How have invasive pythons impacted Florida ecosystems?

Non-native Burmese pythons have established a breeding population in South Florida and are one of the most concerning invasive species in the area. Pythons compete with native wildlife for food, which includes mammals, birds, and other reptiles. Severe declines in mammal populations throughout Everglades National Park have been linked to Burmese pythons, with the most severe declines in native species having occurred in the remote southernmost regions of the Park where pythons have been established the longest. A 2012 study found that populations of raccoons had declined 99.3 percent, opossums 98.9 percent, and bobcats 87.5 percent since 1997 (Mammal Decline). Marsh rabbits, cottontail rabbits, and foxes effectively disappeared over that time (Marsh Rabbits Mortality).
