Interesting reading. Great ideas. I will be doing my ponds for frogs mostly. The development is going to get bad here at some stage and I want to get frogs breeding and homing back to ponds here before it is too late. The problem is a few frogs breed in ephemeral inundating shallow water and soaks. I just don't know how to create these.
As well, with ponds at ground level the introduced Cane Toad just takes over with females laying 30 thousand eggs in one sitting. Becky, you should see this tadpole problem of thousands of black, very poisonous toadpoles. I can get round toads because they can't climb but in doing so one eliminates the non-climbing native frogs, of which there are many. Ponds were not meant to be easy I suppose.
