Idaho Wilderness: Its wild residents could fill a volume of some of the most iconic American wildlife: From elk and moose to spawning salmon, mountain goats and sheep to black bears and cougars. Efforts are underway to protect central Idaho's Boulder-White Clouds Mountains, designating 330,000 acres as wilderness. The proposed federal legislation would both protect these lands, and ensure economic sustainability. Loggerhead Turtles: These animals make one of the most treacherous journeys of any creatures, without any parental involvement. Human development is making their survival even more dangerous. Sharon Collins of Georgia Public Broadcasting shows us how these amazing reptiles struggle in an epic journey. These large sea turtles are listed as threatened under the Endangered Species Act. Sandfish Lizard: The sandfish is a little lizard that lives in the Sahara Desert. Scientists are fascinated by its slithering moves. It can tuck its limbs close to its body, and literally "swim" through the sand, just like an eel wiggles its way through water. Physicists are studying this little creature, and using it to inspire new robotic moves that could one day help search-and-rescue crews find survivors in piles of rubble, left from disasters like Hurricane Katrina. The little sandfish is teaching us a lot about what it takes to worm through rugged terrain and debris. Wrangling Water: Cattle are not the only things being rounded up in Florida. Ranchers are also herding water! For years, experts have searched for answers about how to increase water storage in the northern Everglades, and reduce the pollution levels. A pilot program pays ranchers to use their low-lying lands for "environmental services" - namely to store water. Water that's captured during the June through October wet season can then be slowly released during dry months into the tributaries of Lake Okeechobee. And it's proving to be a good thing both for the economy and the environment.
