Tree species selection in afforestation is crucial for enhancing biodiversity, soil stability, and resilience to pests. Choosing appropriate tree species contributes positively to the overall health of the ecosystem. Diverse tree species can coexist, providing habitats for various wildlife, which helps maintain ecological balance. Increased biodiversity can lead to more robust soil microbial communities, enhancing nutrient cycling and soil structure.

Additionally, selecting a mix of species can improve resilience against pests and diseases; some species may be naturally resistant to certain pests, thereby reducing the risk of widespread damage and promoting a healthier forest ecosystem overall. This strategic selection not only supports wildlife and soil health but also improves the ability of the forest to adapt to changing environmental conditions.

The other options do not capture the holistic benefits of tree species selection. Maximizing immediate profit from timber sales focuses on economic gain rather than ecological health. Decreasing biodiversity runs counter to the principles of sustainable afforestation, and solely prioritizing fast-growing species may neglect important ecological functions and long-term forest resilience.
