The newly signed Great Bear Rainforest agreement is under attack for failing to adequately protect of one of the world’s most fragile landscapes — subterranean karst, including features such as caves and sinkholes. The agreement “does not address karst specifically, it’s left to chance,” warned Paul Griffiths, a karst authority and scientist based in Campbell River. “If you have a cave in the Great Bear Rainforest it is not automatically protected. They need to address karst directly with a specific objective.”
