Population justification: The total range appears to be a single grassland patch just 30-36 km2 in area, and its population density is an order of magnitude lower than previously suspected, inferring a global population of 90-256 mature individuals, roughly equivalent to 130-390 individuals in total. |
Trend justification: The population is suspected to be declining because the species is restricted to grassland in the calcareous plateau east and south of Negele (L. Borghesio in litt. 2005) which decreased in area by about 30% between 1973 and 2002, and is being rapidly encroached by shrubs, agriculture and homesteads. The remaining area is being rapidly degraded due to overgrazing by livestock. Over 15% of remaining habitat on the Liben plain was lost in a single year, suggesting that the rate of decline may now be higher (P. F. Donald in litt. 2012).
