We evaluated local opinion about reducing livestock losses to puma (Puma concolor) and the potential for conflict among livestock breeders inside a protected area in the highlands of a southeastern Brazilian Atlantic forest. We also quantified the number and type of livestock losses, and determined if predation by puma was correlated with property profile and landscape characteristics. We conducted semistructured interviews with 42 livestock breeders sampled in 36 rural properties. When asked how to reduce predation, 33% of livestock breeders refused to answer, 26% suggested improving livestock husbandry practices, 19% stated that there was no appropriate action, 17% favored removing the "problem" individual, and 5 % suggested killing the puma. Opinion on how to solve predation was independent of herd size and history of losses, and was correlated with respondent age class. Older respondents tended to suggest removing or killing pumas. Attitudes toward predation represented high potential for conflict among livestock breeders who demonstrated high discordance among responses. Horses were the most common prey (51%), followed by cattle (28%), sheep (17%), and goats (4%); totaling 47 animals attacked between 2004 and 2007. Annual predation was approximately 12 ± 5 animals, equivalent to 0.4% of the total livestock. Property elevation and distance from the urban center were the main predictors of predation probability. This survey used a novel approach that has not been addressed directly in other studies on livestock predation and demonstrated that the high potential for conflict among livestock breeders should be considered before implementing management actions.
