Commissioners took enthusiasm in the document as well as determined to set up a lunch-and-learn treatment to consider it in additional deepness." It is actually by no means an ideal count of deer," Elliott claimed. "However it is actually a fairly sturdy means to consider how deer density compares in different regions.".Document: Deer create at the very least $129M in automobile problems every year.The study staff likewise was actually charged along with calculating the expense of deer populaces to the state.The file discovered the minimum substantial worth of deer to Iowa is actually $181 million annually.
