I built two ponds in my garden, one is a natural clay pond with gentle slopping sides to about 1m and is surrounded by a bog garden and is itself full of native plants to provide shelter. The other is a concrete lined pond with vertical sides down to 1m with the middle down to 2.3m. Around this pond is a shallow area which is about 30cm deep which is full to within 2-3cm of gravel with mostly non native plants and some tropical pond plants in summer in it. There are virtually no plants in the middle straight sided section so that we can swim in it. I have however noticed that I get all my toads, frogs, common and great crested newts in this second concrete straight sided pond and virtually none in the natural clay one. I think the reason for this is because this pond has straight sides and with no shelves, a heron and other predators cannot stand in the vertical sided pond and reach down 1m so my amphibians all feel safer and they can get out in the shallow bit when they need to. Has anyone else found this is the case? We may all need to re-think what a wildlife pond really should be like.
