The role of forest pests and diseases is multifaceted, and option C effectively captures this complexity. While pests and diseases can indeed have detrimental effects on the health of trees and the overall forest ecosystem, they also play a vital role in maintaining ecological balance.

Pests and diseases can contribute to the natural selection process within forest ecosystems. For example, they can target weaker or less resilient trees, allowing more robust specimens to thrive and ensuring genetic diversity. This natural regulation helps maintain the health of the forest over time, preventing overcrowding and promoting a balanced ecosystem.

Moreover, some pests act as food sources for various wildlife species, thus integrating into the food web. Their presence can stimulate the growth of new vegetation by opening up the canopy and allowing light to reach the forest floor, which can benefit understory plants and a diverse range of organisms.

While it is true that certain pests and diseases can lead to significant economic losses and affect timber quality, their role extends beyond mere harm. Ignoring their ecological contributions would overlook important dynamics in forest management and conservation strategies.
