Lancaster County Weed Control Superintendent

Brent serves as the Lancaster County Weed Superintendent based in Lincoln, NE. He’s spent 25 years working with invasive plants and has served on numerous State and national organizations including serving on the NAWMA (now NAISMA) Board of Director’s and as the organizations President, as well as the Nebraska Weed Control Association’s President. He currently serves as the Chair for the Governor’s Riparian Vegetation Management Task Force.

As superintendent in Lancaster County he is responsible for carrying out the State’s Noxious Weed Act as well as working with, and educating landowners on invasive plants, their control methods, and potential they have on our environment. 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.
