Invasive plants are disruptive pests that agricultural producers have been dealing with for years. They reduce crop production and can limit forage available for livestock. In order to maintain a certain level of production, invasive plants must be controlled. There are considerable costs associated with controlling invasive plants, especially over large areas, with traditional methods like mechanical or chemical control. Many invasive plants are considered unpalatable for livestock, but studies have shown that livestock are creatures of habit; they will eat what they are taught to eat by their mothers. 

Producers can train their livestock to seek out and eat desired plant species. By using livestock to control invasive plants, the cost of traditional control with be greatly reduced. As well, the time spent controlling invasive plants can be diminished and replaced by other tasks. Studies have compared the nutritional values of invasive plants to more traditionally grazed plants; many invasive plants can be just as or more valuable as forage. The CCCIPC has collected and analyzed the nutritional values of local invasive plants. 

Nutritional Values of Invasive Plant Moisture Dry Matter Crude Protein TDN*
Dalmation Toadflax 72% 24% 8% 63%
Oxeye Daisy 78% 22% 8% 61%
Spotted Knapweed 63% 37% 10% 65%
Sulphur Cinquefoil 67% 33% 6% 61%
