Abstract

In 1987 the last wild California condor (Gymnogyps californianus) was placed in captivity. The entire population now (numbering only 27 individuals) is distributed between the San Diego Wild Animal Park and the Los Angeles Zoo based on age, sex, and founder line. Assumed unrelatedness of wild caught condors of unknown background would indicate at most 14 founder lines. Though genetic diversity is certainly less than this, for practical purposes, it must be assumed that 14 lines exist. Recovery Team recommendations suggest that 96.7% of the genetic diversity of individual founders be represented in the population prior to release of other progeny. Three geographically distinct, self-supporting populations numbering 100 individuals each are recommended before considering downlisting from endangered to threatened status. The captive production of 25 young in 5 years, raising the population to 52 condors in 1991, gives hope for accomplishing this goal.
