“…As a result, the real impact of foxes on poultry should be analyzed with caution, especially considering that it is based on retrospective estimations that are not supported by written records. Lack of records could have lead farmers to overestimate predator induced losses (Schaefer et al 1981, Stahl et al 2002, something that may have happened in our study site. Poultry predation by domestic dogs could also contribute to the overestimation of chilla damage.…”

“…As entrevistas vêm sendo freqüentemente utilizadas para avaliar as perdas causadas por predadores e fornecer informações sobre a percepção da população em relação ao conflito (por ex., ver Robel et al 1981, Schaefer et al 1981, Oli et al 1994, Manzatti 1999, Mazzolli et al 2002, Conforti & Azevedo 2003, Palmeira 2004, Zimmermann et al 2005, Michalski et al 2006 Para quantificar a predação por onças e levantar a opinião local em relação ao conflito foram realizadas entrevistas semi-estruturadas em 28 propriedades, representando 87% do total de propriedades existentes nas duas comunidades (Figura 2). As entrevistas foram realizadas apenas com o responsável de cada propriedade selecionada.…”

Domestic livestock predation by jaguars (Panthera onca) and pumas (Puma concolor) was recorded from 1998 to 2000 and local opinion to solve the conflict was investigated in two quilombola communities in the Atlantic Forest. The householders were interviewed regularly from May 2000 to January 2001. Predation depended on the number of domestic animals per household, and was apparently selective and possibly seasonal. The economic damage was high when associated with the low livestock number. People's attitude towards predators was negative and most of those surveyed (54%) suggested these animals should be eliminated. Knowing the local perception is essential to adopt a participative management to reduce household losses and to guarantee large cats' conservation.Keywords A predação de rebanhos domésticos por onças-pintadas (Panthera onca) e onças-pardas (Puma concolor) foi quantificada de 1998 a 2000 e a opinião local para resolver o conflito foi investigada em duas comunidades quilombolas na Mata Atlântica. Os responsáveis pelas propriedades foram entrevistados regularmente de maio de 2000 a janeiro de 2001. A predação foi dependente do número de animais domésticos nas propriedades, foi aparentemente seletiva e possivelmente sazonal. O prejuízo econômico foi alto quando associado com o baixo número de criações. A população expressou uma visão bastante negativa frente à presença de onças e a maior parte (54%) sugeriu o extermínio desses animais. Conhecer a percepção local é fundamental para adotar um planejamento participativo que reduza as perdas dos proprietários e garanta a conservação dos grandes felinos.Palavras-chave: conflito homem-natureza, Mata Atlântica, Panthera onca, percepção, Puma concolor.

“…However, these data are believed to provide the most realistic assessment available of actual losses. Schaefer et al (1981) employed several different methods to survey sheep producers regarding predation losses, and based on their own field necropsies, concluded that producers' estimates of losses were realistic. Sheep loss survey data for the most recently available 3-year period (2005)(2006)(2007) in Idaho indicates predation losses ranged from 25.3% to 32.9% and accounted for an average of about 30% of total death losses among Idaho sheep producers (NASS 2008).…”

Gray wolf populations have exceeded anticipated recovery levels since they were first reintroduced to central Idaho in 1995. Although wolf predation on livestock is a relatively minor issue to the livestock industry as a whole, it can be a serious problem for some individual livestock producers who graze their stock in occupied wolf habitat. This paper compares Idaho population estimates for gray wolves with the available information on numbers of livestock killed by wolves in order to estimate numbers of livestock killed per wolf. This information is compared with similar analyses for other species most commonly implicated as predators of livestock in Idaho (coyotes, black bears, and mountain lions). Population estimates for coyotes, black bears, and mountain lions are based on review of available scientific literature and analyses in environmental assessments prepared by Wildlife Services, as well as estimates from the Idaho Department of Fish and Game. Wolf population estimates are based primarily on monitoring information provided by the Idaho Department of Fish and Game and the Nez Perce Tribe. Estimates of numbers of livestock killed by wolves, coyotes, black bears, and mountain lions are based on survey data compiled by the National Agricultural Statistics Service. Rationale for use of various data sets is provided, and limitations of the data are discussed. This analysis suggests that individual wolves are much more likely to prey on livestock than are individuals of any other predator species in Idaho.
