A GIS layer of the IBA boundaries is now available. To request a copy, please contact Yoyi Steele at 608-266-8169 or yoyi.steele@wisconsin.gov. Please read our spatial data use statement.
There is no charge for IBA spatial data, but a donation to the IBA Endowment Fund is strongly encouraged in lieu of payment.
