Transporting Firewood Leads to Unintended Consequences

by Marcia Anderson

A colleague of mine who lives in Maine told me she wanted to bring firewood from her cordwood pile at home into a New Hampshire campground. Although she lives .2 miles from the border with New Hampshire, close enough that an ant’s pace would get you there in a day, restrictions on transporting firewood meant she had to wait and buy wood for $5 a bundle in New Hampshire.

Firewood has historically been moved with little consideration of the pests it might harbor. However, the issue is getting increasing attention. This year, the US Department of Agriculture and several states put out urgent pleas to avoid transporting firewood.

Over the past 15 years, exotic insects like the Asian longhorned beetle, emerald ash borer and hemlock woolly adelgid have killed millions of trees in the United States. Once established in new areas, these pests can quickly kill trees forests, parks, towns and campgrounds. (see related blog).

Firewood is an especially troublesome means by which pests are spread. According to USDA, the best preventative measure to protect forests from these pests is by limiting the movement of infested materials, including firewood.

Firewood is frequently moved long distances by campers and retailers. Not surprisingly, pest infestations are showing up around campgrounds and highway rest areas. In many states, all trees used as firewood are now regulated since they have the potential to harbor invasive insects and diseases.

Thirty states have imposed various levels of quarantine as a result of the emerald ash borer. Regulations vary by state, but generally include restrictions on importing firewood, movement of firewood within the state, and transportation of firewood into state, local and federal parks. In New England, the emerald ash borer was detected in Connecticut,

Massachusetts, New Hampshire and Rhode Island, along with neighboring NY and Canada and all have various levels of wood quarantine in place. For example, the border was confirmed in all eight Connecticut counties so now that state has restrictions on the movement of all hardwood firewood. People who move firewood must have a document stating the origin and destination of the firewood. Some states have regulations that do not allow wood to be transported beyond a 50-mile radius of a restricted zone. A restricted zone is the quarantine of an infested area that prohibits the movement of logs and firewood outside of the zone. Check USDA’s quarantine map before you move firewood, even to another town. Because EAB does not travel far on its own, limiting human transportation of infested material will slow its spread.

It is recommended to use locally-sourced firewood, or firewood that has verified as pest free. Firewood producers and dealers must provide documentation on the source of their firewood. Seasoned wood may still have insects that can survive for many months. Only firewood heat-treated, kiln-dried at 160° F for at least 75 minutes can be brought into parks, and only with documentation.

RVs and other vehicles that have been parked for long periods can also harbor tree pests and their eggs. Take the time to check your vehicle, especially the wheel wells, and remove any insects. You can also wash down your camper between trips to help remove any hitchhiking pests.

What is at risk from transporting these pests? The trees in your backyard, along your streets, and in your neighborhood, along with the wildlife that depends on them. Jobs in the timber and forestry industries and manufacturing sector, things like flooring, cabinets, pallets, and even baseball bats, are also impacted. Cities and towns then have to pay to remove the hazardous trees killed by pests.

Although my colleague was frustrated she could not bring her own wood, the regulations are meant to protect all of us and our environment. So do your part to help sustain the health of our great forest resources and neighborhood trees.

Unintended Consequences of Transporting Firewood

by Marcia Anderson

Over the past 15 years, exotic insects like the Asian longhorned beetle, emerald ash borer (EAB), and hemlock woolly adelgid have killed millions of trees in cities and forests across the United States. Once established in new areas, these pests can quickly kill trees in our favorite forests, parks, communities, and campgrounds. The U.S. Department of Agriculture (USDA) estimates that over 30 million ash trees have already been killed by the emerald ash borer in Michigan alone, with millions dead or dying in other states (see related blog).

Firewood has been shown to be an especially troublesome means by which pests are spread. According to the USDA, the best preventative measure to protect our uninfested urban and rural forests from these pests is to limit the movement of infested materials, including firewood.

Firewood is frequently moved long distances by campers and retailers. Not surprisingly, pest infestations are showing up around campgrounds and highway rest areas. In many states, all trees used as firewood are now regulated since they have the potential to harbor invasive insects and diseases.

To protect forests and trees that are threatened by a host of invasive insects and diseases, regulation has become necessary. While regulations vary by state, they generally include restrictions on importing firewood, the movement of firewood within the state, and the transportation of firewood into state, local and federal parks.

Thirty states have imposed various levels of quarantine as a result of the emerald ash borer. In the Northeast alone, most states have restrictions on the movement of wood products. Other states, including Minnesota, Wisconsin, Michigan, Illinois, Indiana, Kentucky, Ohio, and Maryland, have also imposed regulations on the movement and importation of firewood. Some regulations do not allow the transport of wood beyond a 50-mile radius of an EAB-restricted zone. A restricted zone is the quarantine of an infested area that prohibits the movement of logs and firewood outside of the zone. Check USDA’s quarantine map before you move firewood, even to another town. Because EAB does not travel far on its own, limiting human transportation of infested material will slow its spread.

It is recommended to use locally-sourced firewood, or firewood that has been confirmed as pest free. Firewood producers and dealers must provide documentation on the source of their firewood. Note that seasoned wood alone is not an adequate treatment method because some insects can survive in untreated firewood for many months. Only firewood that is heat treated, kiln-dried (160° F for at least 75 minutes), is allowed to be brought into parks with source documentation.

Be warned that RVs and other vehicles that have been parked for long periods of time can also harbor tree pests and their eggs. If not removed prior to a road trip, these vehicles can introduce pests into a previously uninfested area. So, take the time to check your vehicle, especially the wheel wells, and remove any insects you find. You can also wash down your camper between trips to help remove any hitchhiking pests.

What is at risk from transporting these pests? The trees in your backyard, along your streets, and in your neighborhood, along with the wildlife that depend on them. In addition, jobs in the timber and forestry industries and manufacturing sector (flooring, cabinets, pallets, and even baseball bats) are impacted. A direct consequence to taxpayers are the costs borne by cities and towns to remove the hazardous trees killed by these pests.

Preventing the spread of pests is one component of an Integrated Pest Management program. Doing your part will help sustain the health of our great forest resources and neighborhood trees.

Green Heart: Burn Wise for Your Heart

By Ann Brown

February—American Heart Month—is a time I renew my commitment to protect my heart.

I try to eat a healthier diet and exercise more. I check the local air quality before going outside to exercise since fine particle pollution in the air has been linked to heart disease. Fine particles harm the heart and blood vessels and can lead to heart attacks, stroke, and congestive heart failure, especially in people with heart disease.

I am aware of the environmental link between fine particle pollution and heart disease, but I didn’t realize until joining EPA’s Burn Wise program recently that smoke from wood stoves and wood-burning fireplaces is a significant source of fine particle pollution in many parts of the country. I was surprised to find out that there are about 12 million wood stoves and 29 million fireplaces in the U.S.

The good news is that people who burn wood can reduce fine particle pollution by following some simple steps. One way is to use a moisture meter, an inexpensive tool that you stick into wood to find out whether the wood is dry enough to burn efficiently. If the wood is wet, it creates more smoke and fine particle pollution in the air that can harm your health. Wet wood also costs you money and time since it will not produce as much heat. Find out more about how to use a moisture meter in the video Wet Wood is a Waste.

I’ve also recently learned that drying wood is easy, but requires a few steps. The best way to dry wood is to split it, stack it to allow air to circulate, and cover it or store it in a wood shed. This promotes drying and cleaner burning.  Find out more about how to properly split, stack, cover and store your wood in the video Split, Stack, Cover, Store.

These practices are a win-win for your pocketbook and your heart.  Visit EPA’s Burn Wise website to learn  more about ways to burn the right wood, the right way, in the right wood-burning appliance.
