What could be a long-term impact of continuous oak tree removal in a forest?

1. Increased forest density

2. Forest regeneration

3. Loss of species diversity

4. Improved water quality

The correct answer is: Loss of species diversity

The long-term impact of continuous oak tree removal in a forest primarily leads to a loss of species diversity. Oak trees play a crucial role in their ecosystems; they provide habitat and food for a variety of wildlife, including birds, insects, and mammals. When oak trees are removed, many of the species that depend on them for survival may decline in number or be driven to extinction. This disruption can lead to an imbalance in the ecosystem, as other plants and animals that rely on the ecological niches created by oak trees and their associated species could also be negatively impacted. In addition, the removal of oak trees can lead to the dominance of a few species that are more resilient to change, thereby reducing the variety of species present in the forest. This effect not only impacts biodiversity but also affects the overall health and resilience of the forest ecosystem, potentially making it more susceptible to disease, pests, and changes in climate. Therefore, continuous removal of oak trees can significantly diminish the ecological richness of the area, resulting in a long-term degradation of species diversity.
