According to KCET, National Park Service researchers have installed a series wildlife cameras across 30 miles of the river’s course to try and get answers on how foxes, bobcats, opossums, coyotes, skunks, raccoons and other mammals use the area.

Around 30 cameras have been installed this year, from relatively wild areas in Griffith Park to little strips of property right outside of downtown L.A. that could be as small as 10×20 feet. The program will hopefully help determine whether the LA River acts as a wildlife corridor between the more than 150,000-acre Santa Monica Mountains National Recreation Area and spaces in the city.

Eventually, the public can help tag photos by going on a citizen science website.

See you on the river, Jim Burns
