What defines invasive species?

Invasive species are specifically defined as non-native organisms that, when introduced to a new environment, can disrupt or harm local ecosystems. These species often thrive because they lack natural predators or competitors in their new habitat, allowing them to proliferate and outcompete native species for resources like food, water, and space. The presence of invasive species can lead to significant ecological changes, potentially resulting in the decline or extinction of native species and disrupting the balance of the local ecosystem.

The concept of invasive species emphasizes the ecological impact that comes from the introduction of species that are not originally part of an ecosystem. This disruption can affect biodiversity and ecosystem functions, leading to long-term negative consequences for the environment. Understanding this definition highlights the importance of managing and controlling the spread of invasive species to protect local biodiversity and ecosystem health.
