The survey was hailed as probably the most
comprehensive national survey, worldwide.
Its contents indicated that South Africa can
hold its head up when it comes to e ective
wildlife management.
The 10 critically endangered species include
one of our three sub-species of the black
rhinoceros. The black rhino population as a
whole is holding steady in South Africa. At last
count they probably numbered 700, of which
230 were in Kruger Park and 463 in Zululand
(Hluhluwe/Umfolozi and Mkuzi).
The ‘Red List’ of the IUCN (International Union
for the Conservation of Nature) deemed the
black rhino to be ‘critically endangered’ in
its global context. But the EWT’s Red Data
Book showed it is, in fact, increasing in this
country and in our national context can be
rated as ‘vulnerable’ - two categories more
optimistic than ‘CE’.
Fifty years ago, the white rhinoceros would
have been deemed ‘critically endangered’,
just like the black. Only a few score were left,
nearly all of them in Zululand. Zululand’s
e orts in the mid-century to protect the Forest-dwelling samango – now 'endangered'
white rhino brought numbers up into the
thousands. The campaign, probably the most mountain zebra, one of two sub-species of Africa there are fewer than 2 500 of which

might not excite public interest, but their
loss should concern us because any loss of
a species reduces biodiversity and therefore
threatens the whole.
South Africa has not, as far as is known, had
a species extinction for well over a century. It
is possible that some smaller species might
have been extinguished before they were
even discovered. Look at the various kinds of
