The present status of vegetation conservation in South Africa J. C . S C H E E P E R S *

A B ST RA C T Progress with the conservation of representative stands of the great variety of South African ecosystems, as represented by vegetation types, is reviewed against progress towards better co-ordinated and national planning of the various conservation activities pursued by different conservation authorities.

RESUME LE STATUT ACTUEL DE LA CONSERVATION DE LA VEGETATION EN AFRIQUE DU SUD Les progrês obtenus dans la conservation de zones représentatives de la grande variété d'écosystêmes sud-africains, tels qu'ils sont représentés par des types de végétation, sont examinés en les comparant avec ceux réalisés pour établir un programme á l'échelle nationale et mieux coordonné des diverses activités ,de conservation poursuivies par différentes autorités responsables.
