What Do We Need to Know About Emerald Ash Borer?

Ash tree loss due to emerald ash borer (EAB) is a public issue when it concerns trees in local parks and a homeowner’s issue when deciding what is best for ash trees in the yard.

Green, black and white ash trees are widely planted in South Dakota but are not always a tree of symmetrical beauty. Due to their hardiness and tolerance to weather, soil and moisture issues, they have been widely planted for decades.


But our plentiful native ash is no match for the exotic emerald ash borer. States east of South Dakota, and now Nebraska, are dealing with emerald ash borer devastation of green, black and white ash trees. It has now been confirmed in Sioux Falls.

According the prediction of Dr. John Ball, South Dakota Forest Health Specialist, it is likely to be found in Yankton within five years. He used the rate of spread of Dutch Elm disease spread by insect in the 1970’s for his prediction.

Response to EAB in Yankton was needed. Here’s a short article recently published in the Yankton Press & Dakotan newspaper that addresses the concerns:


City of Yankton aims to be proactive in its response to emerald ash borer while no one wishes for the loss of ash trees. Here’s an article about Yankton’s response plan for public spaces.


This growing season, property owners will see city workers marking ash trees in the right-of-ways along city streets with an “X”. A tag like this one will be put on the home owner’s door.


If you want to interact with some choices about the tree, go to the City of Yankton website or call City Hall about it. With no response from the property owner, the tree and stump will be removed at no cost to the property owner.

  1. Emerald Ash borer supposedly made an appearance in Sonoma County in about 2007, but was never seen again. I really don’t know what could have been mistaken for emerald ash borer, but I am pleased that it is not here yet, or at least does not seem to be here yet.
