It was founded in 1966 out of a mutual desire within the zoo community to see sound principles and practices of animal management widely adopted in the British Isles. Today, the Zoo Federation is the principal, professional zoo body representing the responsible zoo community in the UK and Ireland. The Zoo Federation Research Group (ZFRG) operates under the auspices of the Zoo Federation's Conservation and Animal Management Committee and supports basic and applied research of relevance to both in situ and ex situ conservation, welfare and other zoo-related topics. Every year the group holds a symposium on zoo research to promote scientific
