World’s Largest Wildlife Crossing Is Finally Under Way in Los Angeles

Last October, a gray wolf with a purple radio collar was spotted wandering in the mountains about 50 miles north of Downtown Los Angeles. OR-93 — named that because he had traveled from a pack near Mount Hood, Oregon — was the first gray wolf to roam into Southern California in a century; the last one observed in the region had been trapped in 1922. But after weeks of excitement from wolf-watchers, OR-93 was found dead by the I-5 freeway. According to the scientists who tracked his movements, OR-93 had crossed dozens of roads and even several highways during his 1,000-mile journey.
