Located in prime Great Lakes territory, two protected areas sit side by side, brimming with life, spectacular scemery, and cultural treasures. Bruce Peninsula National Park and Fathom Five National Marine Park are the last refuge in Southern Ontario for many rare species. Thousand-year-old cedars, rare orchids and the Eastern Massassauga Rattlesnake all live with and within the landscape's rocky cracks and crevices. But, life underwater is out of control. Invasive species are taking over. And preserving diversity on this ancient geological backbone is a constant stuggle that requires a delicate balance.
