I first learned of Sky Island Alliance when I visited Southern Arizona 7 years ago. Several SIA staffers worked on a mountain lion track count project at Saguaro National Park for which I was volunteering. I was impressed by their knowledge, vision and passion for the Sky Islands -- and also by their very "doable" plan for preserving the area with the help of the community. I live on the East Coast, but I continue to support the SIA and the work they're doing to keep the unique and biologically diverse Sky Islands area healthy.
