The Honolulu Zoo’s accreditation has been renewed after exhibit upgrades, more staffing and new signage were put in place in response to the Association of Zoos and Aquariums deferring renewal a year ago because standards were not being met.

"This renewal affirms that the Hono­lulu Zoo is meeting, and I would say right now exceeding, all of those standards," said Mayor Peter Carlisle at a news conference held Monday at the zoo’s entrance. "A high bar has been set, and we plan to maintain it."

In March 2011 inspectors raised concerns over the size of the exhibit for two female Asian elephants, Mari and Vai­gai, after an inspection was conducted two months earlier. The survey took place before a new 1.5-acre elephant exhibit opened in December.

A follow-up inspection was conducted in January.

"The new exhibit helped tremendously in addressing that particular deficiency," zoo director Manuel Mol­li­nedo said.

Officials also filled vacancies for a reptile curator and a second veterinarian. Additional staff was hired for the elephant exhibit as well as grounds maintenance. Directional signage and informational graphics also were installed at the zoo.

The reaccreditation is for four years. "The latest upgrades and improvements will help our zoo remain a vibrant, world-class facility so our residents and visitors can continue to enjoy its animal collection," said Carlisle.
