I have a somewhat noobish question that I'm sure some of the more experienced members of the forum can answer. I've been lurking on here for a month now, and I'm really enjoying reading all the arguments past and present. I made a list of all the UK zoos I wanted to visit a while back and I'm working my way through it. I made the assumption that zoos that were not members of BIAZA were not worth visiting, or even should not be visited. It's clear that there are some collections that are not members that are really popular with zoochatters, like the Aspinall parks, Cotswold, Hamerton and RSCC, and everything I've read makes me think these are excellent zoos. Is it a politics thing or are there other reasons why a zoo would not be part of BIAZA? Thanks in advance.
