Accessing DNR Nature Preserve Site Locations

Illinois Department of Natural Resources Nature Preserve Commission Sites are considered "sensitive areas" for the purpose of dicamba application to soybean.  Therefore it is vital that applicators identify if any of these DNR sites are located near soybean fields where Engenia, Xtendimax, FeXapan or Tavium may be applied.  IFCA worked with DNR to gain access to files of these sites that you can download into your spray application software.  We have an icon for DNR sites featured on the IFCA hompage at or you can go directly to the feature on the IFCA website here:  
There are 9 DNR areas in the State.  Click on your area and you can see a listing of all the names of the DNR Nature Preserve sites by County within that area.  If you then click on the name of the site, you can view detailed information about each Nature Preserve site including the size, exact location and a topo map showing the location of the nature preserve.  
If you determine that any of these preserves are adjacent or neighboring to a field where you wish to apply dicamba to soybean, you can download a ZIP file to integrate the coordinates of these sites into your pesticide application software.  
If you have questions about DNR Nature Preserve sites, please contact IFCA.
The dicamba 24c Special Local Needs labels for each dicamba product are also available on the IFCA website here:  The 24c labels in Illinois mandate a June 30, 2019 cut-off date for application, define residential areas that are adjacent, neighboring and down-wind as a "DO NOT SPRAY" label requirement and provide guidance on protecting other sensitive areas.
