Which factor is enhanced by tree species diversity in a forest ecosystem?

Tree species diversity plays a significant role in enhancing ecosystem stability and resilience. A diverse range of tree species can support a broader array of wildlife and biological interactions, creating a more balanced and stable ecosystem. When a forest has a variety of tree species, it can better withstand various stresses such as pests, diseases, and climate change. This diversity acts as a buffer, allowing the ecosystem to recover more quickly from disturbances.

For instance, if one species is affected by a disease, other species may not be susceptible, thus maintaining the overall health of the forest. Diverse ecosystems are generally more resilient, as they can adapt to changes and fluctuations, thereby ensuring their long-term sustainability. This concept is fundamental in forest management and conservation strategies, emphasizing the importance of maintaining biodiversity within forested areas.

Other factors, such as timber market value, soil nutrient availability, and air quality improvement, are related but do not directly address the primary benefit that comes from having a wide variety of tree species in terms of supporting ecological processes and promoting stability in the forest ecosystem.
