In forestry practices, what is an advantage of planting mixed-species forests?

Planting mixed-species forests can significantly promote greater biodiversity, which is a major advantage of this forestry practice. Biodiversity refers to the variety of plant and animal life in a particular habitat. Mixed-species forests support a wider array of organisms compared to monoculture stands, where only one species is planted. This increased biodiversity can lead to a more resilient ecosystem, where different species interact in ways that enhance the overall health of the forest.

For example, diverse root systems from various tree species may improve soil structure and nutrient cycling, while a variety of canopy layers can provide different habitats for wildlife. Additionally, a mix of trees may offer varied food sources for animals, thereby attracting a wider range of fauna. This complexity can help maintain ecosystem functions and resilience against pests and diseases.

This approach contrasts with monocultures, which often lead to vulnerability because if a single pest or disease targets the dominant species, the entire planting can be at risk. Thus, promoting biodiversity through mixed-species forests contributes not only to ecological balance but also to ensuring long-term sustainability in forestry practices.
