HIGH PARK AWARDED GRANT High Park has been named as one of the organizations to receive funding under the new Ontario Species at Risk Stewardship Fund. High Park Initiatives and the High Park Community Advisory Council applied for funding for habitat restoration, publication of educational booklets (reprinting A Jewel of Toronto’s Park System and a new guidebook focusing on plant species found in the park), and research projects to support the restoration effort. Restoration work fosters the expansion of wild lupine habitat in the Oak Savannah. This is the food plant of the extirpated Karner Blue butterfly, a species on the province's Protection to Support Recovery list. High Park's stands of Wild Lupine are expected to play a key role in a reintroduction program being planned by Toronto Zoo, by providing food for larvae. HIGH PARK NEEDS YOUR HELP! Volunteers are an essential part of the High Park Species at Risk project. You could help with planting events (see Coming Events on page 19) or publishing projects.
