Invasive species pose a serious threat to South Florida’s native ecosystems. In the Everglades, invasive fish prey on native species, while invasive plants like melaleuca outcompete and overshadow native vegetation. Far from their original habitats, these invaders often thrive in disturbed areas, where they have a competitive edge. Without natural predators to keep them in check, invasive species spread rapidly—consuming sunlight, water, and nutrients that native plants and animals need to survive. The result is intense competition that weakens the health and diversity of the Everglades ecosystem.

 

In addition to causing environmental damage, invasive species also have significant economic impacts—especially in Florida, where the warm climate and diverse landscape make it easier for them to take hold. While some of these invasive species may be here to stay, we can slow their spread by preventing the release of non-native plants and animals into the wild and actively managing those already invading natural areas.

To address the issue of invasive plant and animal species, the South Florida Natural Resources Center of Everglades National Park created the following resource management programs and uses them for guidance:
