California Biodiversity Challenge 2026
Spend October documenting the wildlife and plants where you already are — a backyard, a schoolyard, a hiking trail, a storm drain. Photograph what you find, upload it to iNaturalist, and your observations join a public dataset that researchers actually use. No prior experience and no equipment beyond a phone camera.
- Observations are recorded through iNaturalist, a free public science platform.
- Anywhere in California counts — there is no travel and no set meeting time.
- Service hours are verified against your iNaturalist observation count.
- Service hours
- 2 hours for 1–24 verified observations, 4 hours for 25–50
- Who it's for
- Students, families, and anyone in California with a phone
Hosted by EcoQuest Foundation, a 501(c)(3) nonprofit
