Ash Trees in Peril: What Can We Do?
Emerald Ash Borer, an exotic insect responsible for the loss of more than 100 million Ash trees in the United States over the past two decades, has now been discovered in Sioux Falls. This is the first confirmed infestation in South Dakota.
Emerald Ash Borers (EAB) were found in northern Sioux Falls. The South Dakota Department of Agriculture received confirmation on May 9 that the insect is indeed EAB. The confirmation was made by the Animal Plant Health Inspection Service (APHIS), a division of the United States Department of Agriculture. The infestation so far appears to be confined to a relatively small area. The south Dakota Department of Agriculture is conducting surveys to verify the extent of the infestation.
Will we lose our Ash trees?
The answer is yes, unless a tree is periodically treated with an insecticide indefinitely. Typically, a community loses all their untreated Ash trees within a ten-year period following detection. Tree owners who live in Sioux Falls should consider treating their individual trees for this insect. It is not practical for large plantings.
There is no need to call the City, Cooperative Extension, or the SD Department of Agriculture to inspect your Ash tree if you live within the city. If you want to protect your Ash tree, it should be treated.
