This species is known only from few localities in New Guinea, with the only records being from nine sites in the 1980s and 1990s. The population size is unknown and it is described as apparently very scarce or rare. There is no information on its likely distribution extent, population trends, or threats, although it is potentially threatened by logging of lowland forests. For these reasons, it is classified as Data Deficient.

|Range Description:||Uroglaux dimorpha is sparsely distributed in New Guinea (Papua, formerly Irian Jaya, Indonesia and Papua New Guinea), known only from few localities in the north-west, including Yapen island, near Vanimo and Lae, the south-east and Gulf Province (Coates 1985, Beehler et al. 1986, Lamonthe 1993). There are only records from nine sites in the 1980s and 1990s, including a series of birds captured near Lae (Hicks 1988, Lamonthe 1993, Shany 1995, K. D. Bishop in litt. 1999, P. Gregory in litt. 1999, T. Leary in litt. 2000, C. Makamet per B. Beehler in litt. 2000).|

|Population:||The global population size has not been quantified, but the species is described as apparently very scarce or rare (Konig et al. 1999).
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
|Current Population Trend:||Stable|
|Habitat and Ecology:||It is a lowland forest species, occasionally recorded to 1,500 m, and is also found in gallery forest in savannah (Coates 1985).|
|Continuing decline in area, extent and/or quality of habitat:||Unknown|
|Generation Length (years):||5.4|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||Its tolerance of degraded habitat is unknown and it is potentially threatened by logging of lowland forests.|
Conservation Actions Underway
CITES Appendix II. Conservation Actions Proposed
Survey historical locations and potentially suitable habitats for the species. Study its ecological requirements, tolerance of habitat degradation and threats.
