Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International

Justification:
This species has a moderately small range in which logging is intensifying. Since it is fairly intolerant of degraded forest it qualifies as Near Threatened. However, some of the races which occur on very small islands may be very much more threatened.

Geographic Range [top]

Range Description: Monarcha browni is endemic to the New Georgia group of islands in the Solomon Islands. It is a low-density forest species with a small total population, described as "rather uncommon" (Dutson 2011). It occurs as four quite distinct races, some of which are single island endemics. In particular the distinct subspecies ganongae on Ranongga (where there is little remaining forest), and nigrotectus on Vella Lavella (where logging is extensive) and Bangga, are naturally scarce and therefore highly threatened (Gibbs 1996, G. Dutson pers. obs. 1998, Hornbuckle 1999, Dutson 2011).

Population [top]

Population: The global population size has not been quantified, but the species is described as common or fairly common. Race nigrotectus is described as uncommon and race ganongae is described as rare (del Hoyo et al. 2006).
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is a primary forest species, rarely found in degraded forest habitats, to a maximum of 600 m.

Systems: Terrestrial

Threats [top]

Major Threat(s): Widespread logging across the area is causing a decline, but it has strongholds in forest reserves on Kolombangara and unlogged areas on other islands (Blaber 1990, Buckingham et al. 1995, G. Dutson pers. obs. 1998, Hornbuckle 1999) and does not yet have a fragmented distribution. Any significant increase in the areas being logged on these islands could render the species threatened.

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
None is known.

Conservation Actions Proposed
Regularly monitor the populations of all races at selected sites. Research its tolerance of degraded forest. Protect significant areas of remaining primary forest from logging on all islands where it occurs. Fully investigate the taxonomic status of the four races.
