How does the Asian long-horned beetle reduce the biodiversity in a local environment?

The Asian long-horned beetle reduces biodiversity by infesting and killing a variety of hardwood trees, such as maples and oaks, which are vital components of their ecosystems. As these trees die, the habitat and food sources for numerous species, including birds, insects, and mammals, diminish, leading to a decline in local populations. Additionally, the loss of these key tree species can disrupt ecological processes and alter the overall structure of the forest community, further contributing to reduced biodiversity.
