Poop-sniffing dogs aid Joshua Tree mountain lions

Rescue dogs are aiding researchers in collecting DNA from animal droppings along State Route 62 near Joshua Tree National Park to assess the effectiveness of upcoming wildlife crossings. The crossings aim to reconnect isolated populations of mountain lions and other species, reducing the risk of inbreeding and ecosystem decline caused by roadkill and habitat fragmentation. This innovative survey method will compare pre- and post-construction data to determine if the crossings improve animal movement and genetic diversity. California has prioritized expanding wildlife crossings to mitigate road-related wildlife mortality and ecosystem disruption.
