I have two ponds in my back garden and they certainly encourage loads of extra wildlife to the area! I've had seen beautiful dragonfiles, frogs, toads and newts in mine to name but a few, and the attracted bird life is staggering! I've written a short guide to building your own wildlife pond, have a look at - http://animalsunlimited.co.uk/conservation/how-to-build-a-wildlife-pond/ - although I can't pretend my writing is as polished as the articles on this website I can say I try my best!
