The Jackson Zoo resigned its accreditation with the American Zoological Society last Friday. The AZA confirmed the Zoo's resignation and its website reflects the change.
Update (4:28 PM): The Jackson Zoo issued the following press release:
The Board of Directors of the Jackson Zoological Society voted unanimously to resign its membership in the Association of Zoos and Aquariums (AZA), sending a resignation letter on Friday, August the 19th. Zoo staff, with the support of the Board, will work over the next two-three years to identify a funding structure that supports its recently completed facility master plan and strengthen its organizational and financial model. The Zoo anticipates that it will re-apply to be a member of the AZA once the integrated funding, organizational and financials models are in place.
Kingfish note: Jackson Zoo Director Beth Poff confirmed the resignation also and said a press release will be issued later today.
