What can lead to healthier forests capable of resisting pests?

The choice of planting diverse species is particularly beneficial in fostering healthier forests that can better resist pests. Biodiversity within a forest ecosystem plays a crucial role in increasing resilience against diseases and pests. Different species may have unique natural defenses, and when various types of trees and plants coexist, they can form a more balanced ecosystem. This diversity can reduce the likelihood of pests establishing large populations, as they are less likely to target or thrive in a mixed-species forest.

Additionally, diverse species can enhance soil health, improve nutrient cycling, and increase habitat complexity, which is vital for many other organisms that can help control pest populations naturally. These factors collectively contribute to creating an ecosystem that is robust and less susceptible to pest infestations, allowing for a healthier forest overall.

While higher density of trees and regular management practices can play roles in forest health, they do not specifically address the critical aspect of biodiversity in relation to pest resistance as effectively as planting diverse species does. Hence, while those aspects are important, the choice that most directly contributes to resisting pests within forests is indeed the cultivation of diverse species.
