What is the Advisory Council?

The Nebraska Invasive Species Council (NISC) was formed in 2012 by the Nebraska Legislature to serve as an advisory council for state invasive species policy and to coordinate management and research efforts across the state focused on preventing, detecting and managing invasive species. The Nebraska Invasive Species Program coordinates the council and provides outreach, management and research information to the public and stakeholders.  A copy of the legislation creating this Council can be accessed here.  A copy of the Council's adaptive managment plan can be accessed hereThe Council's annual report can be accessed here.

  2. Develop and periodically update a statewide adaptive management plan for invasive species as described in section 15 of the legislation;
  3. Serve as a forum for discussion, identification, and understanding of invasive species issues;
  4. Facilitate the communication, cooperation, and coordination of local, state, federal, private, and nongovernmental entities for the prevention, control, and management of invasive species;
  5. Assist with public outreach and awareness of invasive species issues; and

Brent serves as the Lancaster County Weed Superintendent based in Lincoln, NE.

The Nebraska Invasive Species Council (NISC) plays a critical role in education and outreach across all taxa.  NISC is very important to the success of all invasive species control programs.  It is, by far, more effective to prevent the spread of invasives, than it is to try and treat them after they become established.
