The Unnatural History of Invasive Species in the Florida Keys: Paradise Threatened but not Lost

Non-native species are animals and plants living outside of their native ranges as a result of human activity. The specific introduction of a species to an area can occur intentionally or unintentionally. A few introduced non-native species will become established (breed) and can become invasive species capable of harming ecosystems, economies, or human health and safety. The establishment of invasive species can follow a trend known as the “invasion curve.” The longer invasive species remain in an area, the more severe their impact, the higher the chance for their distribution, and the greater the expense to manage them. Invasive species like the Burmese python and the lionfish have already harmed Florida Keys ecosystems. The Keys are particularly susceptible to invasion because of their tropical climate, island geography, and abundance of the disturbed habitats that help invasive species establish and spread. Early detection of new species is vital to saving Keys native species.

The Stages of Invasion: How does a nonnative species transition to an invader?

Deah Lieurance, Amy Kendig, and Christina Romagosa

This publication describes why invasive species are an important issue in Florida and how nonnative species become invasive by moving through five stages of human-aided biological invasion. Written by Deah Lieurance, Amy Kendig, and Christina Romagosa, and published by the UF/IFAS Agronomy Department, July 2022.

Growth and Spread of the Argentine Black and White Tegu Population in Florida

Rebecca G. Harvey, Justin R. Dalaba, Jenny Ketterlin, Art Roybal, Daniel Quinn, and Frank J. Mazzotti

The Argentine black and white tegu is one of the largest lizard species in the Western Hemisphere, growing up to four feet long. The tegu’s broad habitat use and omnivorous diet create the potential for severe ecological impacts in areas outside its native habitat. This publication presents updated information about efforts to understand and manage the problem of invasive tegus in the state of Florida. It presents the implications of continued expansion of their range.
