The Nebraska Department of Agriculture confirmed on Wednesday that the first find in the state of emerald ash borer an invasive beetle that attacks and kills all species of ash trees, in a tree located in Pulaski Park in Omaha.
Officials say an emerald ash borer is a small, metallic-green beetle that is about a half and inch long. The larvae of this wood-boring insect tunnel under the bark of ash trees, disrupting the flow of water and nutrients, ultimately causing the tree to die.
“While it is unfortunate that we have confirmation of the pest in Nebraska, it is not unexpected – considering the close proximity to confirmed pest infestations in Iowa, Missouri and Kansas,” said NDA Director Greg Ibach.
“The Nebraska Department of Agriculture, along with the United States Department of Agriculture, the Nebraska Forest Service and members of the Nebraska EAB Working Group have been preparing for the possibility this pest would enter the state.”
The NDA has issued a quarantine prohibiting ash nursery stock from leaving the quarantine area.
Officials say the quarantine also regulates the movement of hardwood firewood and mulch, ash timber products and green waste material out of Douglas, Sarpy Cass, Washington and Dodge counties to assist in the prevention of human-assisted spread of the pest into un-infested areas.
Officials say the Nebraska EAB working group offers the following suggestions to help prevent the human-assisted spread of the pest:
- Use locally-sourced firewood, burning it in the same county where you purchased it. Firewood is a transportation vessel for the pest.
- Only high value ash tress located within 15 miles of a known infestation should be considered for treatment. Trees that are experiencing declining health should be considered for removal.
- If you feel you have located an EAB infestation, please report it to the Nebraska Department of Agriculture at (402) 471-2351, the Nebraska Forest Service at (402) 472-2944 or your local USDA office at (402) 434-2345.
