Los Angeles County is home to beautiful beaches, spectacular mountains, as well as some very urbanized areas. Let's show the world how much nature is in L.A.! All you need to do is to take photos of the wildlife you see in your backyard, your local park, your school yard, or in any urban, suburban, or rural area in Los Angeles County. Then upload your observations to iNaturalist so you can help us document nature in L.A. Observation period for City Nature Challenge 2024 runs April 26 - April 29.
