Hemlock Woolly Adelgid Regulated Areas

To slow the spread of the Hemlock woolly adelgid to new areas, the Canadian Food Inspection Agency (CFIA) uses measures to control the movement of potentially infested materials. Slowing the spread of HWA will protect Canada's environment and forest resources. It also helps keep international markets open to the forest industry and nurseries in non-regulated parts of Nova Scotia and in non-regulated parts of Canada.
