Island wildlife is often more threatened by invasive species due to their isolation and unique evolutionary adaptations, which make them more vulnerable to competition and predation. Many island species have evolved without natural predators or competitors, so the introduction of invasive species can disrupt their ecosystems and lead to declines in native populations. Additionally, limited habitat and resources on islands can exacerbate the impact of invasives, making it difficult for native species to adapt or recover. This combination of factors heightens the risk of extinction for island wildlife.
