Emerald ash borer (EAB) has been detected in North Carolina for the first time. The detection was made in Granville County with the collection of an adult beetle that was confirmed by taxonomists. Several other sites in Granville County also had trees with classic signs and symptoms of EAB including D-shaped exit holes, meandering galleries, dieback and thinning crowns, epicormic sprouting, vertical bark splitting, and increased woodpecker activity. There were trees in Person and Vance County that displayed positive signs also. Pictures of what is described above can be found at: http://na.fs.fed.us/spfo/pubs/pest_al/eab/eab.pdf .

On the NCFS Forest Health webpage is a link to Frequently Asked Questions related to EAB with links to additional information. http://www.ncforestservice.gov/forest_health/fh_eabfaq.htm . Most information you might need can be found here.

Because of the serious nature of this invasive pest, a quarantine has been implemented for Granville, Person and Vance Counties. This quarantine will restrict the movement of ash trees, ash logs, etc. from these counties to other areas of the state. It will also restrict the movement of hardwood firewood from these areas. These are the same as those imposed in other states where EAB has been found as this is a federally regulated pest. If you want to know more about regulations/quarantines, contact the NCDA Plant Industry Division directly.

Forest Health staff will be conducting training/field workshops for NCFS personnel and others working in forestry, natural resource management and horticulture in and around affected counties in the near future. These will highlight EAB awareness, identification, life cycle and control, including field visits to some positive sites.

Under natural conditions, EAB spreads about 5 miles per year. However, it has spread longer distances in short periods hitchhiking on firewood, prompting a nationwide campaign to encourage people not to move firewood, or to buy firewood from local or certified sources. This has been found to be the most effective way to slow the spread of this pest.
