Which term describes species that are non-native and cause economic or environmental harm?

The term that accurately describes species that are non-native and cause economic or environmental harm is "aquatic invasive species (AIS)." AIS are organisms that, when introduced to a new ecosystem, can disrupt the natural balance by outcompeting native species for resources, spreading diseases, and altering habitats. This situation can lead to significant ecological impacts and economic costs, as these invaders can damage fisheries, recreational activities, and water infrastructure.

Understanding aquatic invasive species is crucial for effective pest management, as it highlights the importance of prevention, early detection, and rapid response to minimize their impact on native ecosystems and human activities. This terminology is widely used in environmental management and conservation contexts, further illustrating its relevance and significance in addressing issues related to non-native species.
