City Nature Challenge

This year, Corvallis will join cities around the world in a collaborative effort to share nature observations in the 2026 City Nature Challenge. Join us to document our local biodiversity.  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 collaborate to see what can be accomplished when we all work toward a common goal.

​

WHY? 

  • FUN!! It's like Pokeman in real life!!

  • Connect with Nature, and help others connect with nature!​

  • HELPING SCIENTISTS 

  • Scientists use iNaturalist data to monitor changes in species distribution over time, providing crucial information on how species adapt to urban environments.​

  • The data collected helps researchers understand and protect biodiversity, which is used to make decisions regarding urban environmental management, including pollution reduction and climate resilience.

  • Through citizen science, the platform provides data on species that might otherwise go unnoticed, expanding knowledge of urban, suburban, and sometimes rare flora and fauna.
