I have no idea how many tree frogs, Geckos, Anole lizards and toads we have around here. I'm sure they number in the 100's. Last year I had a kiddie pool that we set up for the toads to spawn in and we grew out close to 500 toads. Most of them I'm sure were eaten by something but I frequently see them hoping around. The tree frogs are the least seen. Not sure why. Maybe I'll figure out what they need to grow more numerous.
