Lancaster County Weed Authority

Lancaster County Weed Authority's responsibility is to carry out the State of Nebraska Noxious Weed Control Act, along with the administration of the City of Lincoln's Weed Abatement program since entering into an interlocal agreement with the City of Lincoln in 1996.

This is accomplished by educating landowners informing them of the legal requirements and benefits of controlling noxious weeds as well as overgrown weeds and worthless vegetation on their property.

Lancaster County Noxious Weed program works to protect effectively against designated noxious weeds which constitute a present threat to the continued economic and environmental value of lands in the County. This is accomplished by implementing the mandates of the State of Nebraska Noxious Weed Control Act, setting forth management objectives and plans, methods or practices which utilize a variety of techniques for the integrated management of noxious weeds. By establishing a coordinated program for the integrated management of noxious weeds, it is the County's intent to encourage and require all appropriate and available management methods, while promoting those methods which are the most environmentally benign and which are practical and economically feasible.
