What is the main reason for establishing buffer zones around treated areas?

Establishing buffer zones around treated areas primarily serves to reduce herbicide drift to non-target areas. This is crucial in managing the environmental impact of herbicides and protecting surrounding vegetation, wildlife, and water sources from unintended exposure to chemicals. Buffer zones can act as barriers that help to absorb, filter, or dissipate any drifting herbicides, ensuring that they remain contained within the designated treatment area.

While enhancing visual aesthetics, increasing plant growth, and limiting moisture evaporation have their own merits in land management, they are not the primary objectives of buffer zones in this context. The focus is firmly on minimizing the risks associated with chemical applications, thereby safeguarding the ecosystem and promoting responsible vegetation management practices.
