Lewisville, TX—The Friends of LLELA invite you to a nature’s paradise for the annual City Nature Challenge 2024 by iNaturalist.

What is the City Nature Challenge?
The CNC is an international event that motivates people around the world to find and document wildlife in their own cities. Run by the Community Science teams at the California Academy of Sciences and the Natural History Museum of Los Angeles County (NHM), the CNC is an annual four-day global bioblitz at the end of April, where cities are in a collaboration-meets- friendly-competition to see what can be accomplished when we all work toward a common goal.

How can I participate? 

  • Find Wildlife: This can be any wild plant, animal, or other evidence of life found in your city.
  • Take a Picture or Record a Sound of what you find. Be sure to note the location of the critter or plant. Your camera or phone may be able to gps tag your location for you.
  • Share your observations through the iNaturalist app or website. Download the app for free…If it’s planted or taken care of by people, it is not WILD. Mark it captive/cultivated!

Where can I participate?
Anywhere in the Dallas Fort Worth 7 county area. OR at LLELA – 201 E Jones St, Lewisville, TX 75057

Come spend time with us at LLELA (Lewisville Lake Environmental Learning Area) in Lewisville, Texas. We are a 2,600-acre wildlife area situated at the base of Lewisville Lake. A combination of grasslands, prairies, pocket prairies, marshes, and wooded areas teeming with wildlife. The Elm Fork branch of the Trinity River bisects the property.
