Poaching continues, with at least 100 black rhinos killed in Zimbabwe during 1991 and the white rhino populations in Swaziland being decimated.
The slowing in the rate of decline in the black rhinoceros can be explained simply by there being fewer soft targets, but the populations in many countries have been depleted to dangerously low levels. Less than half the 14 countries with black rhino populations have more than 50 rhinos, and only one of the three subspecies, namely D.b. minor, numbers more than, or anything close to, the minimum recommended figure of 2,000 animals required for genetic viability.

The trend is towards small, well-protected and managed 'sanctuaries' as found in South Africa and Kenya, and which are now being adopted elsewhere. Such areas provide sound investment opportunities for funding agencies.
