The Wallis Annenberg Wildlife Crossing is a project for the next century, providing a lasting benefit to wildlife for generations to come. More than two decades of study by the National Park Service in the Los Angeles area has shown roads and development are not only proving deadly for animals trying to cross, but have also created islands of habitat that can genetically isolate all wildlife—from bobcats to birds to lizards. The species most immediately at risk, the mountain lion, could vanish from the area within our lifetime. https://savelacougars.org/the-cause/
