What is the impact of invasive species on local ecosystems?

Invasive species significantly impact local ecosystems primarily by leading to ecosystem disruption. When non-native species are introduced to an environment, they can outcompete native species for resources such as food, water, and habitat. This competition can result in the decline or even extinction of native species, which disrupts the balance of the ecosystem.

Invasive species may also alter habitat structures, change nutrient cycling, and introduce new diseases, further affecting the native flora and fauna. For example, plants that are invasive can change the soil chemistry or light availability, impacting the growth of native plant species. This disruption can cascade through the food web, affecting not only plants but also the animals that rely on them for food and shelter.

Consequently, the introduction of invasive species can lead to reduced biodiversity, changes in ecosystem processes, and a loss of ecosystem services, which are crucial for environmental health and human well-being. Understanding these impacts is vital in efforts to protect and conserve local ecosystems.
