- IUCN, the World Conservation Union, states that the impacts of alien invasive species are immense, insidious, and usually irreversible. They may be as damaging to native species and ecosystems on a global scale as the loss and degradation of habitats. Hundreds of extinctions have been caused by invasive alien species.

For example, the mongoose threatens endemic species on tropical cane-growing islands. They have caused the population demise or extinction of many endemic vertebrates, and continue to cause livestock damage while posing a disease risk. European red foxes introduced into Australia and temperate regions of North America have negative impacts on many ...
Species that appear in new environments may fail to survive but often they thrive, and become invasive. In fact, native species are likely to be unprepared to defend themselves against the invaders. This process, together with habitat destruction, has been a major cause of extinction of native species throughout the world in the past few hundred ye...
Biologists are investigating how these "invaders" succeed in establishing themselves in new environments, so that they can be controlled and eradicated where necessary.
May 24, 2023 · Invasive alien species are one of the biggest drivers of biodiversity loss and species extinctions. Biological invasions also put human health, food security and livelihoods at risk, as highlighted in the United Nations Sustainable Development Goal 15.
Invasive alien species threaten livelihoods, water and food security, economies, and human health.
Sep 6, 2023 · More than 3,500 invasive alien species are seriously compromising human well-being and causing irreversible damage to ecosystems, according to the Intergovernmental Science-Policy...
Indirectly, invasive species may cause native species declines due to resource competition and habitat alteration (Davis 2009). For instance, plant invasions have been demonstrated to alter carbon and nitrogen cycles and fire regimes in invaded ecosystems (Simerloff and Rejmánek 2011).
The impacts from invasive alien species (IAS) can be compounded by climate change – the change in the Earth’s climate due to rising greenhouse gas emissions. Extreme climatic events resulting from climate change, such as hurricanes, floods and droughts can transport IAS to new areas and decrease the resistance of habitats to invasions.
