Population justification: The global population has not been quantified, but was estimated as probably 'in tens of thousands' by Ferguson-Lees and Christie (2001). The population in South Africa, Lesotho and Eswatini is believed to be c.800 pairs (Taylor 2015); the population in Namibia is estimated at <350 pairs (Simmons 2015). In Ethiopia, raptor road-count surveys between 2010-2017 had a Martial Eagle observation rate of 0.00055 individuals/km (E. Buechley in litt. 2020). Martial Eagles are still widespread and frequently observed in Malawi (S. Chihana in litt. 2020), and Tanzania (N. Baker in litt. 2020).

Trend justification: Declines have taken place across much of this species's range owing to habitat loss, deliberate and incidental poisoning, collisions with power lines, and pollution. Surveys across Mali, Burkina Faso and Niger detected a reduction in the observation rate in unprotected areas from 0.8 to 0 birds/100 km, and a reduction in the observation rate in National Parks from 1.4 to 0.7 birds/100 km (Thiollay, 2006). These rates of reduction are equivalent to a 100% reduction in unprotected areas and a 51% reduction in National Parks when scaled across three generations. Similarly in Botswana, Garbet et al., (2018) reported a reduction in observation rates from 0.14 to 0.09 birds/100 km, which after controlling for variations in transect survey lengths and distributions equates to a rate of decline of 67% over three generations. In Kenya, surveys detected a 65% reduction in the observation rate in unprotected areas (from 0.23 to 0.08 birds/100 km) and a 133% increase in the observation rate in protected areas (from 0.53 to 1.24 birds/100 km; Ogada et al., in prep. a). These rates of reduction would equate to a 58% reduction in unprotected areas and a 102% increase in protected areas over three generations. Analysis of reporting rates for South Africa from the Southern African Bird Atlas Project (SABAP) 1 (1987–1992) and SABAP 2 (2007–2012) also found a 59% reduction in mean reporting rate (from 7.3% in SABAP 1 to 3.0% in SABAP 2; Amar & Cloete, 2018). Scaled across three generations, this rate of change would equate to a reduction of 77%. The overall rate of decline is difficult to quantify but is suspected to have been very rapid over the past three generations (33 years). It is consequently placed in the band 50-79%.
