How do invasive species impact native ecosystems?

Invasive species have a significant impact on native ecosystems primarily through their ability to outcompete native species for resources. This competitive advantage can arise from several factors, including faster growth rates, higher reproductive rates, and a lack of natural predators that typically control their populations in their native environments. As invasive species proliferate, they may consume food, water, or space that native species rely on, leading to a decline in native populations.

For instance, an invasive plant might overshadow native plants, blocking sunlight and limiting their growth, while an invasive predator might reduce the numbers of native prey species. This competitive dynamic disrupts the balance of the ecosystem, ultimately leading to reduced biodiversity and alterations in community structure.

Consequently, understanding the impact of invasive species is crucial for conservation efforts aimed at protecting native biodiversity and maintaining healthy ecosystems.
