This species is listed as Endangered because it has a very small range, within which the total area of its forest habitat is declining owing to clearance for cultivation and intensive charcoal production. Furthermore, the remaining habitat is becoming more fragmented, and the quality of habitat at most sites is declining owing to logging and pole-cutting.

|Range Description:||Anthus sokokensis has been recorded from several sites along the East African coast in Kenya (Bennun and Njoroge 1999, Waiyaki and Bennun 1999, Mlingwa et al. 2000) and Tanzania (Mlingwa 1996), but is extremely rare (and may even be extinct) at some of these. In Kenya, Arabuko-Sokoke Forest has been estimated to support c.13,000 individuals (Musila et al. 2001), but there could now be only c.5,500 individuals in the Brachystegia woodland there (Otieno et al. 2014). |

|Population:||In Kenya, Arabuko-Sokoke Forest has been estimated to support c.13,000 individuals, but this number has now decreased and possibly only c. 5,500 individuals are present in Brachystegia woodland (Otieno et al. 2014). There are no estimates for Tanzanian populations, but the sites where the bird occurs are small, and most are very heavily degraded (N. Burgess in litt. 2007). The total population is therefore placed in the range band for 2,500-9,999 individuals. This equates to 1,667-3,333 mature individuals, rounded here to 1,600-3,400 mature individuals.|
Trend Justification: The population is suspected to be in decline owing to the clearance and degradation of the species's forest habitat, mainly through charcoal burning, agricultural encroachment, logging and pole cutting. The likely rate of decline has not been estimated.
