Which method is NOT a mechanical control strategy in vegetation management?

In the context of vegetation management, a mechanical control strategy encompasses physical methods used to remove or suppress unwanted plants without the use of chemicals. The chosen option, applying herbicides, is distinct from mechanical approaches as it involves the chemical application to kill or inhibit plant growth.

On the other hand, methods such as cutting unwanted plants, pulling plants by hand, and using machinery to till the soil all fall under mechanical control strategies. These approaches rely on physical action to disrupt the plants' growth processes. Cutting and pulling physically remove the plants from their growth substrate, while tilling the soil disrupts the entire area, potentially inhibiting the growth of undesirable species.

Understanding these distinctions is important in vegetation management practices, as they inform decisions on the most appropriate control methods based on environmental impact, effectiveness, and the management goals of the specific site.
