Which management strategy is NOT suitable for planted forest stands?

The choice of planting fast-growing, nonnative seedlings is not suitable for planted forest stands primarily because it can disrupt the local ecosystem and biodiversity. Nonnative species often lack natural predators and may outcompete native flora, leading to a decline in native plant populations and the wildlife that depends on them. Additionally, introducing nonnative species can result in unforeseen ecological consequences, such as altered soil composition and changes to local water cycles, which may harm the ecosystem in the long run.

In contrast, planting disease-free seedlings, establishing mixed-species stands, and matching tree species to site conditions are all strategies designed to promote healthy, diverse, and resilient forest ecosystems. These approaches help in reducing susceptibility to pests and diseases, enhance biodiversity, and ensure that the planted species are well-adapted to local environmental conditions, ultimately contributing to the long-term sustainability of the forest stand.
