The thousand cankers disease quarantine is an “external quarantine” because it prevents movement into Wisconsin from states where TCD has been found.
Where TCD Has Been Found
Arizona, California, Colorado, Idaho, Indiana, Maryland, Nevada, New Mexico, North Carolina, Ohio, Oregon, Pennsylvania, Tennessee, Utah, Virginia and Washington.
Products Covered by the Quarantine
These products cannot enter Wisconsin unless you meet the quarantine requirements:
- Firewood from any species of tree

- Nursery stock
- Bud wood or scion wood (shoots for planting or grafting)
- Green lumber
- Logs, stumps, roots, branches, composted or uncomposted chips
You can bring the above materials into Wisconsin only if:
- You have a certificate signed by a pest control official where it is coming from, stating the materials have:
- Not been exposed to TCD, and explaining the basis for that statement, or
- Been treated to destroy TCD, specifying the date and method of treatment, or
- Been produced, processed, stored, handled or used under conditions that prevent TCD transmission, and describing those conditions, or
- You have a written agreement with the Department of Agriculture, Trade and Consumer Protection that includes your name and address, the type of volume of material that the agreement allows, and the source locations the agreement allows.
