Captive breeding and subsequent release of endangered species is a valuable conservation practice critical in saving species from extinction. When releasing captively bred species back to the wild, conservation agencies usually select more than one release site to reduce the risk of extinction in case of an adverse local event, such as a natural disaster or disease. However, when populations are spatially correlated because of regional stochasticity, the distance between release sites will influence both the overall management cost and the joint probability of extinction. Consequently, when spatial correlation is considered, the distances between release sites create a trade-off between the expected loss should extinction occur and the cost of setup and management. This essay examines (1) the relationship between distances and the probability of extinction, (2) the trade-off created by distances, (3) comparative statics for optimal distances and a correlation parameter, and for optimal distances and the cost of setup and management, (4) a comparison between the outcomes of one, two and three release sites. An example of the California condor is used to illustrate the importance of the trade-off created by distances between the release sites/re-established wild populations
