Weeds

Weeds are basically plants that are interfering with how we think our property should look. How a landowner manages their property can influence the number and type of weeds that they have. Over-grazing pastures is one of the main reasons that weeds get a start on a property. There are multiple methods landowners can use to manage their weeds, but the first step is to positively identify the weed.

In simple terms a weed is just a plant out of place, however, managing some of these weeds is not a simple task. Noxious weeds are invasive non-native plants whose control is mandated by law. These plants pose a serious threat to native habitats, impact recreation and agriculture. They have displaced 130 native Colorado plants on 553,163 acres* in Colorado (*Colorado Dept of Agriculture).
