The power of community science! Illinois Tick-Trefoil (Desmodium illinoense) was considered extirpated in Canada, but an @inaturalist.bsky.social observation in 2018 revealed a remnant population that sparked a COSEWIC reassessment. Just one observation can make a world of difference for a species!
The Canadian Wildlife Federation (CWF) says a plant that had been deemed extinct in Canada has been spotted in the Brantford area.

Ontario’s water is at risk as the provincial government rushes Bill 60 that opens the door to privatization and weaker protections. 💧 This could put profit ahead of public health.
