Captain Keith Caldwell, in his admirable report of a faunal survey in Eastern and Central Africa conducted in 1947, says: “… Were one of the old hunters who operated fifty years ago to visit Eastern Africa to-day, he would find vast districts in which he used to shoot completely denuded of game; in fact, it is probable that the game areas have been reduced by half, and the game within many of those left by 75 per cent.”

That, I think, is a fair estimate: a reduction of the fauna of Eastern and Central Africa to between a half and one-quarter of what it was half a century ago. The same applies more or less, but mostly more, to the whole of Africa south of the Sahara. The question before us now is what will be the state of this unique assemblage of fauna, including many species found nowhere else in the world, at the end of the next half-century?
