Every step of establishing and maintaining a forest involves forest health
- properly establishing appropriate, healthy trees on productive sites;
- implementing cultural practices that favor vigorous growth of the best trees;
- reducing losses due to pest organisms;
- well planned, careful harvesting that protects standing trees from injury and maintains the integrity of riparian areas.

Don't Move Firewood
Insects damage healthy trees by feeding on their leaves or boring into their trunks. Insect larvae also pose a threat; larvae can be in firewood. When the firewood is moved to an area, areas that may not have been infected by insects can become infected. We provide information about these dangers so you know about the dangers of moving firewood.

The Virginia Department of Agriculture and Consumer Services (VDACS) restricts moving any firewood from a quarantined area, including those states or counties within states under quarantine, from entering Virginia without a proper permit. View the map of quarantined areas. The Virginia Department of Conservation and Recreation (DCR) is enforcing the quarantine as best they can by telling campers entering their parks with firewood to burn it all within 24 hours and not to bring any on their next visit. They are confiscating and replacing any firewood coming from northern Virginia's quarantined counties. If a citizen refuses to replace their firewood with local sources provided by DCR, DCR is imposing a fine commensurate with a Class I misdimeanor. Fines for out of state firewood from quarantined areas violate federal laws and punishments can be more severe.
Even if an area is not under quarantine, it is a good general practice to not move firewood long distances. The quarantine regulations for an area usually lag well behind the arrival of a new invasive speces.
