This little-known species is only known from one location, qualifying it as Vulnerable. If it proves to be declining, for instance through agricultural conversion of its naturally scarce and fragmented habitat, then it would be reclassified as Critically Endangered, but further research may show it to occur at other sites in this very poorly known area.

|Range Description:||Lonchura vana is endemic to the Arfak Mountains in the Vogelkop Peninsula in north-west Papua (formerly Irian Jaya), Indonesia (Hoogerwerf 1971, Beehler et al. 1986). It is poorly known, but could be restricted to a single location - grasslands around the lake Anggi Gigi (D. Gibbs in litt. 2000). Other reports that it occurs elsewhere in the Arfaks, such as the Tamrau Mountains (Hoogerwerf 1971, Beehler et al. 1986) appear to be unsubstantiated, and there are no records from around the neighbouring lake, Anggi Gite. Its possible occurrence elsewhere is limited by the scarcity of its habitat (N. Bostock in litt. 1993, D. Gibbs in litt. 1994). However, the Arfaks have not been well-explored and it may prove to occur elsewhere (K. D. Bishop in litt. 2000). |

|Population:||The global population is estimated to number no more than 10,000 individuals, and so it is placed in the band 2,500-9,999 individuals. This equates to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 mature individuals.|
Trend Justification: There is insufficient information to infer population trends for this species. However, there is no evidence of any factors currently threatening the population, so it is suspected to be stable.
