This week's programme in the series on Man and Science today

After its first transmission, this programme was described by Sean Day-Lewis of the Daily Telegraph as 'without qualification the best wildlife film made for television I have seen.'
It concerns itself with managing wildlife in Africa - wildlife so profuse, so breathtakingly beautiful that the idea of 'managing' it, of organising its survival in the midst of our encroaching world can seem unnecessary, even insolent.
And yet it must be done. In our own lifetime the great game herds have been decimated and the balance between species has been disrupted. If a new balance is to be achieved man must create it, but the comprehensive wildlife policy needed for this must be based on more than the legends of white hunters.
For this programme Horizon visited the Scientific Research Institute in the Serengeti National Park in Tanzania, where scientists are plotting the intricate patterns of wildlife behaviour. It's this background information that's vital before animal conservation can be put on a proper systematic basis.
