Host an Event

San Diego naturalists, let’s unite

We welcome our fellow nature nuts (also known as our peer organizations) in San Diego County to host a 2018 City Nature Challenge event at their headquarters/venue to help encourage residents and tourists to opt outside and participate.

We're using iNaturalist to tally results for observations made in San Diego County. All wild plants and animals count, even non-native species.

The 2018 City Nature Challenge begins Friday, April, 27 at 12 AM PT and ends Monday, April 30 at 11:59 PM PT. Any observation made within the county during the City Nature Challenge will count toward San Diego’s total.

Ways you can help:

1. Spread the word with our partner tool kit

  • Reach out to members, volunteers, staff, colleagues, and friends
  • Print and post this flyer at your location
  • Post on social media
  • Send an e-newsletter

2. Host an event

  • Organize an event at your location during City Nature Challenge (April 27-30) encouraging your community to make iNaturalist observations
  • Hikes, restoration events, and festivals all provide great opportunities for making observations
  • Let us know about your event so we can post it on our website

3. Make observations of your own during the four-day period



We’re hosting City Nature Challenge Partner Meet and Greets in February 2018, where you can learn more. Download the partner toolkit for a flyer and email template, social media examples, usable logos, and iNaturalist tutorials. Questions? Email Citizen Science Manager Lauren Marino Perez.
