The CEI has been involved with the protection and reintroduction of North American bison and trumpeter swans (in partnership with the Canadian Wildlife Service), founding the first captive-breeding colony of swift fox intended solely for reintroduction (1972), initiating the Canadian swift fox reintroduction programme (1978 – 1997) and the first swift fox reintroduction in the USA (1998-2002). The CEI has also founded an international Cetacean survey WhaleForce (est. 1986 –ongoing). Upon request, the CEI has provided captive management evaluations (eg. 2002, S.S. Waters, An Evaluation of Five Zoos in Indonesia, WSPA, 2001, C. Smeeton, Husbandry Notebook, 2nd Edition North American river otter, AZA small carnivore TAG).
