Jessica Hellmann, an ecologist at Notre Dame University in Indiana, is in the midst of exactly the kind of painstaking study that can help guide those who want to move species. Hellmann works, among other places, on
Vancouver Island, studying a kind of oak savanna ecosystem that most people associate with California. The star players of these savannas are called Garry oaks or Oregon white oaks, large trees often gnarled into unique shapes. Under their canopies grow mossy meadows of wildflowers, including buttercups and star- shaped blue camas. For Canadians, this kind of ecosystem is a beloved break from the evergreens that otherwise dominate the landscape. And according to the nonprofit Garry Oak Ecosystems Recovery Team, "approximately 100 species of plants, mammals, reptiles, birds, butterflies and other insects are officially listed as 'at risk' in these ecosystems" in Canada. The range of these Garry oak savannas hugs the Pacific coast from central California to just about halfway up Vancouver Island. These savannas are quite rare in Canada and threatened by land development. Hellmann thinks that British Columbians might be interested in establishing such ecosystems farther north on the island or even on the province's mainland as the climate warms. So one set of questions that her study is asking bears directly on whether such a move would work.
