Everglades National Park is surrounded by Miami-Dade (~ 2.50 million residents),
Broward (~ 1.75 million residents), and Collier (~ 0.32 million residents) Counties. The
demands of these 4.5 million residents exert a significant impact on the resources of
Everglades National Park, presumably mostly on air quality and water quantity and
quality. |
Invasive alien species |
very important |

Non-native (exotic) plants are a significant threat to the native plant communities of Everglades National Park. Approximately 1,000 plant species have been recorded in the park. Of these, over 220 species are non-native.
Exotic invasive pythons have altered the food web of the
Everglades: this species is a top predator, and feeds on a broad variety of native species.
Exotic fish species are widespread in freshwater marshes, although we have not
determined that the species are negatively affecting native fish populations. Because
control methods for exotic freshwater fish in the marsh are scarce or non-existent, these
species may remain in the Everglades freshwater fish community for a very long time.
The presence of lionfish (Pterois volitans) in Florida Bay is cause for concern: this
species is also a top predator, and has been shown in other locations to have negative effects on populations of native fishes. |
