What is a key indicator of forest health?

• A. Biodiversity, including the variety of plant and animal species
• B. Presence of invasive species
• C. Number of trees planted
• D. Soil pH levels

Answer: (A)

Biodiversity serves as a key indicator of forest health because it reflects the complex interactions among various plant and animal species within an ecosystem. A diverse range of species indicates that a forest can maintain its resilience and stability in the face of environmental changes, diseases, and other stressors. Healthy ecosystems typically have a variety of plants, animals, and microorganisms, which contribute to nutrient cycling, pollination, and habitat structure, all essential for the forest's overall functionality. In contrast, the presence of invasive species can often disrupt local ecosystems, outcompeting native species for resources and destabilizing ecological balance. Similarly, the number of trees planted does not necessarily indicate a healthy forest, as simply increasing tree population without ecological considerations may lead to monocultures that lack the diversity needed for ecological stability. Lastly, while soil pH levels are important for plant growth and can affect overall forest health, they do not provide a comprehensive picture of biodiversity or ecosystem interactions, which are crucial for assessing the health of a forest. Thus, biodiversity stands out as the most comprehensive indicator of forest health.
