Invasive species are a threat to frog populations world wide but what is an invasive species? An invasive species is a non-native species that has a negative impact of the environment. They can be both plants and animals. These introduced species thrive in their new areas since they lack their natural predators and don’t have to compete against organisms that limited their growth in their native environment.
These organisms can be purposely released in the new environment or by accident. Often, these organisms are released into an area to stop a problem, but actually cause even more problems. The Cane Toad was introduced to Australia to reduce insects harming sugar cane crops but the Cane Toad spread and caused harmed to other native species.
These species can out compete the native species for resources, introduce new diseases, and prey on the native species.
There are even invasive frog species that are bad for other frogs. The American Bullfrog is an invasive species around the world. With its large size and appetite, it devours anything that it can fit into its mouth – including other frogs.
