Almost 50% of Saturna Island is within the Gulf Islands National Park. Most of the waters surrounding the island are within the proposed National Marine Conservation Area. This unique garry oak ecosystem in the Georgia Strait lowlands is one of the most ecologically at risk natural regions in southern Canada. It supports a rich and diverse group of species and habitats. Each park within the GINPR on Saturna Island, has a very different local ecosystem. From rocky shores to pebbled ones, high ridges to lowland marshes, there is a diverse habitat for thousands of species of flora and fauna.
