| Two different species of frog are known to live on the Quilpie Nature Reserve: speckled greenbacks, and red sentinels. Ahmed and Melissa are investigating the populations of the two species, and have done an experiment. |


Ahmed: “For a whole year, every time a frog was spotted on the reserve, we made a note of which species it was. Over the year, we recorded 113 red sentinels and only 15 speckled greenbacks."
Melissa: “That tells us that red sentinels are much more common on this reserve, and speckled greenbacks are actually quite rare.”
