2025 Calgary City Nature Challenge Results!
Thank you to everyone who took part in the seventh annual Calgary City Nature Challenge! If there’s one thing we’ve learned over the years, it’s that nature is a pillar of our community. Our urban landscape not only supports a remarkable diversity of life, but also offers endless opportunities for people to explore, discover, and connect with the wonders of the natural world.
Calgary has always been a “City of Parks,” and throughout our local history, countless naturalists have found their inspiration right here at home.
Together, we’re not just observing nature — we’re helping to protect it for generations to come. Your observations matter. By contributing to citizen science, you’re also helping others appreciate, study, and conserve nature — both here in Calgary and around the world.
This event would not be possible without the support of your local (and often nearby) stewardship groups that care for and educate people on the importance of our natural areas. We ♥️ You and your work is never forgotten. Support them as they support us!
Thank you to the organizers at and for rallying the world to come together over nature!
Thank you all — and don’t let up! Spring is just ramping up, and although the City Nature Challenge is a great kickoff for the season, the observations you share year-round are what truly help build the living atlas we’re creating together.
