Natural enemies are friends of the forest

What if a disease caused by a fungus could be a good thing? It might seem unlikely, but it is, in fact, possible, if the target of the disease is a highly invasive forest tree species. An essential component of integrated pest management (IPM), biological control involves the use of natural enemies against pests and invasive species. In a broad sense, natural enemies are organisms that cause the death or impairment of other organisms, such as pests or invasive species. FAO promotes biological control for forest ecosystem preservation.
