Supporting documents for the incidental mountain lion petition Survival of Cougars Caught in NonTargetFoothold Traps and Snares ABSTRACT Cougars Puma concolor occupy mountain ranges throughout the Great Basin Nevada USA where legal trapping of bobcats Lynx rufus is common and some nontarget captures of cougars in bobcat traps occur. Such incidental capture of cougars is an undocumented source of mortality because some cougars die from injuries several weeks after release from traps. We examined causespecific mortality and the effects of capture of cougars in bobcat traps on annual and overall 7year survival during 20092015. We captured 48 cougars of which we followed 33 until death.
