Ready, set, snap! It’s the Nature Conservancy of Canada’s 5th annual Big Backyard BioBlitz.

Deepen your connection and knowledge

Learn more about the living things in your corner of the country. Whether you’re a first-timer or a BioBlitz pro, you’ll be amazed at what you discover.

Enjoy an activity that’s fun for everyone

Add a sense of exploration to your family outing or challenge your friends to see how many cool species you can each spot. Whether you take part for a few days, the whole week or for just an hour, you’ll have a great time while making a difference.

Unlock the power of community science.

Your observations can help scientists and conservation experts map and validate species distributions across the country and monitor changes in ecosystems over time. To date, Big Backyard BioBlitz participants have recorded over 193,000 observations, documenting more than 8,600 species!

No backyard required. Photograph the beetles on your balcony. The buttercups in the park down the street. The beaver you encounter on your canoe trip. As long as it’s in Canada, every contribution counts. Audio recordings are also welcome.

Share your discoveries

From July 28 to August 4, venture out into nature — with friends, family or by yourself — and record your observations.
