This species qualifies as Vulnerable because its population is likely to be small and in decline owing to the loss and degradation of its montane woodland habitat.
Turdus menachensis is endemic to the south-western Arabian peninsula, occurring in Saudi Arabia and Yemen, north to 21°N (Bowden 1987). It is strictly montane (Porter et al. 1996) and has a very local distribution, being generally scarce (Bowden 1987) where it occurs (although occasionally numerous in some areas [Stagg 1984, Jennings et al. 1988, Newton and Newton 1996]). Given that so much of its range contains unsuitable habitat, its population seems likely to number fewer than 10,000 mature individuals. However, the population has been estimated at c.10,000 pairs (Jennings 2010), implying that there is a population of c.20,000 adults (M. Jennings in litt. 2012), thus the population estimate used in this assessment may need to be revised.

|Population:||The population is estimated to number 2,500-9,999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 3,750-14,999 individuals, rounded here to 3,500-15,000 individuals.|
|Habitat and Ecology:||It is confined to areas with a dense cover of native trees and shrubs - thus occurring in woodlands, thickets, copses, orchards and large gardens, although foraging in more open habitats if dense wooded cover is nearby (Stagg 1984, Bowden 1987, Jennings et al. 1988, Newton and Newton 1996, Porter et al. 1996). At the lowest altitudes, it is restricted to such vegetation along watercourses. At most localities it appears to be sedentary, but there may be altitudinal or latitudinal movements in the north of its range (Stagg 1984). The diet includes fruit (e.g. Rosa, Juniperus, Ficus) and terrestrial invertebrates (Phillips 1982, Bowden 1987). Breeding occurs from March to June, the nest being 1-2 m above ground in a bush or tree-fork, usually in dense cover (Bowden 1987).|
Lopping and cutting of trees and shrubs, for fuel, fodder and building material, are proceeding at unsustainable levels in many parts of Yemen (Bowden 1987, Scholte et al. 1991) (where the human population is expanding rapidly), and are likely therefore to be causing a net loss of dense wooded cover. Abandonment of wooded agricultural terraces at lower altitudes in the species's range is leading to massive loss of topsoil and further reduction of wooded cover (Scholte et al. 1991). Loss of well-wooded land to building, infrastructural and agricultural developments may also be a threat in Saudi Arabia. Altogether, these threats imply that the species's population is likely to be decreasing. A lack of tree regeneration, owing to high levels of grazing and browsing by livestock, has been observed at several sites and may be a problem.
Conservation Actions Underway
There are many traditional rangeland reserves (mahjur) in south-west Arabia, where trees and ground plant cover are protected by private or communal ownership-rights from excessive exploitation, in order to provide fodder in times of drought (Scholte et al. 1991). However, the management of these areas has been widely neglected or abandoned since the advent of more convenient supplies of supplemental feed (Scholte et al. 1991). The species occurs in at least two protected areas in Saudi Arabia: Raydah Reserve and Asir National Park (Jennings et al. 1988, Newton and Newton 1996). Conservation Actions Proposed
Encourage non-intensive agroforestry practices. Conduct field surveys to estimate its population size. Study the effects of different forestry practices on species density and breeding success.
