The Department of Natural Resources adopted regulation changes in Title 11 of the Alaska Administrative Code, dealing with prohibited noxious weeds. The regulation change was the result of the existing list, late updated in 1983, not addressing current invasive weed concerns of state and community level land managers and owners. The amendment added two plants to the prohibited weeds list as described in 11 AAC 34.020.

The regulation change was reviewed and approved by the Department of Law and filed by the Lieutenant Governor on June 28, 2007. The amended regulation will go into effect on July 28, 2007. The amended regulation will be printed in Register 183, October 2007 of the Alaska Administrative Code.
