The Texas Parks and Wildlife Department (TPWD) and Texas Master Naturalists are encouraging all Texans to participate in the worldwide 2021 iNaturalist City Nature Challenge, which began today (April 30) and continues through May 3. See which city can document the most species of plant and animal life in this friendly competition—to participate, sign up at and download the free iNaturalist app. Observe on your own or with a group; area group events are listed here.

Take a picture of any type of plant or animal, and the iNaturalist community will help with identification. Every observation contributes to biodiversity science, from a rare butterfly to a common backyard weed. Note: Richardson and surrounding cities compete as part of the DFW Metroplex.
