Sensitive Data

Illinois Plants is not responsible for the accidental release of sensitive information.  Illinois Plants attempts to repress information on the exact localities of sensitive plant species or locations; however, Illinois Plants claims no responsibility for any breach of this policy.  This includes, but is not limited to, situations in which sensitive species lists change over time, situations in which data donors request the suppression of particular records, and situations in which computer or coding errors result in the release of information.  In short, we will attempt to accommodate requests to suppress sensitive information, but we cannot be held responsible for any breach of that information. If a data source is required to withhold sensitive data from the public, it is the data source’s sole responsibility to withhold that data from the Illinois Plants.
