The Cowichan Garry Oak Preserve on southern Vancouver Island holds the secret to one of the Nature Conservancy of Canada’s best restoration success stories. Once overrun by invasive plants and agricultural grasses, the preserve now boasts a vibrant community of native species, including many species at risk that rely on the globally rare Garry oak habitat found here. Less than 10 per cent of this ecosystem is left in the world, and yet these woodlands and meadows support the highest biodiversity of plants in coastal British Columbia.
