The 2027 event will take place July 26 - August 2, 2027. Sign up now and mark it in your calendar.
This year, a whopping 11,000+ BioBlitzers proved how powerful community science can be.
Thank you to everyone who participated. Together, you documented an amazing 6,300+ species and shared over 68,000+ observations of species across Canada.
All of this data helps conservation experts map species distributions and monitor long-term changes across Canada. They can reveal shifts in migration or hibernation patterns, changes in flowering timelines or variations in fruit and seed production — all potential signs that climate change is affecting plants and wildlife. The more we know about nature, the more we can support it.
Below is just a sample of your amazing observations.
