What are invasive species?

Invasive species are defined as species that, when introduced to a new environment, can rapidly spread and have a negative impact on native species and ecosystems. This can occur because invasive species often lack natural predators in their new environment, allowing them to proliferate unchecked. They can outcompete, prey on, or introduce diseases to native species, leading to declines or extinctions of those native populations. This disruption to the local ecosystem can also lead to changes in habitat and biodiversity loss, making the issue of invasive species a significant concern in ecology and conservation efforts.
