"Discovery of Endangered Gray Wolf Pack Signals Hope for California's Wildlife Conservation"

Researchers have discovered a new pack of endangered gray wolves in California's Sierra Nevada, several hundred miles away from any other known population of the species. The pack consists of an adult female and her four offspring, and DNA testing revealed that the female is a direct descendant of a wolf that crossed into California from Oregon in 2011. Gray wolves were hunted to extinction in California in the 1920s, and their recent return to the state is a positive sign for wildlife conservation efforts.
