The Emerald Ash Borer Threat
The emerald ash borer is a highly destructive, invasive species of beetle that has become a serious threat to ash trees in Iowa and across the United States.
It is native to parts of Asia, but was accidentally introduced to the United States in the 1990s.
Since then, it has spread rapidly and has been responsible for the death of millions of ash trees in the United States.
In Iowa, the emerald ash borer has been found in 62 counties, and it has been estimated that up to 90 percent of the states ash trees could be lost due to this pest.
The emerald ash borer feeds on the inner bark of ash trees, disrupting the trees ability to transport water and nutrients.
This can lead to wilting, discoloration of the leaves, and ultimately the death of the tree.
The beetle can also spread to other trees, as female beetles lay their eggs in the bark of other ash trees.
The threat of the emerald ash borer has led to increased awareness of the importance of ash trees in Iowa and other states.
In Iowa, the Department of Natural Resources has launched a campaign to educate the public about the dangers of the emerald ash borer and how to identify and report infestations.
