The main impact of invasive predators on native species is the disruption of local ecosystems, leading to declines or extinction of vulnerable species. Invasive predators often prey on native species that lack defenses, resulting in population decreases and altered food web dynamics. This disruption can decrease biodiversity and change ecological interactions. Managing invasive species is crucial for protecting native fauna and restoring ecosystem balance, as they can outcompete or eliminate native species, leading to significant ecological consequences.
