City Nature Challenge 2026

This article is not just an invitation it is a true challenge!

How many times have you wondered what that plant you see every day on the street is? Or which species live around you, even within the urban environment? The City Nature Challenge gives us the opportunity to discover the nature that surrounds us and record it!

This year, iSea, in collaboration with HCMR, is participating in the City Nature Challenge in Attica and Thessaloniki, from April 24 to 27. Our goal is to explore nature and record biodiversity through the iNaturalist platform (https://greece.inaturalist.org/).

How you can participate

You can also become part of this effort:

• By joining one of our organized activities
• Or by organizing your own activity

For those who would like to learn more about Citizen Science and iNaturalist, you can join our webinar on April 22 at 18:00.
