Justification
EOO 189 km², known from six severely fragmented subpopulations. Over 95% of its habitat has been transformed for wheat cultivation. Occurs in small, isolated fragments of renosterveld on south-facing slopes between wheat lands. One subpopulation has experienced severe decline (over 90% of mature individuals lost) due to too frequent fire. The remnant is burnt with surrounding wheat stubble annually after the harvest in November. Frequent fire, coupled with livestock grazing, is causing continuing declines at most of the remaining subpopulations.
