It was the time I was a registrar. And there was a reason to start an international step book. Because at that time, zoos still usually imported wild code specimens. And the reasoning for starting the studbook was to reach a self-sustaining population of vicunas that can act as ambassador for saving the vicunas in the wild because vicuna have the finest wool of any animal and that was reasons they were shot poisoned in the wild. And therefore a campaign for saving vicunas in the wild was a very positive part zoos could play in these days.
