2009 was an important year for the adoption of AIS laws in Wisconsin:
WDNR Administrative Rule NR 40 became effective September 1, 2009. While primarily an invasive species (aquatic & terrestrial) classivication system with rules addressing "prohibited" and "restricted" species, NR 40 also included provisions restricting the overland movement of AIS. The rule as adopted can be viewed by clicking on the above link.
Act 55 of 2009 repealed outdated and inadequate AIS laws and replaced them with new WI statues in Chapter 30.07. Act 55 can be viewed by clicking on the above link.
A summary of the most significant AIS laws in Wisconsin was prepared in December of 2009 by WDNR Deputy Warden Mac Hannon. The summary and associated penalties for non-compliance can be viewed by clicking HERE.
In addition to AIS laws, special rules became effective April 4, 2008 pertaining to preventing the spread of Viral Hemorrhagic Septicemia VHS. A summary of those rules can be viewed by cliching HERE.
