Which of the following is NOT a method of vegetation management?

The correct answer indicates that fertilization or landscaping is not considered a method of vegetation management in the context of controlling pest populations or invasive plants. Vegetation management generally focuses on strategies specifically aimed at controlling unwanted plant species or pests that hinder or threaten the desired vegetation, often found alongside roadways or other rights-of-way.

Mechanical control, chemical control, and biological control all play significant roles in pest management by targeting specific plant species or pest insects. Mechanical control involves physical removal or alteration of plants, chemical control uses herbicides or pesticides to manage growth, and biological control involves using natural predators or diseases to regulate plant populations.

On the other hand, fertilization or landscaping primarily aims to enhance the growth and health of desired plants rather than control or eliminate unwanted vegetation. These practices can support plant longevity and aesthetics but do not directly address management of plant populations or pest issues in the way that the other methods do.
