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.
