Association of Zoos & Aquariums Reproductive Management Center

The SCC is affiliated with the Association of Zoos and Aquariums Reproductive Management Center at the St. Louis Zoo. Contraceptive research carried out in zoos and aquariums has direct applications to the management of wild animal populations found in National Parks and Reserves. The SCC has applied this technology to the management of wildlife including wild horse and urban deer populations across the United States and the world.

SCC researchers coordinate with wildlife groups to provide training and perform field-based application of contraception to wildlife populations.

Did you know?

White Tailed Deer

Location: United States

Population: 30 million

White-tailed deer are known for their impressive swimming abilities. Not only are they fast and agile on land, but they’re also skilled in the water. When needed, these deer can zip through the waves at speeds reaching up to 13 miles per hour! This talent comes in handy for escaping predators, moving around their environment, and exploring new areas to call home.
