Should your state restrict transporting firewood to protect local forests from invasive species?
Michigan will implement a statewide quarantine on untreated out-of-state firewood beginning January 1, 2027, to combat the spread of the spotted lanternfly. This policy aims to protect the local environment as the pest, which feeds on over 70 types of plants, reaches new areas.
Why it matters
Preventing the introduction of invasive species is significantly more effective than managing them once they have established an infestation. Restricting the movement of firewood helps protect Michigan's diverse plant life from pests that travel through human activity.
The spotted lanternfly, an invasive pest that feeds on over 70 types of plants, is now established in seven Michigan counties, including recent detections in Berrian County. Future monitoring will determine the effectiveness of the quarantine in slowing this geographic spread.
The players
Michigan Department of Agriculture and Rural Development
The state agency responsible for overseeing agricultural health and regulating the movement of goods to prevent pest spread.
Michigan Invasive Species Program
A collaborative state effort focused on the detection and management of non-native species threatening local ecosystems.
The details
The quarantine requires that all firewood brought into Michigan be certified as heat-treated by state or federal departments to ensure it is free of pests. Heat treatment kills invasive insects and larvae that might otherwise hide deep within the wood. By standardizing this requirement, Michigan aligns its protective efforts with existing policies in states like Wisconsin and Minnesota.
Timeline
November 12, 2026: The Michigan Invasive Species Program will host a webinar from 9 to 10 a.m.
January 1, 2027: The firewood quarantine officially takes effect.
2027: The state will implement the quarantine through ongoing education and awareness efforts.
Health Landscape
This measure strengthens the state's plant health protections under the existing framework of Act 189 of 1931. It follows a growing regional trend of states implementing strict firewood movement standards to curb the spread of invasive species.
If you are planning a camping trip to Michigan after January 1, 2027, you must ensure any firewood you bring is certified heat-treated. Check the source of your wood locally or consult resources to confirm it meets state requirements before you travel.
The takeaway
Invasive species often travel across state lines through untreated firewood, putting local ecosystems at risk. Always verify that your wood is certified heat-treated before transporting it across state borders to help prevent the introduction of pests like the spotted lanternfly.
What happens next
The Michigan Invasive Species Program will host a webinar on November 12, 2026, from 9 to 10 a.m. to discuss the implementation of the new firewood quarantine requirements.
