There are many threats to the integrity of South Florida’s delicate ecosystems, but none as pervasive and threatening as non-native, invasive plants and animals. After habitat destruction, invasive plants are the next biggest threat to biodiversity. Non-native species are not native to an ecosystem and which cause, or are likely to cause, economic and environmental harm or harm to human health. Our natural resources are threatened by the disruption in ecological processes caused by invasive species. Treatment and management of invasive species has been identified as one of the highest priorities within the National Wildlife Refuge System.
