What is the term for an invasive species that threatens natural resources?

The term "prohibited species" specifically refers to invasive species that are recognized as a threat to natural resources, ecosystems, or agriculture. These species are often regulated by law due to their potential to cause significant harm to native habitats and species. The classification as a prohibited species signifies that their introduction, spread, or cultivation is typically restricted to manage and mitigate their impacts.

Invasive species can outcompete native flora and fauna, disrupt food webs, and lead to habitat degradation. By identifying certain species as prohibited, regulatory agencies aim to prevent their introduction and minimize their spread. This proactive approach helps preserve biodiversity and protect natural resources from the adverse effects of these invasive organisms.

Other terms, like noxious weed, refer specifically to invasive plant species that cause economic or environmental harm, but they do not encompass the broad range of invasive species, including animals or microorganisms. Beneficial species refer to organisms that provide advantages within an ecosystem, while indicator species are those that reflect the health of an environment rather than posing a threat to natural resources.
