EAB management for woodlot owners

With EAB in Missouri, there are many questions and concerns from woodlot owners on what to do with ash trees on their property. The following are a few management recommendations:

  • Until EAB is found in the local area, continue current management practices.
  • When selecting ash trees to thin, first remove those that have low vigor and quality. You should maintain dominant and co-dominant ash trees with good health/form.
  • Know the risks of moving logs and firewood from and to your land. Visit the firewood and quarantine sections of this website for more information.

Research on EAB in forests in Michigan and Ohio has grimly shown that all ash trees are susceptible to EAB attack regardless of ash density, total tree density, ash basal area, total stand basal area, ash diameter (above 1 inch), tree health, and species diversity. Ash survival decreased 30-50 percent over three years in monitored southeastern Michigan infested stands, and models developed from field observations predict that a healthy forest will lose 98% of its ash trees in six years.

There is no way of predicting how fast EAB will spread in Missouri. Without artificial movement in firewood, nursery stock, logs and other ash products it could take years before EAB affects your land. Its best to be prepared and be ready to deal with EAB.
