SEZARC is a not-for-profit group based in Yulee, FL. SEZARC is a unique commodity for the zoo community, acting as an interface between scientists, veterinarians and animal managers to bring research science back to an applied conservation management tool.

Working with modern, forward-thinking zoos, aquariums, and wildlife preserves (currently, Birmingham Zoo, Dallas Zoo, Georgia Aquarium, Jacksonville Zoo and Gardens, Lincoln Park Zoo, Micanopy Zoological Preserve, National Aquarium, North Carolina Aquariums, Palm Beach Zoo, White Oak Conservation Foundation, and Zoo Miami), we provide solutions to reproduction challenges, including pregnancy and fertility checks, assisted reproductive techniques and contraception. Importantly, the science of reproduction is a focus, so reproduction challenges are approached scientifically and methodically, generating knowledge databases for diverse endangered species that are then shared with the zoological and scientific community.

SEZARC recognizes the importance of zoos, aquariums, and wildlife centers in educating us about the importance of conservation. For many species, zoos and aquariums are their only home because of insufficient habitat in the wild or overhunting/overfishing. With just a fraction of a population in managed care, sometimes successful breeding programs can be difficult to establish. We work with the animal keepers and veterinarians to help the animals breed and produce offspring. To do this, we work with zoological institutions all around the world, as well as universities and government agencies. Here are some of the groups with which we have worked: Conservation Centers for Species Survival (C2S2), Institute for Breeding Rare and Endangered African Mammals (IBREAM), Wildlife Conservation Research Unit (WildCru), and the Elephant Population Management Program (EPMP).

What We Do

Basic Biology

One of the limitations of solving reproductive
problems in endangered species is that we
know very little about their basic biology...More

Assisted Reproductive Techniques

Such as artificial insemination, can help
circumvent problems such as mate
incompatibility that prevents breeding...More
