Cane Toads: Small Toads, Big Problem – Ecosystem Impacts Explained

This PowerPoint presentation by Nick Wasmund explores the significant impact of introduced species, focusing on Cane Toads (Bufo marinus). Aimed at high school biology students, it covers the toad's origins in Central and South America, their lethal venom, and their introduction to Australia in 1935 to combat pest beetles. The presentation outlines the environmental consequences of Cane Toads, including the decline of native wildlife such as goannas and crocodiles. Additionally, it discusses the ongoing challenge of managing their population and protecting biodiversity.
