Donated to Ontario Nature in 2003, the Cawthra Mulock Nature Reserve is a valuable contribution to the conservation of nature. Julyan Mulock and the Cawthra Mulock Foundation generously donated the 107-hectare (265-acre) property, ensuring that the land would be protected in perpetuity.

Located just north of Newmarket, the property is a valuable green space in a highly developed area of Ontario. The York Region Greening Strategy identifies it as a key natural area. The reserve also falls within the context of the Government of Ontario’s Greenbelt system. Situated just north of the Oak Ridges Moraine, the rolling hills and forested ridges are a refuge for wildlife.
