Position Description: The federally listed endangered sentry milk-vetch is known from only 12 locations in Grand Canyon National Park (GRCA) and is currently facing threats from trampling and climate change. Maschinski et al. (1997) noted that when multiple threats such as trampling and a changing climate occur simultaneously, sentry milk-vetch population numbers could plummet and move closer to extinction. A prompt response is warranted to trigger sentry milk-vetch recovery efforts. The intern will advance sentry milk-vetch (hereafter referred to as ‘SMV’) recovery efforts through investigating potential degradation of SMV habitat by large ungulates (i.e. bison), surveying for new SMV populations, engaging the public in education and resource stewardship activities, and sharing fin
