Explore the Watershed: New Wildlife Video and Trail Camera Gallery

March 11, 2026

Mountain lion cubs captured on a trail camera in the Yuba watershed

The Yuba watershed supports a remarkable range of wildlife, and we've been quietly building a dedicated space to share what our cameras and field biologists have been seeing. Today we're excited to announce two new additions to the Watershed Wildlife page.

Western Pond Turtle Video

Field biologist Jeff Alvarez walks through what a western pond turtle's shell can reveal — its sex, approximate age, and the history of injuries and recoveries written into the scutes. Western pond turtles (Actinemys marmorata) are a California Species of Special Concern, and the populations in the lower Yuba watershed have long been a focus of informal monitoring by local naturalists.

The video is a short, accessible introduction to reading these animals in the field — worth watching whether you're a seasoned naturalist or just curious about what lives along our creeks and rivers.

Trail Camera Gallery: 47 Species Portraits

Our trail cameras are placed throughout the watershed at known wildlife travel corridors, meadow edges, and riparian areas. Since we started running them, they've documented an impressive cross-section of the animals that move through this landscape when people aren't around.

The newly expanded gallery includes 47 images and videos spanning mammals, birds, and reptiles:

  • Large mammals: black bear (adults, subadult, and cubs), mountain lion and cubs, bobcat, gray fox
  • Medium mammals: ringtail, raccoon, Virginia opossum, American mink, striped skunk, dusky-footed woodrat
  • Small mammals: northern flying squirrel, Douglas squirrel, western gray squirrel, black-tailed jackrabbit, mouse
  • Birds: pileated woodpecker, northern saw-whet owl, band-tailed pigeon, common raven, dark-eyed junco, hermit thrush, hairy woodpecker, spotted towhee
  • Reptiles and amphibians: California toad, and more

Each image is captioned with the species name. Click any thumbnail to open the full-size photo in a lightbox.
