This species is classified as Near Threatened because it is thought to be undergoing a moderately rapid population reduction, as a result of habitat destruction. Rates of forest loss warrant monitoring within its range, were they to increase significantly it may warrant uplisting to Vulnerable.
|Previously published Red List assessments:|
|Range Description:||Rhipidura tenebrosa is endemic to Makira (= San Cristobal) in the Solomon Islands where it is relatively uncommon and restricted to closed-canopy forest (Cain and Galbraith 1956, Buckingham et al. 1995, Hornbuckle 1999, Dutson 2011).|

|Population:||The global population size has not been quantified, but the species is described as relatively uncommon and little known (del Hoyo et al. 2006).|
Trend Justification: There are no data on population trends; however, the species is suspected to be in slow to moderate decline owing to on-going habitat degradation.
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||It is restricted to closed-canopy lowland forest, to a maximum of 700 m. Commonest in hills (Dutson 2011). |
|Continuing decline in area, extent and/or quality of habitat:||Yes|
|Generation Length (years):||4.9|
|Movement patterns:||Not a Migrant|
|Major Threat(s):||The lowlands of Makira are largely logged or under logging concessions. It is far less common in logged forest and further research may show it have a small total population which is in decline or to be threatened by logging (G. Dutson pers. obs. 1998, R. James in litt. 1999).|
Conservation Actions Underway
None is known. Conservation Actions Proposed
Conduct surveys to determine population trends. Determine habitat requirements and susceptibility to logging. Ascertain area of forest and rates of clearance across the island. Monitor numbers at sites across the island. Ensure protection of significant areas of lowland forest on Makira.
