Faced with the problem of having to capture large numbers of game animals on difficult terrain and in a short time, the author, who is Senior Capture Officer of the Natal Parks Board in South Africa, hit on a remarkably simple and highly successful method. He found that large animals like antelopes will not attempt to go through or past plastic material, and by making a cheap and simple plastic ‘curtain’ he could drive them with a helicopter into waiting lorries. This way he captured 3500 animals in four months.
