Florida panther (Puma concolor coryi) recovery currently hinges on the introgression of genetic material from introduced Texas cougars (P c. stanleyana). Recent population growth has occurred in an area that historically supported fluctuating prey populations. It is likely that local prey populations cannot support increased panther numbers over the long term. In addition, current rates of introgression may result in genetic swamping of the Florida panther. About 50% of the population is composed of individuals with Texas genes, and the entire genomic contribution from Texas exceeds 24%. Strategic removals of genetically intercrossed panthers may be warranted. We recommend caution in claiming success through genetic management, and emphasize the need to take a landscape approach to panther recovery.
