Frog species in some areas of the world appear to be in rapid decline. We believe that tracking frogs tells us a lot about the health of our environment. If things don’t go well for them, that could be an indication of bad things for people because frogs absorb oxygen through their skins and spend most of their time in the water.

Frog populations are down in parts of Australia, California and Costa Rica. No one is sure why, but to get a better handle on the situation, we need better estimates on populations.
