When I was a kid, there was a vernal pond where we would go to gather tadpoles. They paved it over to make a bank parking lot. There was also a creek across the street that they put in concrete tubes and buried. No more frogs, crayfish or turtles around there anymore.RaZ- why are you wanting amphibians for your property?
A few years ago when I installed my pond, American toads found it and bred there. I love hearing the mating calls of frogs and toads. Even though I'm in the burbs I'm trying to make my little slice just a bit more natural.
On a side note, I've been hearing a red wing blackbird in the morning. They like to nest near water.
