What are the potential consequences of invasive species on local ecosystems?

The consequences of invasive species on local ecosystems often include significant disruption of the food chain and native species populations. Invasive species are non-native organisms that, when introduced to a new environment, can outcompete, prey on, or bring diseases to native species. This competitive edge can lead to the decline or extinction of native species, resulting in a loss of biodiversity. The introduction of these invaders often alters habitat structures, nutrient cycles, and the overall ecological balance.

In addition, as native populations are displaced or diminished, the food web can become imbalanced. Predators may lose their natural prey, while herbivores may overconsume remaining native plants, leading to further ecological degeneration. The cascading effects can alter ecosystem services that humans rely on, such as pollination, water purification, and soil stabilization, highlighting the extensive impact invasive species can have on both local ecosystems and broader environmental health.
