This is a handout from our webinar, "Can Ontario’s Brook Trout Cope with Climate Change?". Climate change is affecting Brook Trout populations in Ontario, with models predicting significant warming. Brook Trout will have varying abilities to cope with climate change based on their local conditions and habitat. Effective conservation and management require specific, evidence-based information on Brook Trout life stages and regions. The community can help by adopting sustainable practices and supporting environmental organizations.
Climate change is having profound effects on aquatic ecosystems and the fish within them. The loss of coldwater stream and lake habitat puts brook trout, a native coldwater specialist, at risk. Brook trout are more resilient than we think when it comes to surviving in warming waters, but there is a threshold over which they cannot survive in the long term. Because climate change is happening faster than organisms can adapt, understanding thermal tolerance thresholds is a critical step towards effective, evidence-based conservation of our coldwater ecosystems and native fish species.
