The Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) has imposed an exterior quarantine on items that could carry hemlock woolly adelgid (HWA). An exterior quarantine restricts import of some plant products from areas infested with HWA.
Areas Covered by the Quarantine
The quarantine applies to the entire states of Alaska, California, Connecticut, Delaware, Georgia, Idaho, Kentucky, Maine, Maryland, Massachusetts, Michigan, New Hampshire, New York, New Jersey, North Carolina, Ohio, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Vermont, Virginia, Washington, and West Virginia; the District of Columbia; the Canadian provinces of British Columbia and Nova Scotia; and any state or area declared by responsible agencies as infested with HWA.
Items Covered by the Quarantine
- Any living
life stage of HWA
- Hemlock nursery
stock or seedlings
- Hemlock logs
or lumber with bark
- Hemlock bark
or chips with bark
- Any other item
that a pest control official determines poses a risk of spreading HWA
Exceptions
Regulated items can be imported into Wisconsin, if accompanied by a phytosanitary certificate signed by a pest control official in the state or province of origin who has inspected the items and certified that the items:
- Originate from
non-infested premises and have not been exposed to HWA, or
- Were free of HWA at the time of inspection, or
- Have been effectively treated to destroy HWA, or
- Were produced,
processed, stored, handled, or used under conditions that would prevent
transmission of HWA.
Regulated items may also be exempt from the quarantine if importing nurseries or other businesses set up a compliance agreement with DATCP. The agreement must document the source, date, size, method and frequency of hemlock shipments, as well as import conditions that effectively prevent the spread of HWA.
