In ecosystems across the country, the automobile has moved to the top of the food chain, meaning that thousands of moose, cougars, and bears are meeting their ends on asphalt. Now, the Colorado Department of Transportation is hoping that high-tech wild-life detectors might cut down on roadkill.
The testing site for the new detectors is a particularly deadly mile of Highway 160, where 70 percent of all reported collisions between 1999 and 2003 were between cars and animals. Part of the problem is that the stretch is smack in the middle of an important migration corridor for deer.
