Unfortunately the followup was getting zoos to maintain, become members of the International Union for the Conservation of Nature. The followup wasn’t there on the part of the IUCN at the time. And while I had considerable influence in the council of the IUCN, I also had a very odd perspective. I wasn’t on the program committee. I was on the administration committee for the IUCN. And there were some tough ethical questions, because my institution had a larger budget than the International Union for the Conservation of Nature, which consists of government members from around the world as well as non-governmental members. So getting the zoos to take advantage of the, especially the volunteer commissions on national parks and protected areas, and on the species survival front, was a bit challenging, a bit difficult. But one of my real accomplishments was challenging the International Union of Directors of Zoological Gardens to come aboard in a substantial way.
