Which of the following is NOT a silvicultural practice?

Cultivation is generally associated with agricultural practices aimed at preparing and managing land for crop production, rather than silvicultural practices which specifically pertain to the management of forested areas. Silviculture involves techniques that enhance the growth and health of forest stands, including practices that promote regeneration, thinning, and controlling undergrowth.

In contrast, prescribed burns, herbicides/pesticides, and reforestation are all integral to silvicultural practices. Prescribed burns are used to manage underbrush and reduce the likelihood of uncontrolled wildfires, while herbicides and pesticides help control pests and invasive plant species that threaten forest health. Reforestation is the practice of replanting trees in areas where they have been cut down or have naturally deforested, directly aimed at restoring forest ecosystems. Therefore, cultivation stands apart as it does not pertain specifically to the practices associated with managing forest environments.
