Animal Invaders: Destroying Native Habitats

Though stink bugs weren't introduced to the United States until the 1990s, this invasive species has spread to nearly every state in the country. Their biggest enemies? Farmers who don't like them feeding on crops and fruits. Readers don't need to smell a squished stink bug to understand the harm they can cause not only to crops, but also to native species. The main content and fact boxes discuss how the stink bugs ended up in the United States and the efforts being made to stop their population from growing even more.

Bullfrogs in the United States started as a way for Californians to eat more frog legs. Now, the bullfrog population grows almost completely unchecked. In many places in the world where bullfrogs have spread, there aren't predators to eat them! Readers are likely familiar with the bullfrog croak, but in this book, they'll learn why hearing it is a bad sign! The main content introduces the definition of "invasive species" and explains through the bullfrog's story the harm these animals cause. Full-color photographs help readers identity bullfrogs, and informative fact boxes add details about conservation, habitats, and food chains.
