Restoring the biodiversity of the Roggeveld-Renosterveld:evaluation,multiplication and establishment of indigenous plant species on old agricultural fields
Introduction The Hantam-Roggeveld in the Northern Cape Province of South Africa,which stretches over 300 km2 was identified by Succulent Karoo Ecosystem Programme ( SKEP ) as a priority area for conservation.Priorities include multiplication of seed indigenous to the Roggeveld to improve and restore biodiversity.The botanical biodiversity of the area has in the past been negatively impacted by crop production resulting in huge areas which now lay fallow and exposed to erosion due to poor vegetation cover.The objectives of this project are to increase our understanding and knowledge of six key plant species found in the Roggeveld and their use in rangeland restoration,as well as to create awareness among the local farmers on the necessity to actively restore and manage old agricultural fields.Wild rye ( Secale af ricanum) is a very palatable forage plant and endemic to the Hantam-Roggeveld.It has become critically endangered due to poor livestock management practices.It now occurs in very small populations on only two farms within the area and is the flagship species for this project.
