NT
Ribbon-tailed Astrapia Astrapia mayeri



Justification

Justification of Red List Category
This species is likely to have a moderately small population within its small range. It is likely to be declining owing to ongoing habitat degradation, but the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

Population justification
The population size of this species has not been quantified, but it is described as fairly common to locally abundant.

Trend justification
There are no data on population trends; however, the species is thought to be in slow decline, owing to on-going habitat degradation.

Distribution and population

Astrapia mayeri has a small range in the central mountains of Papua New Guinea, from the Strickland River to Mt Hagen and Mt Giluwe, c.130 km west. Its western limits require further surveying. It is generally fairly common, even in degraded forest. At a new site, Kumul Lodge in the west of its range, it is reported to be abundant (Salvadori 1998).

Ecology

It occurs in montane forest between 2,400 and 3,400 m, sometimes down to 1,800 m and also in degraded forest.

Threats

It is locally threatened by hunting for tail plumes and by large-scale logging and forest degradation but it is safe in the inaccessible portions of its range (Coates 1990, P. Gregory in litt. 1994, Frith and Beehler 1998). Previous concerns of genetic swamping through hybridisation with Stephanie's Astapia A. stephaniae in the far east of its range are now discounted.

Conservation actions

Conservation Actions Underway
CITES Appendix II.

Conservation Actions Proposed
Regularly monitor the populations at selected sites. Further research its tolerance of degraded forest across an altitudinal gradient. Protect significant areas of remaining primary forest.
