Wildlife Services Evidence Standards for Determining Livestock Depredations by Mexican Wolves

Wildlife Services’ determination of depredation by Mexican wolves relies solely on the physical evidence available at the time of the investigation. Wildlife Services documents the physical evidence in the investigative report. Timeliness of carcass discovery affects the quality and availability of physical evidence. Wildlife Services makes all reasonable efforts to timely investigate a report of suspected depredation. However, some situations will result in an unknown determination due to insufficient evidence.
