City Nature Challenge 2021

Once again Calgary (and the nearby communities of Cochrane, Okotoks, Airdrie, and Chestermere, plus Glenbow Ranch Provincial Park) will be participating in the City Nature Challenge. From April 30 to May 3, anyone can participate in this fun, important, and fast-growing citizen-science project. People in hundreds of cities around the world will be photographing plants, birds, mammals, and anything else in nature to capture a record of worldwide urban biodiversity.

From the CNC 2021 Calgary Metropolitan Region website:

Look for nature in your yards, neighborhoods, and local parks. Explore anywhere in Calgary, Cochrane, Okotoks, Airdrie, Chestermere, and Glenbow Ranch Provincial Park. Any photos taken April 30-May 3 and shared to iNaturalist before May 9 will be included.   Join the 2021 iNaturalist Project to Stay up to date!

So starting on Friday morning, take as many photos as you can of birds, plants, insects, and any other living things. You will have until May 9 to upload your photos to iNaturalist.

City Nature Challenge 2020

  • April 24-27, 2020
  • Modified due to Covid-19
  • Expanded to Calgary metropolitan area
  • Everyone welcome to participate!

The second annual Calgary City Nature Challenge will go ahead on April 24-27, 2020. Once again, Matthew Wallace is doing a great job of organizing and promoting this valuable citizen science project.

This year, an expanded Calgary metropolitan area will include Airdrie, Cochrane, Okotoks, and Chestermere. Calgary will be competing with over 200 other cities around the world to try to identify as many species of wildlife as possible.

Last year there were many organized group activities in the CNC, but due to Covid-19 these will not be taking place this year. However, people can easily participate by themselves by taking photos of any living thing and uploading it to the iNaturalist website or app.

Calgary City Nature Challenge

For all the updated information on how to participate, see the Calgary CNC website here.

Download the iNaturalist app or sign up on the webpage. Then start taking pictures of wildlife and uploading them. There is no need to wait until April 24 to get started, but please try to help out on that weekend!

City Nature Challenge Events

The City Nature Challenge is under way! From April 26 through to midnight on April 29 we need Calgary naturalists to take as many photos as possible of any and all wildlife (birds, mammals, fish, plants, lichen; anything!) within the city limits.

You will have until May 5 to upload all your photos to the iNaturalist website or phone app. No need to learn all the ins and outs of iNaturalist right away if you haven’t done so (the sooner the better of course, and it is very easy!), and no need to know what it is you are photographing – the site will suggest ID’s and the iNaturalist community will confirm them.

There are many organized events planned for the challenge, including six today (Friday April 26) and many more over the following three days. See this page for all the events planned over the four days and come out and help us document the wildlife of Calgary. You can also participate on your own all day, every day!

Calgary is one of 163 cities worldwide taking part in this challenge, and is the northernmost city. We want to try to win the competition for most participants and most observations made. We are also having a friendly competition with Halifax, the only other Canadian city involved. So get outside!

City Nature Challenge Workshop at Pearce Estate

Come out to Pearce Estate Park in Calgary this Saturday morning to learn how to participate in the City Nature Challenge.

At this event you will learn all about how to use the iNaturalist app and how to make observations so you can participate in the upcoming City Nature Challenge.

Everyone is welcome; just show up at 10 am at Pearce Estate with your phone, tablet, or camera. Sign up for an iNaturalist account on the app or online first. Be prepared to do a mini-BioBlitz of all the wild animals, insects and plants we can find!

Please read all about it on the Calgary CNC website here. There will be more such events coming up before the Challenge so if you can’t make it this week, plan to attend a future one.
