Justification
Aloe falcata is a widespread and common species. In spite of some historical decline due to succulent collecting and overgrazing, it is not in danger of extinction.
Distribution
Endemism
South African endemic
Provincial distribution
Northern Cape, Western Cape
Range
This species is widespread across Namaqualand and the Richtersveld in north-western South Africa, from the lower Gariep Valley to Klawer and the northern Roggeveld Escarpment near Calvinia.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Succulent Karoo
Description
It occurs on dry sandy flats in succulent karoo.
Threats
Hilton-Taylor (1996) listed A. falcata as vulnerable. Van Wyk and Smith (1996) also consider the species vulnerable (possibly following Hilton-Taylor) due to illegal collection of wild plants and habitat degradation due to overgrazing. According to E. van Jaarsveld (pers. comm.), this species is neither vulnerable nor rare, and there are many subpopulations in good condition around Calvinia and in Namaqualand. As the species was found to be more common and widespread than previously thought, Van Wyk and Smith (2003) considers it not threatened.
