Justification | This species formerly occurred on the Cape Flats, but >80% of known subpopulations in this area are now locally extinct due to habitat loss to crop cultivation and urban expansion over the past 60 years (generation length 20 years). Recent surveys located only four locations between the Cape Peninsula and Struisbaai, but two of these have been lost to coastal development since 2002, resulting in a 25% decline in the population in less than one generation. Two small, severely fragmented subpopulations remain, one at Cape Point consisting of less than 50 plants, the other near Struisbaai has ± 80 plants. AOO<10 km², and habitat loss continues due to alien plant invasion and ongoing coastal development. |
