In several parts of Latin America, the expansion of agriculture over the years has caused loss and reduction of wild fauna natural habitat. Recently, deaths of sheep and cattle have increased due to predation by large carnivores and the resulting retaliation by farmers on predators. Consequently, populations of these top predators have been reduced or have got even locally extinct, leading to imbalances on ecosystems, altered because of the carnivore effects on prey dinamics. The objective of this study is to analyse sheep depredation by puma (Puma concolor), in Central Brazil and in the Colombian Andes and point out preventive and mitigating measures that can be implemented in rural areas. From 2005 to 2014, we visited a ranch in Alto Paraguai, Mato Grosso, Brazil for diagnostic purposes and we compared the death of sheep from diseases and depredation attacks. In 2014, we visited a rural area in the central region of Departamento del Valle del Cauca, at 2814m of altitude in the Colombian Andes, to diagnose sheep predation, implement preventive measures, and evaluate their effectiveness. The results reveal that economic losses due to predation are critical on both studied regions and similar to losses by diseases in Mato Grosso state, Brazil. Thus, we recommend the integration of health management, preventive measures as well as mitigation of depredatory attacks at the local scale and we discuss potential sustainable measures that can be locally implemented by farmers. Furthermore, we recommend that public policies should incorporate scientific results on human-wildlife conflicts to be effective, considering both livestock management and biodiversity conservation. |
