Exploring the role and impact of non-native species in our ecosystems
Non-native species (also known as alien, exotic, or introduced species) are organisms that have been moved—intentionally or accidentally—outside their natural historical range by human activity.
While some non-native species integrate harmlessly into new environments, others become invasive, outcompeting native species and disrupting local ecosystems.
Originally from Eastern Europe, these mussels clog water infrastructure and displace native mollusks.
Introduced to control pests, they became a major predator with toxic defenses harming native wildlife.
Known as “the vine that ate the South,” it smothers trees and structures under rapid growth.
Managing non-native species requires prevention, early detection, rapid response, and long-term control strategies.
