Species

Justification
Although this species appears to persist in highly degraded habitats, its ecological requirements are poorly known, and habitat loss and degradation on Numfor are on-going. Given that it occurs within a very small range, and is likely to have a small to moderately small, but not severely fragmented population, it is considered to be Near Threatened.

Distribution and population
Tanysiptera carolinae is endemic to the island of Numfor (330 km²) in Geelvink Bay, Papua (formerly Irian Jaya), Indonesia, where it is common and widespread.

Population justification
There is a single subpopulation, restricted to the island of Numfor. The population size has apparently not been quantified.

Trend justification
Data are lacking on population trends, and although this species may be able to persist in degraded habitats, on-going deforestation on Numfor suggests that a slow decline may still be occurring.

Ecology
This species occurs in all lowland habitats on Numfor, including beach vegetation and highly degraded forest (Beehler et al. 1986, D. Gibbs verbally 2000).

Threats
Much of the forest on Numfor has already been destroyed or degraded by logging and subsistence farming (Bishop 1982, K. D. Bishop in litt. 1996).

Conservation actions underway
No protected area currently exists on Numfor, although a reserve has been proposed (Diamond 1986).

Conservation actions proposed
Conduct ecological studies to determine the habitat requirements of this species, and whether it can persist in areas where natural forest habitats are completely removed. Support plans to establish a nature reserve on Numfor.
