Consistently ranked as one of the world's top five zoos, Omaha's Henry Doorly Zoo and Aquarium is an independent not-for-profit organization accredited by the Association of Zoos and Aquariums.

As a leader in conservation, the Zoo focuses on areas to benefit animal husbandry and species conservation. Focus areas include conservation genetics, conservation medicine, rare plant conservation, reproductive sciences and comparative nutrition. The Zoo is recognized nationally for its conservation, animal care and exhibit design.

Omaha’s Henry Doorly Zoo and Aquarium has partnered with Dr. Andrei Snyman of the Mashatu Research program in their continuous study of the predator population in Northern Tuli Game Reserve, located in southeastern Botswana in the area bordering South Africa and Zimbabwe, since 2000.

The series of studies examines the effect of human activities on lion populations, particularly on the legal and illegal hunting impact on the social organization of small lion populations; how lions utilize resources in their habitats; and investigating the establishment of corridors for lion movement through less protected areas in order to move between more highly protected areas.

Although Hawaii comprises less than .04 percent of the total land mass of the United States, the islands are home to approximately 44 percent of all endangered species in our country. Almost 90% of those are found nowhere else on Earth. Due to a myriad of threats, scientists estimate that one native Hawaiian plant species is going extinct every year.

After learning of the Zoo’s success on the reintroduction of the Governor Laffan Fern, Diplazium laffanianum, in Bermuda, which had been absent in the wild for more than one hundred years prior to the Zoo’s involvement, the Plant Extinction Prevention Program contacted Omaha's Henry Doorly Zoo and Aquarium's Rare Plant Lab to aid in the Hawaiian recovery plan for their endangered ferns.

Wild tiger populations have been declining to dangerously low numbers due to extinction threats like human conflict and poaching for the illegal wildlife trade. To save this cherished animal, numerous efforts approach the problem from every angle, from protecting tigers in their natural habitat, to ensuring there is enough stored genetic material to protect the species. Contributing to the second part of the equation, the Zoo, in partnership with the Association of Zoo and Aquariums’ Tiger Species Survival Plan (SSP), has created a new Tiger Breeding Center in Omaha and has been selected to participate in the Tiger Genome Project.
