Population justification: Surveys of the species conducted between 1999 and 2008 provide an estimate of 8,675 individuals, rounded to c.9,000 individuals in total on Socotra (Porter and Suleiman 2013, R. Porter in litt. 2016). This is equivalent to c.6,000 mature individuals.
Trend justification: There is no evidence for recent or current population declines, and the species' population trend has apparently remained stable since detailed surveys were initiated in 1999 (Jennings 2010).
