Although whaling is no longer a threat, human interactions still pose the greatest risks to the species. Recovering this population requires measures to mitigate fishing-gear entanglements, vessel strikes, ocean noise pollution and climate change. Success hinges on co-ordinated actions across the Canada-U.S. border.
