The City Nature Challenge is an international effort to document nature in cities that will be taking place from April 30 to May 3, 2021. In light of the COVID-19 pandemic, we urge all participants to carefully follow public health guidelines provided by our local governments, as they are changing in real-time. Individual safety and public health are our utmost priority. Please refer to our COVID-19 FAQ page for more information.
Support for Los Angeles' participation was generously provided by Boeing and the Los Angeles Department of Water and Power.
As a participant, it is up to you how much or how little you take part!
City Nature Challenge is about documenting nature where people live, especially in urban areas. In that spirit, here are some ideas for participation in or near your home.
Explore your home or yard
- What can you find in your house?
- What can you see through your windows?
- What are the wild plants growing in your backyard? (weeds count!)
- What insects or other creatures are using the cultivated plants in your backyard as habitat or a food source?
- What observations can you make along the sidewalk in front of your house or apartment complex? (Always be mindful of traffic and safety.)
- Check out more ideas for exploring nature in and around your home.
Explore your neighborhood
- Take a walk and see what other organisms share your neighborhood. Make sure to practice social distancing by keeping space between people of at least 6 feet. Be considerate of others and cross the street, if necessary to maintain distance. (Always be mindful of traffic and safety.)
- Look up to spot birds sitting in trees or on powerlines and telephone poles.
- Look down to find insects, crawling on the pavement or underneath leaves.
- What else might you find?
- Visit your local park. Make sure to practice social distancing by keeping space between people of at least 6 feet. Look in the grass, on plants, under benches and tables, and up in the trees. How many different species will you find?
