Weed Management

La Plata County Weed Office

Noxious weeds are more than plants out of place; they are non-native plants that are disrupting our native vegetation and ecosystems. Noxious weeds thrive because they have no natural controls and are able to adapt to varied climatic conditions. They flourish in areas that have been disturbed and lack native vegetation.

Our Mission
The purpose of the Weed Management Program is to provide compliance, information and county roads/properties weed management services to landowners, residents and visitors so they can benefit from reduced weed infestations

Program Overview
The goal of La Plata County Weed Management Program is to manage and/or eradicate noxious weeds in our region. We do this by controlling the weeds on County Roads and County Properties, and also through educating and helping landowners with vegetation on their property.

Large infestations can be stopped, reduced, managed and sometimes eventually eradicated. Smaller invasions can most times be fully eradicated before they have a chance to become established, and then spread throughout a sub region in the County. By accomplishing this landowners and managers help stop noxious weeds from forcing out native plants and animals from their natural environment.

La Plata County has an aggressive program when it comes to weed management. We have developed our own methods for tracking and controlling weeds and have worked with many landowners to help manage weeds on private properties. Below are some of the methods that have helped to control weeds thus far in La Plata County.

What we do:
