Invasive Species Update

This particle Oak has been found in New Jersey as well.  As a courtesy, please see the below information on how to best protect Oak Trees,

DEC is Taking Action

DEC will be establishing a protective zone encompassing the two new locations in the Town of Glenville. Removal of oak wood or firewood of any species from the protective zone will be prohibited. Since no effective chemical treatment for oak wilt currently exists, DEC will use other treatment methods at each location, depending on site characteristics. These can include:

  • Removing and destroying infected trees,
  • Cutting down a buffer of adjacent trees, and
  • Digging trenches to prevent spread from one oak to another through roots.


How to Protect Oak Trees


  • Prune oaks between October and February – NOT during the growing season when insects are active. Oak wilt can be spread by beetles attracted to freshly cut or injured trees. 
  • Follow the rules of the protective zone.
  • Learn to identify oak wilt's symptoms:
    • Discoloration around the entire leaf edge (see photo) and
    • Sudden loss of a substantial portion of leaves during the summer.
  • Use local firewood. Firewood can transport oak wilt and other deadly pests and diseases to new areas.
