ELI5. How do you bring back a species from from near extinction?

Question

Saw a post talking about the white Rhino only had 200 animals left but now there are so many more. But how is this done without serious inbreeding. Or is there something I’m missing?

Edit: yes, I know how sexy time works.

At least in America, the AZA (Association of Zoos & Aquariums) maintains studbooks for each animal, one of the primary goals being to maintain genetic diversity. They can recommend transfers between zoos to make sure the gene pool stays diverse. I’m assuming this is only at AZA accredited zoos. [https://www.aza.org/studbooks](https://www.aza.org/studbooks)
