Emerald ash borer: where it is regulated, country by country

This page reports what the official source says. It is not legal advice: ask the office named here. It sets out what each agency's own page says about emerald ash borer, a beetle that attacks and kills ash trees, and the date that page gives. For a wider look at pests by country see tree pests and diseases, and for wood and firewood in general see moving wood and firewood.

United States

The USDA Animal and Plant Health Inspection Service says on its emerald ash borer page that it removed its domestic emerald ash borer quarantine regulations in 2020, and that the final rule was effective January 14, 2021. The same page says people spread the beetle over long distances when they move infested ash firewood, logs or nursery stock, and it reports detections in 38 states and the District of Columbia.

The rule itself is in the Federal Register notice of December 15, 2020. It says APHIS is removing the domestic quarantine regulations to direct resources to management and containment of the pest. It also records comments that states would be free to set their own rules on moving host material, and it says APHIS did not propose to remove its import rules for host material from Canada.

State rules stand on their own. The Minnesota Department of Agriculture page lists the beetle as "Regulated" at the state level, says ash material and hardwood firewood may not enter Minnesota from other states without proper certification, and sends readers to a state status map for quarantine boundaries.

Canada

The Canadian Food Inspection Agency says on its regulated areas and items page that moving any ash tree article out of a regulated area, or off a property under a prohibition of movement, without the agency's consent is prohibited. The list of ash tree articles on that page covers whole trees and parts, ash nursery stock, logs and branches, lumber, packaging with ash in it, wood and bark, wood and bark chips, and ash firewood. Moving ash firewood out of a regulated area is prohibited for commercial and private reasons alike. Non-ash firewood can leave a regulated area only through facilities registered in the agency's approved facility program. Yard waste leaving a regulated area is also prohibited, because it may carry ash bark, branches or trimmings. Regulated items that do move must carry a Movement Certificate issued by the agency, and vehicles are cleaned of debris before loading.

The same page names every continental United States state, Alaska and Washington, D.C. as regulated areas in the United States for the purpose of these rules.

Province	Regulated areas as the agency lists them	Latest dated entry on the detections table
British Columbia	City of Burnaby, City of Vancouver, University of British Columbia, University Endowment Lands, City of Surrey, City of New Westminster	July 22, 2026: detection and prohibition of movement, City of Coquitlam
Manitoba	City of Winnipeg	January 24, 2018: regulated area added, City of Winnipeg
Ontario	Named divisions, regional municipalities, counties and districts across the southern and middle parts of the province, and the City of Thunder Bay	March 11, 2025: detection and prohibition of movement, District of Timiskaming
Quebec	Agglomerations of Montreal and Longueuil, named regional county municipalities, and the City of La Tuque	April 30, 2026: regulated area expanded to La Tuque and the regional county municipalities of Bonaventure and Charlevoix-Est
New Brunswick	Madawaska, Victoria, Carleton, York, Sunbury, Queens, Kings, Westmorland and Albert counties	July 30, 2026: detection and prohibition of movement in Restigouche County and Saint John County
Nova Scotia	Halifax County and part of Hants County	July 31, 2026: detection and prohibition of movement, Colchester County

The agency's emerald ash borer page adds that the beetle is most commonly spread through the movement of firewood and other infested ash wood products, and that adult beetles can fly up to 10 kilometers. The regulated-areas page names no area in the other provinces or the territories.

United Kingdom

Forest Research, the research arm of the Forestry Commission, says on its ash dieback page that imports of ash wood and wood products, including firewood, are regulated to protect against introductions of emerald ash borer. It points to GOV.UK for the explanation of those rules. The page gives no list of areas, because the rule is about imports.
