensive surveys in Gunung Leuser National<br />

Park <strong>and</strong> adjacent regions (e.g., the Batak Highl<strong>and</strong>s) to<br />

establish the species’ range, altitudinal distribution, <strong>and</strong><br />

habitat requirements.<br />

• Press for the control of illegal tree-felling in Gunung<br />

Leuser National Park, in particular.<br />

• Clarify its taxonomic relationship with the Salvadori’s<br />

pheasant using DNA sequencing techniques.<br />

• Advocate full protection for the species under Indonesian<br />

law.<br />

Salvadori’s pheasant<br />

(Lophura inornata)<br />

Vulnerable C1; C2a<br />

This pheasant qualifies as Vulnerable. There are few records,<br />

indicating that it has a small population, which is declining<br />

<strong>and</strong> becoming fragmented owing to clearance of mid-altitude<br />

forests.<br />

Taxonomy: The Salvadori’s pheasant is sometimes<br />

considered conspecific with the Sumatran pheasant<br />

(Delacour 1977). The males are apparently morphologically<br />

indistinguishable (R. Sözer in litt.). However, females show<br />

distinct morphological differences (Chasen <strong>and</strong> Hoogerwerf<br />

1941).<br />

Range <strong>and</strong> population: The Salvadori’s pheasant is endemic<br />

to Sumatra, Indonesia, where it is known from at least 10<br />

localities in the central <strong>and</strong> southern Barisan mountain<br />

ranges. There are recent records from at least two of these<br />

sites, Gunung Kaba <strong>and</strong> Gunung Kerinci, both within<br />

Kerinci-Seblat National Park (Holmes 1989, 1996). It was<br />

described as fairly common around Kerinci in the early<br />

1900s (Lambert <strong>and</strong> Howes 1989, Holden 1997).<br />

Ecology: It is a resident of lower (<strong>and</strong> possibly upper)<br />

montane rainforest from about 800–2,200m, with most<br />

observations coming from above 1,000m. It appears to<br />

prefer primary, unlogged forest, but also frequents<br />

disturbed <strong>and</strong> degraded habitats in close proximity to<br />

primary forest (Lambert <strong>and</strong> Howes 1989, Holden 1997).<br />

Threats: In Kerinci-Seblat National Park, the species is<br />

declining due to heavy trapping by local people for food<br />

(Holden 1997). Much of the forest within the lower part of<br />

the species’ altitudinal range around Kerinci has already<br />

been cleared for shifting cultivation, <strong>and</strong> is vulnerable to<br />

further illegal agricultural encroachment <strong>and</strong> increasingly<br />

frequent drought fires (D.A. Holmes in litt.).<br />

<strong>Conservation</strong>: The species is known to occur in at least one<br />

large protected area, the Kerinci-Seblat National Park,<br />

plus two other areas currently designated as protection<br />

forest, but proposed for upgrading to wildlife reserves,<br />

Gunung Singgalang <strong>and</strong> Bukit Dingin/Gunung Dempu.<br />

Targets:<br />

• Conduct surveys to establish its range, distribution, <strong>and</strong><br />

habitat requirements, particularly within Kerinci-Seblat<br />

National Park.<br />
