Dr. Mader will discuss the changes in the Florida Keys’ fauna and flora over recent decades, highlighting the impact of invasive species. Notable invaders include the Green iguana, pythons, Lionfish, Cuban tree frogs, Haitian curly-tailed lizards, Myna Birds, and Monk parrots. Invasive plants like Australian Pine and Brazilian Pepper trees also pose significant threats. Each new species, regardless of size, harms the sensitive ecosystem of the Keys.
