[ARCHIVED] Spring 2017 Invasive Weed Management Continues

Springtime invasive weed management operations within right of way boundaries along County roads are continuing.

This week’s springtime invasive weed management operations were conducted along Lake Mary Road. The Doney Park and Fernwood areas are slated for treatment next week, weather permitting. These operations have been completed along County roads in the Baderville, Fort Valley, Kachina Village, Lake Mary, Mountainaire, Munds Park, Parks, Pine Dell, Williams and Schultz Flood areas.

Springtime invasive weed management operations are being conducted within right of way boundaries along County roads. The County’s contractor, under the supervision of Natural Channel Design (NCD), is using a broadleaf herbicide for these spot treatment operations. The herbicide, which does not target native grasses and dries quickly, is being applied with a blue indicator dye so that treated areas can be clearly identified. 

These operations are targeting invasive weeds that include diffuse knapweed, musk knapweed, Scotch thistle, Russian thistle and Horehound. These are highly invasive plant species that can quickly dominate areas of disturbance and outcompete desired native vegetation. Spring weed management operations are expected to be completed within the next two weeks, weather permitting.  

Removal of invasive weeds supports native plant revegetation. The timing of treatments is critical to prevent seed set. Spring is the optimal season for herbicide treatment as invasive weeds are small and actively growing. The County also is planning to conduct mechanical weed removal operations on County roads late this summer. For more information on invasive weed removal please visit
