Justification | Secale strictum subsp. africanum is a range-restricted taxon that was once common on the Roggeveld, but is now known from one subpopulation on a farm, where there are fewer than 50 mature individuals. This taxon has experienced severe declines due to overgrazing and poor veld management. It is cultivated and since 2003 several attempts have been made to reintroduce it to other properties on the Roggeveld, however none have been documented to be successful. It is listed as Critically Endangered under criterion D. |

Population |
It was once common on the Roggeveld Plateau and the name of the region comes from this grass. However livestock overgrazing, bad veld management has caused the majority of the population to be lost. There is only one remaining stand of this species which has fewer than 50 plants. The landowner has fenced off the remaining population to ensure that it is not grazed by livestock. The population has remained stable between 2007 and 2022.
