The Minnesota Department of Natural Resources urges Fourth of July Holiday week campers to help prevent the spread of invasive forest pests such as the emerald ash borer (EAB).
                   
Susan Burks, DNR Forestry invasive species program coordinator, says to come clean to a campsite by taking a little time to inspect and remove dirt, plants and bugs from clothing, boots, gear, pets and vehicles.

Burks says to use only local or certified firewood and before camping, check for any firewood restrictions at intended campsite.

The Montenews.com reports only firewood purchased at a state park or from a DNR-approved vendor may be brought onto any DNR-administered lands. She recommends staying on designated trails when walking, hiking, biking or riding your horse or OHV.

Burn all remaining firewood before leaving campsite or return it to the campsite host, don't bring firewood home.

In 2010, the EAB was found at the Upper Mississippi River Fish and Wildlife Area of Houston County. Last year, it was found in the city of Shoreview, and in multiple Winona County locations.

To slow the spread of EAB, the Minnesota Department of Agriculture has quarantined Hennepin, Houston, Ramsey and Winona counties.
