Invasive Species Story: Cane Toads in Australia! By Mr.
Mitchell Bergstresser• Background: Cane toads were introduced to
Australia to combat the Cane Beetle!• This beetle was destroying the Sugar Cane crop
in Australia in the early 1930’s, which made farmers very angry.
• But the Cane Toad didn’t eat the sugar-cane… it ate everything else, and it’s population skyrocketed!
• Today the Cane Toad population is in the 100’s of millions!
• My precious crops! I’m ruined! We need to bring in some Cane Toads from Venezuela to kill these pesky beetles!
• I’ll eat all the crickets, fish, and food
that I find!
• That means no food left for you other frogs!
• And if you’re smaller than me, I’ll eat you too!
Extinct!! Extinct! Extinct!
Yum Yum!!
• Since I’m r-selected, and my babies are poisonous too, I’m going to reproduce like crazy and take this country over!
• Thank you, stupid farmers, for bringing me to this lovely land.
