It’s easy to participate. Don't miss out!

Join thousands of newbies and seasoned bioblitzers across the country in the Nature Conservancy of Canada’s Big Backyard BioBlitz. It’s a great way to get closer to nature — and contribute to the protection of the species you love!

All you need is a smartphone, tablet or digital camera. Just snap photos of plants, animals, insects and other creatures wherever you happen to be. Then share your observations to help scientists take stock of local biodiversity, track rare species and fight invasive ones.

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’ll 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 spot.

Contribute to conservation science

Your observations can help scientists take stock of local biodiversity, track rare species and fight invasive ones. Last year, Big Backyard BioBlitz participants documented an incredible 5,323 different species!

It's easy to participate, here's how:

1. Signup! You’ll receive easy-to-follow instructions on how to take part, and resources to help you along the way.

2. Participate anywhere — 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.

3. Share your discoveries. Between August 3-7 venture out into your neighbourhood — with friends, family or by yourself — and record your observations.
