City Nature Challenge: Partner with Us

San Diego naturalists, let’s unite

April 26-29, 2019

We welcome our fellow nature nuts (read: peer organizations) in San Diego County to host a 2019 City Nature Challenge event at their headquarters/venue to help encourage residents and tourists to opt outside and participate.

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 poster and share these fliers at your location (download templates)
  • Post on social media (download template)
  • Send an e-newsletter (download template)
  • If you need images to complement your marketing materials, feel free to use the images in our press room (please include credit and caption info).

2. Host an event

  • Organize an event at your location during City Nature Challenge (April 26-29) 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 event website
  • Use our flier template to share your event

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

4. Identify others observations until May 6

  • Help identify observations that are not yet at the species level.
