Discussing a deer that had been killed by a jaguar on El Aribabi Conservation Ranch.ConserVentures founders Roseann & Jonathan Hanson helped start the Sky Island Alliance Wildlife Tracking program in early 2001. Since then it has become one of the most respected citizen-science program in the world, with several hundred volunteers over ten years monitoring important habitats in the Sky Island region. Their data has helped create land use plans for Pima and Santa Cruz counties, and Arizona Department of Transportation's first approved over- and under-highway wildlife crossings. Over the ten years of this ongoing program, Roseann & Jonathan continued to volunteer their time as instructors in the program. In April 2011, they joined Cynthia Wolf, Jessica Lamberton, and Sergio Avila at El Aribabi Conservation Ranch in northern Mexico to teach the next nine volunteers. Photo gallery, click here.
