Year Published: 2016
Date Assessed: 2016-10-01

This poorly known and apparently highly localised species is thought to have a moderately small population which may be declining owing to habitat loss; it is therefore classified as Near Threatened. If it was found to be more numerous than currently known it may be downlisted.

Population [top]

Population:Population numbers are not known.

Trend Justification:  There are no data on population trends, but this species is suspected to be in decline owing to habitat loss.
Current Population Trend:Decreasing
Additional data:
Continuing decline of mature individuals:Yes
Extreme fluctuations:NoPopulation severely fragmented:No
Continuing decline in subpopulations:Unknown
Extreme fluctuations in subpopulations:NoAll individuals in one subpopulation:No

Habitat and Ecology [top]

Habitat and Ecology:It inhabits high altitude forests, often with Pandanus on high frost-disturbed plateaus from 2,300-3,660 m, and rarely as low as 1,750 m (Beehler et al. 1986, Coates 1990). Has a clutch size of one (Donaghey 2015). Often seen individually or as mother-offspring pairs. Male bowers have two structural components, the first being a matted fern stage covered in snail shells and other small objects, and the second being low branches over the stage covered in epiphytic orchids (Pratt and Beehler 2015).

Continuing decline in area, extent and/or quality of habitat:Yes
Generation Length (years):9.2
Movement patterns:Not a Migrant

Threats [top]

Major Threat(s): Subpopulation sizes and inter-site dispersal is unknown; it may be at risk of population fragmentation (A. Mack in litt. 1999). It is threatened by logging on two mountains in its tiny range of only c.800 km2 in Papua New Guinea (Beehler 1985, Collar 1986), but the larger Papuan populations are judged to be safe.

None is known.

Conservation Actions Proposed
Monitor populations in the locations where it is known to occur. Survey to discover additional populations. Protect forest at sites where it occurs.
