How can invasive species impact local ecosystems?

Invasive species can significantly disrupt local ecosystems by outcompeting native species for limited resources such as food, water, and habitat. When an invasive species is introduced to a new environment, it often lacks natural predators or controls that would normally keep its population in check. As a result, it can proliferate rapidly, leading to competition with native species that have evolved over long periods to coexist within their specific ecological niches.

This competitive advantage can lead to a decline or even extinction of native species, which are often less adaptable or resilient to the pressures imposed by invasive species. The loss of native species not only reduces biodiversity but can also alter ecosystem functions, such as nutrient cycling, pollination, and habitat structure. Ultimately, the encroachment of invasive species can destabilize entire ecosystems and reduce their ability to provide essential services to both wildlife and human populations.
