Weeds
Weeds are unwanted plants that can grow in a variety of environments. They can compete with crops and pastures for water, nutrients, and sunlight, and they can also harbor pests and diseases. Longhorn cattle may consume weeds as part of their diet, but they are not typically considered to be a major threat to weed populations.
Kudzu
Kudzu is a fast-growing, invasive vine that can quickly cover large areas of land. It is native to Asia, but it has been introduced to many other parts of the world, where it has become a major problem. Kudzu can smother crops and pastures, and it can also climb trees and buildings. Longhorn cattle may consume kudzu, but they are not typically considered to be a major threat to kudzu populations.
In conclusion, longhorn cattle may consume weeds and kudzu as part of their diet, but they are not typically considered to be a major threat to these plants.
