Data Zone
Justification of Red List category
This species is suspected to have a small population, comprising a single subpopulation, that is declining within its small range. It is therefore listed as Near Threatened.
Population justification
This species has previously been considered common, being found in Chome Forest Reserve and Mwala Forest, as well as potentially Chambogo Catchment Forest Reserve and Kwizu Forest, and was thought to number several thousand individuals in 1992 (Collar and Stuart 1985). Given the species' restricted range, it is suspected that the population size does not exceed 10,000 mature individuals, and therefore it is placed in the range of 2,500-9,999 mature individuals. This is equivalent to 3,750-15,000 individuals.
Trend justification
Within its restricted range forests are under threat from clearance particularly for agriculture, grazing, and extraction of wood for fuel (BirdLife International 2000). Tree cover loss within the range is currently estimated at 9% across ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein). The population is therefore suspected to be in decline.
This species occurs in the South Pare Mountains, Tanzania.
This species is found in Erica heath, and forest clearings and edge in the South Pare Mountains (BirdLife International 2000).
Forests within its range are under threat from clearance particularly for agriculture, grazing, and extraction of wood for fuel (BirdLife International 2000). Tree cover loss within the range is currently estimated at 9% across ten years (Global Forest Watch 2021, using Hansen et al. [2013] data and methods disclosed therein).
Conservation Actions Underway
Multiple Forest Reserves are found in the South Pare Mountains.
Conservation Actions Proposed
Conduct surveys to get better population size and trend estimates. Forest clearance is rapid in the South Pare Mountains (M. Mills in litt. 2016) and so investigating possible actions that could reduce this forest loss must be imperative.
