Treatment

• It is appropriate to begin treatment of high value ash trees throughout NJ now.
• For any questions about treatment methods, please see the “Insecticide Options for Protecting Ash Trees from Emerald Ash Borer” bulletin.
   

Removal & Recycling

• Any trees determined to be a high safety risk should be removed immediately.
• Any actively infested trees should be cut down and chipped as soon as possible and then left on site (in the municipality).
• For all other ash, it is best to complete removals in the fall and winter. The material must be processed (chipped or de-barked) before emergence (by late April).
• For municipalities, we recommend triage of the ash resource to spread out ash removals over several years.
• Utilize ash wood as completely and as locally as possible. Municipalities can recycle ash for use as firewood or wood chips. The links below are for possible sources for utilization of ash logs. Be as creative as possible, and keep ash wood local!

Do Nothing

• In the landscape (trees planted in yards near homes, along municipal streets, and in parks, playgrounds, campgrounds, etc.), “do nothing” is really not an option, as over 99% of untreated ash trees in the landscape will eventually become infested and die from EAB.
• In wooded areas, the decision to “do nothing” is an option, but should be a conscious decision with the understanding that the ash trees will eventually become infested, die, and fall. This should only be done in secluded areas where there is no/minimal risk associated with these trees when they die, and where there is limited funding and staff for other options.
