Join the City Nature Challenge


For the first time ever Côte Saint-Luc is taking part in the City Nature Challenge (CNU).

What is the City Nature Challenge?

The goal of the CNU is to map and share observations of biodiversity across the globe. By participating you will  take part in one of the largest community science events in the world while helping us better understand – and therefore, take care of – nature that lives in and around urban areas.

Where and when does the City Nature Challenge take place?

The CNU takes place over 4 days from April 28 to May 1, in Côte Saint-Luc.

How do I participate in the City Nature Challenge?

The first thing you will need to do is download the iNaturalist app on your smartphone. The application is available for Apple phones (iOS) here and for Androids here. And then between April 28 and May 1, go out in the community and take pictures of plants and animals (wildlife only, not domestic pets) and upload them to the app. iNaturalist will automatically generate suggestions based on your photo and location and your observation will be vetted and shared with scientists working to better understand and protect nature. It’s pretty simple.

After a long winter the City Nature Challenge is the perfect excuse to be outdoors, observe nature coming back to life and help Côte Saint-Luc get on the map!

This international challenge is taking part in more that 45 countries. In Canada, the City Nature Challenge is organized in Canada by the Canadian Wildlife Federation using
