Why are invasive species a concern in forestry?

Invasive species are a significant concern in forestry primarily because they can outcompete native species, disrupt ecosystems, and reduce biodiversity. These invasive species often have traits that allow them to thrive in new environments—such as rapid growth, high reproduction rates, and the ability to adapt to varying conditions—which enables them to establish dominance over native flora.

When invasive species proliferate, they can monopolize resources such as sunlight, water, and nutrients, making it increasingly difficult for native species to survive. This competition can lead to the decline or even extinction of native plants, which in turn affects the entire ecosystem that relies on those plants for food and habitat, thereby reducing overall biodiversity. The loss of native species can result in less resilience within the ecosystem, making it more vulnerable to diseases, pests, and environmental changes.

The other choices do not accurately capture the primary issues related to invasive species. For instance, while some invasive species may provide temporary habitat for certain wildlife, this does not mitigate the larger negative impacts on ecosystem dynamics and overall biodiversity. Similarly, it is not typical for invasive species to improve soil nutrient levels; in fact, they often disrupt soil health by altering the nutrient composition. Lastly, the assertion that invasive species can be easily managed through regular maintenance
